Hello Capt. Paul

I have been looking into getting a gps. I was reading reviews on the Oregon 650t and the Montana but its seems like some people like and don't like the garmins. What would you recommend? garmin or different brand? Or is there something else I should look into? I will be using it for hunting and fishing. any info will be appreciated.

Thanks you

Garmin is top of the line equipment
~ Captain Paul's response to: ~Cajun Man ~

I have a hand held Garmin that I love. I believe that Garmin has a very user friendly operating system. Their units can deliver an accuracy within 9.8 feet. I have the Garmin GPSMAP 65st because my thick fingers have difficulty using some of the touch screen models.

The trick is to get the model designated with a 't'. The 't' means that it is preloaded with Topographical maps of the U.S. in 1:100.000 scale. In addition, it can be loaded with supplemental Topo maps in 1:24000 scales. This is the same scale at U.S.G.S. topo Quads, and is great for hunting and fishing the coastal marshes. Some units have a 's' model together with the 't' making it as a 's t' model. The 's' indicates sensors. A Compass, and barometer/altimeter and some even an 8 megapixel autofocus, digital zoom camera with flash/torch.

They can also accommodate their Birds Eye aerial mapping as a download by different areas. The 1:24000 and Birds Eye are sold on their web site and at many internet sites at a reduced price. They also have connecting cables which allow you to use the 12 volt power of a vehicle to extend the operating time of the unit.

If you couple one with preloaded topo maps and their free Data Transfer program called BASE CAMP, you can transfer waypoints, tracks, and routes between the GPS unit and a computer. This allows the user to type the waypoints in the computer program and transfer them in bulk into the GPS unit.

That is an unbeatable combination.

Go to a stocking Garmin dealer and get a “hands on” experience with the different models, you won’t be disappointed.

Hello everyone,

I just moved here from Japan and bought a 18' Kenner Bay Boat. I need some tips on what gps/FF to get for fishing inshore for specks and reds. I had a Lowrance Elite 7 on my Jet ski in Okinawa, and I am leaning toward the New chirp elite 7.

How much are the standard maps? I will be fishing near Slidell mostly.

~ Captain Paul's response to: ~ hrforsale ~

Some of the series of Lowrance GPS Chirp units do not have a GPS counter part to its side scan sonar.

I suggest that you speak to a stocking Lowrance dealer to insure that you purchase the unit that will best suit your needs.

Standard Mapping has several maps that should work in the unit, but be sure that you purchase the right type of memory card for your unit.

Check with Standard Mapping at http://www.standardmap.com/ to get their best mapping for your fishing area.

~ Captain Paul's response to: ~ Confused Snapper Fisherman ~

According to George Mason University @ http://mbac.gmu.edu/mbac_wp/gulf_wrecks/halo-1942/

“Halo is a steam tanker built in 1920 and owned by the Cities Service Oil Company. With a keel length of 436 feet and beam of nearly 56 feet, the 6,986-ton tanker carried a cargo of 63,000 barrels of crude oil on her final voyage from Galveston, Texas to New Orleans, Louisiana. In the early hours of May 20, 1942 approximately 50 miles from the Mississippi River’s Southwest Pass, U-506 attacked the unarmed Halo, firing two torpedoes into her starboard side. The first torpedo struck near the bridge while the second struck just aft of the bridge. As the tanker exploded and began to sink, the crew scrambled to escape the flames. Only one life raft was successfully launched. Out of 42 men on board Halo, only 23 escaped the vessel before she sank. In the hours after the attack, oil burned on the water and survivors clung to whatever debris floated to the surface. Five days later, the Mexican steamship, Oaxaca, rescued two survivors – one who later died at the hospital – and a third man who had recently perished. Two days after that, the British tanker, SS Orina, rescued two more men from a life raft. The other 18 men who entered the water died at sea.

Halo remained undiscovered for nearly 60 years until 2000, when a deep-tow hazard survey performed by C&C Technologies for Pogo Producing Company discovered the shipwreck in the Grand Isle leasing area near Pogo’s proposed pipeline route. Lying in more than 450 feet of water, the shipwreck was identified by C&C marine archaeologist Rob Church as the remains of Halo.

During the 2004 Deep Wrecks project, a study partly funded by BOEM (then MMS), Halo was one of several shipwrecks investigated by archaeologists using a Remotely Operated Vehicle (ROV). The purpose of the study was to examine the artificial reef effect of shipwrecks and learn more about shipwreck degradation and metal corrosion processes. ROV video footage and rusticle, biological, and sediment samples were collected. Several species of corals, invertebrates, crustaceans, and other fauna were observed on and near the wreck. Biological experiments and bio-battery coupons were placed on site to measure microbial concretion and biofilm formation and the electrical potentials (voltages) of in situ metals. The study found that Halo was “dominated by concretious growths over most of the hull and so the major iron losses…would be dependent upon the rates at which iron moves out through the concretions into the oceanic environment. Some rusticle activity was evident on Halo and this may mean increases in the rate of iron loss from the steel.” (Church et al 2007:206)

Researchers concluded, “From this investigation, the primary observations are that all the ships (investigated during the study) have become heavily infested with attached biological activity that varies from ship to ship. Depth may be a factor since the ships sit along a transect line from 87 meters to 1,964 meters. Depth cannot be the only influencing factor since the ships also sit within influence of the Mississippi River’s discharges. Clearly…Halo, being closer to these discharges already exhibit(s) the effects of the more eutrophic environment causing thicker attached growths and a greater density of fish populations.” (Church et al 2007:207).'

End Quote.

My information is that the site of the Halo wreck is located at or about

28.700239 ° N. Latitude ~ 90.133403°W. Longitude. I believe that it is in about 500 feet of water and at certain times there is an abundance of fish around the wreck.

Unless otherwise specified, all positions are stated as Decimal Degrees (DDD.dddddd) and were determined using WGS 84 Datum. All bearings and courses are stated in Magnetic degrees.

Captain Paul's Response

I suggest that you go to a stocking Navionics dealer and view the two mapping programs for your self. I believe that the LAKE MASTERS primarily covers some of the lakes on the Bass tournament circuit. It has some of the many Louisiana lakes, but not all.

The Navionics program is designed from a NOAA Marine chart. It would show established marine channels in the area that it depicts.

As I Said, you will have to actually view what the maps look like and see if either covers your prime area.

You should be able to use either mapping program, but there usually no returns on this kind of software.

I do not provide physical memory cards or “Chips” of maps. The CAPTAIN PAUL FISHING EDGE programs are electronic downloads of fishing waypoints. These files area downloaded into your computer, then using a manufacturer’s data transfer program, in your case HUMMINBIRD PC, to view and transfer the data on to a spare memory card which is then loaded into your GPS unit. I have files written in the required Humminbird protocol for their data files.

As for the actual mapping, Humminbird units can ONLY use those specific mapping programs that are designed for their units. For marine use they specify certain models of Navionics mapping.

Go to the Humminbird web site (www.humminbird.com) and search for mapping accessories for your unit. Before making up your mind, go to a stocking Humminbird dealer and actually view the maps in a GPS unit like the one you have. Zoom in on your fishing areas and see if the map meets your fishing and navigation needs.

Response by Captain Paul

Grey Duck lake
~ Captain Paul's response to: ~ RESPECKTER ~

The area you describe is, I believe a common name for Bay Courant.

According to a story published on the Louisiana Sportsman Magazine Web site titled “The time is right to catch speckled trout south of Golden Meadow,” by Anthony Taylor April 08, 2013 at 9:58 am, Taylor relays information for fishing the Golden Meadows area.

The story reads,

“A question that any angler asks himself when he’s got a variety of live and artificial baits at his disposal is, “What should I use?”

The answer lies in timing. Some basic guidelines should be realized, however, if you’re going to hit the water around Catfish Lake in search of speckled trout this spring.

Capt. Vernon Ledoux with Bayou Boyz Fishin has been fishing areas from Catfish Lake to Grand Isle for 12 years and has noticed a few important patterns.

According to Ledoux, the cocahoe minnow hatch begins in late March, and the little baitfish take center stage as a main food source for speckled trout through the later part of April. In late April and early May, shrimp begin to thrive once more in the coastal waters of South Louisiana, taking the cocahoe’s place as a speckled trout’s favorite meal.

“We call it matching the hatch,” Ledoux said as he dumped 50 live cocahoe minnows into his livewell, preparing to try for an afternoon bite. “You have to match the bait, whatever is in season. Right now it’s cocahoes; later on it will be shrimp.”

Ledoux launched his brand new Sea Hunt BX 24 BR and made his way to the northern bank of Catfish Lake. After arriving at the mouth of one of the multiple bayous along the lake’s northern bank, Ledoux’s stepdaughter rigged a live cocahoe under a cork, made a cast and almost immediately hooked up with a speck.

“There are good oyster reefs and bayous all over this bank, and the fish are in the lake, which is a good sign,” Ledoux said.

After catching a few more trout, the bite slowed, and Ledoux switched to a Matrix Shad Lemon Drop on a ¼-ounce Rockport Rattler jighead.

“By late April and May, it will be on fire in here, and I will be able to use plastics all of the time,” Ledoux said. “I will also use topwater lures from now through the summer during the two hours after sunrise and before sunset. I love fishing topwater; some people try to set the hook when they see the splash, but that’s usually just the trout whipping it with its tail. You want to feel that pull before you set the hook.”

When thinking about artificial lures, the clarity of the water, the live bait living where you’re fishing and the weather are all variables to take into consideration.

“If the water is clear and you have a clear day, you want to go with a clear or white lure,” Ledoux said. “You also want to use a lure that resembles the kind of bait in the water at the time.”

After a few more casts, the bite seemed to wane and Ledoux made a move to an area that locals call “Big Grey Duck”, otherwise known as Bay Courant.

While powering through a passage between Little Grey Duck and Big Grey Duck, he pointed out rows of PVC pipes on either side of his boat.

“You have to be careful in here; always stay between the poles,” Ledoux said. “It can get dangerous on either side because of some shallow oyster reefs.”

As Ledoux idled through Bay Courant, ripping tidelines bustled with mullet and minnows near the bank and his in-dash fish finder showed a drop from four to 18 feet deep.

“There’s a ledge near the bank here. Any change in depth, even if it is small, will usually have fish around it,” said Ledoux, who anchored down and watched his party catch fish from 14 to 21 inches on cocahoes rigged under cork.

“There really aren’t many school trout here right now so there isn’t much competition,” Ledoux said.

In late April into May, the bite will be on and fish will be stacked up all the way from Catfish Lake to Barataria Bay. “ End quote.

If that is the area you are asking about, Grey Duck and Little Grey Duck (Bay Courant and Little Bay Courant) are located about 2.5 miles south of Clam Lake via Bayou de Valle. They are east of Bayou Jean Lacroix and the Terrebonne~Lafourche parish boundary. It is also west of Bayou Courant, Bayou Tete d Ours and Grand Bayou Blue, about six miles at 242° Magnetic as the crow flies from Golden Meadow and directly north east of Deep Lake.

Bayou de Valle enters the smaller part of bay Courant at or about ~ N. Latitude 29°0.535’ ~ W. Longitude 90° 21.2170’. The bayou continues southward in the upper part of the lake to a point where the east and west shorelines begin to converge. This is basically the point where the larger part of the bay meets the smaller part. This is located at or about N. Latitude 29° 19.3751’ ~ W. Longitude ~ 90°20.8989’. Moving southward again the bay continues into Chinaman Bayou and Chinois Pass, which is at or about ~ N. Latitude 29°17.8864’ ~ W. Longitude 90° 20.2640’. There are a series of Aids to Navigation day markers beginning is Deep Lake marked as Green #1, G #2, G #3, G #4, G #5, etc., and continuing northward to Green #19 in that area.

Unless otherwise specified, all positions are stated as Degrees, minutes and thousandths of minutes (DDD,MM.mmm) and were determined using WGS 84 Datum. All bearings and courses are stated in Magnetic degrees.

The Humminbird 386ci-Combo is considered a LEGACY ( Discontinued) product. See http://www.humminbird.com/Products/386ci-Combo/

As such accessories will be getting scarce and in some cases impossible to obtain. I recommend that you get what you need ASAP.

This also applies to the available mapping software.

The Humminbird web site indicates that the Navionics GOLD, Plus, Lake maps, and Hot maps will work in that unit, but these are marine chart type maps for area where there are established marked marine channels.

The lake maps contain some of the Louisiana lakes, but it is mainly designed for the Bass circuit lakes.

I suggest that you visit a stocking Humminbird and Novanics mapping dealer and actually view these maps to see if they meet your needs.

Capt Paul,

I have some trails that were created and stored on my computer in the .gpx format. I would like to transfer those trails to my Lowrance HDS head unit. I downloaded a copy of the EasyGPS program. Any suggestions on the best way to accomplish the data transfer to my GPS Unit? Will I need to convert the file to another format? Thanks....

Response by Captain Paul

GPX formatted data
The safe way to complete the data transfer you described is to purchase a copy of the LOWRANCE data transfer program they call INSIGHT PLANNER. It is by far the easiest and safest way to make the transfer.

The . GPX file protocol is an attempt to standardize data protocol for the GPS industry, much as the old BETA and JCV were in video tapes.

The newer LOWRANCE units can accommodate the new GPX as well as the older Lowrance .USR protocol files. It will allow the user to view, edit, delete, transfer and save routes, tracks, and waypoints to and from a LOWRANCE GPS unit and a PC computer via a SPARE memory card.

You can try to simply copy the .gpx file to a spare memory card and using the menu feature of the GPS unit intergrate the new data into your current waypoint, tracks and routes file.

I don't recommend simply transferring existing tracks from one unit to another. It is MUCH, MUCH better to convert these tracks to a ROUTE if you expect to run the course over and over again. The GPS unit can guide you with headings and distances, rather than you trying to follow a dotted line on your screen.

Mapping for older units will be hard to find
~ Captain Paul's response to: ~ MuleChaser ~

As you know, the Lowrance LMS 339C is also a discontinued model and is listed as a LEGACY unit on their web site. That means that they do not service the unit any more and that accessories for it are in real short supply. The mapping for that unit was, at the time it was in production, the MAPCREATE USA TOPO series 7. If you have a copy of that software, you should be able to load it into your 339. (???)

I dont believe that the current line of mapping software will work in their older discontinued units. To verify this, call Lowrance Support at 1-800-324-1356 and ask the technician exactly what mapping software would work in that unit.

You may also check with Standard Map, (985) 898-0025,to see if their aerial view photo maps would work in that unit.

I would not invest a lot of money in accessories for the unit, including mapping, if they were not compatible with their newest line of units. Electronics, like GPS units, have a limited life span. As Lowrance is no longer servicing that unit, once it goes down, it is down for the count.

What is the best GPS for your use.
~ Captain Paul's response ~

Both of the brands you mentioned can perform as you describe, as would a Humminbird, IF they have the proper accessory mapping software.

To avoid sticker shock most of the units come only with a base map. This is what the name implies, a basic map of the entire U.S. This type of mapping gets you in the water with the GPS, but you soon see that the base map does not offer as much detail of the Louisiana marshes. It is then that you will have to come up with $200 to $300 more to have a unit that will serve your needs. So whatever unit you decide on, remember that you may have to purchase an accessory mapping for the unit.

That means that a fixed mounted unit, with a color screen of about 5 to 7 inches with the mapping software will be over your 150 gallon limit.

But to get on with your question, it is a tough question to answer. It is almost like you picking out a dress for your wife or mother. Yes the dress will cover the necessary parts, but how does it fit, where will it be used and how long do you intend to keep the outfit. You can see what I mean!

There are several units that should suit your needs WHEN LOADED with the proper accessory mapping software.

A hand held unit with an accessory or two can accommodate your needs, but the screen will be smaller than a fixed mounted unit and it would not have the depth finder option.

I would be hard pressed to recommend a specific unit. There are a lot of considerations that would affect your choice. Foremost would be the cost of the unit or rather the dollar amount you want to or can spend. Again, remember that the accessory mapping is another cost.

So, in order to at least give you a starting point, let me express some of my findings about different GPS types and styles.

Most manufacturers have a web site that comprehensively covers their line of receivers as well as the mapping software that is available.

I suggest that you begin by looking at each of these sites for an understanding of what is being offered in todays market. There are others, but I would START with the largest companies that sell hand held GPS receivers to the consumer market.

Garmin, Lowrance, and Humminbird have a very impressive line of units. These units are available for your perusal on the same web site. Check them out at Garmin @ www.garmin.com/ , Lowrance @ www.lowrance.com/ , and Humminbird.com/.

Yes, It know there are others and you may want to consider them also, but start with these brands to get an idea of what is available from the top three brands. I dont recommend considering a discontinued or Legacy product as there will usually be a shortage of accessories, including mapping software for these older units.

These current generation units when loaded with the OPTIONAL mapping software, offer a very versatile package that will more than accommodate your needs.

In addition you will have to determine the features that you want in the unit.

I can, however, offer you some pointers that may help YOU decide which one will be best for you.

A gray scale screen (not color) will be less expensive than a color one. Most units with a grey scale are older units as it is now less expensive to produce a color screen.

A smaller screen will be less expensive than a larger one.

A screen that has screen touch-controlled functions will be a great deal more expensive than a button or menu controlled unit.

Those units with a Touch Screen command area usually more expensive than button model.

Some units can utilize auto type road maps. This mapping software when used in specific units can provide an ON THE ROAD routing. This type of road and street routing can guide you to various street addresses and locations throughout the U.S. Those units that have the ability to do an ON ROAD routing generally cost more than other units that only have a AS THE CROW FLIES type of routing.

Some units cannot accept any other mapping than what is already loaded into the receiver. These units have a preloaded base map that the manufacturer believes will suit your needs. It cannot be supplemented with any other mapping. These types are less expensive than those that CAN accept additional mapping.

Some units require that a data memory card loaded with the maps you designed with your software, or that you purchased pre loaded data cards with maps. These memory cards are inserted into the receiver in order to view those maps on the units screen.

Some of the units can use an over the counter Secure Digital (SD) or Media Memory Cart (MMC) or Micro SD cards and some can ONLY use their own proprietary memory card that requires their own card reader/writer. Be sure to first consider those units that use standard type memory cards. Secure Digital (SD) and Micro SD cards area the present standard.

Some of the units CANNOT accept electronic connections. They are less expensive than those that can accept such downloads.

When considering your choices, be sure to take in to account the SUPPORT that the manufacturer offers for his units. A Support Section that offers a person to speak to about a problem is a very big plus when it comes to getting help on a specific problem. Speaking in English to a PERSON and not a machine is really a big plus in the type of support that the various companies offer.

Access the various web sites and view all of the choices you may have, then visit a stocking dealer and feel the unit in your hand. Sometimes the buttons on the unit are not quite right for a person with small or large hands or someone who is left handed. Check out the unit, the size of the screens and the general appearance and how it operates.

As for the mapping part of your question, my experience leads me to prefer maps that are based on USGS Topographical maps. Yes, I know you are looking at a marine unit, but many can accommodate topo type mapping.

Some units can accommodate aerial photo maps, such as Garmins Bird Eye and Standard Mappings photo maps for Lowrance units. Naturally those units that accommodate both Marine type NOAA charts, topographical type and aerial photo maps would be desirable.

Go to a stocking dealer and actually view the unit for a hands on appreciation of the use and features of your short list of units. Be sure to actually see what mapping is availing for the unit, viewing it in the unit of your choice.

You may be able to save some money by selecting a unit with depth / fish finder features for shallow water. You would not need one that sounds the bottom of 2000+ feet salt water. That type required a more powerful and expensive unit than one designed for 100 feet.

Narrow down your choices and then get back with me. I would be happy to discuss your options with you.

Captain Paul - GPS Info in Outside Louisiana
Hello guys,

I've got some old maps with some strange GPS coordinates on them. I was told some off shore fishermen are likely experts. So if anybody recognizes this format I'd appreciate any input you might have.

The coordinates are this:
597 699.5 North 2 983 197.8 East

These are supposed to be in Omaha right on the Mississippi river. But I can't find a way to....  Read More

Seems to be in a State Plane format
~ Captain Paul's response to: ~ Jayson 172 ~

I believe that the coordinates you listed are in a format of STATE PLANE, but I am not completely sure as I dont have a topographical map of Nebraska to be able to accurately plot the position in the state plane format. The State Plane format is a form of Universal Transverse Mercator (UTM) grid format, but stated in feet rather than meters.

Generally, the format would look something like 15T N. 44571480.0 E. 0255270.0. This position is for the center of the MISSOURI RIVER at the I-480 bridge in Omaha. It is normally called Northering ~ Easterling in zone 15T. The numbers represent meters north of the equator and east of the east~WEST boundry zones edge.

Aside from that, I dont believe that the MISSISSIPPI RIVER passes in OMAHA. You may want to double check the figures you have and if correct, plot them in the State Plane format.

Offshore platforms
~ Captain Paul's response

Please use this information as a general guide to these locations, as I cannot guarantee that the information is 100%. Some of the platforms may have been moved due to the recent trends in the offshore oil business.

With that, my information for the platforms are:


Shell Platform GC-65 A BULLWINKLE, is located in Green Canyon Leased Block 65 and is at or about 27 53.068 N. Latitude ~ 90 54.155 W. Longitude. That puts it about 114 Miles at a bearing of 232 magnetic from the entrance of the Southwest Pass of the Mississippi River.


Although you did not specifically ask for it, the Shell platform BRUTUS

Is located in GREEN CANYON Block # 158 and is at or about 27 47.742 N. Latitude ~ 90 38.824 W. Longitude

And, in the same general area


Genesis Spar is located in Green Canyon Leased Block 205 and is at or about 27 46.761 N. Latitude ~ 90 31.093 W. Longitude


Mars (Shell-MC-807-A) Located in Leased Block 807 in the Mississippi Canyon, I believe is at or about 2810.171 N. lat ~ 89 13.373 W. long, it is in over 2800 feet of water. It is about 52 miles from SW pass @ 166 magnetic AND about 57.16 miles at a bearing of 186 Magnetic from Lands End at South Pass. Mars is about 45.5 miles EAST of Thunder Horse at a bearing of 269 (mag).


Thunder Horse is located at or about 2811.452 N. Latitude ~ 88 29.735W. Longitude. It is in south west corner of Leased Block 778 of the Mississippi Canyon Area.


Ursa is at or about 28 09.242 N. Latitude ~ 89 06.213 W. Longitude. It is located in Leased block 810 of the Mississippi Canyon Area, about 7.4 miles east of the MARS platform.

Looking North and North west from these two platforms you should find MEDUSA.


The Murphy Exploration Companys Medusa Spar platform was/is in the northern part of Leased Block 582 of the Miss. Canyon. It is ABOUT 34.7 MILES at a bearing of 182 Magnetic from the South West Pass channel GONG Buoy Green # 1. It is about 21.4 miles at a bearing of 318 (mag) from the Mars Platform and about 35 miles at a bearing of 182 (Mag) from the entrance to SOUTHWEST PASS of the Mississippi River.

The MEDUSA platform is at or about 2823.559 N. Latitude ~ 8927.210 W. Longitude

Another major platform north of the Mars platform is LENA.


Lena located in Block 280 of the Mississippi Canyon area. The LEAN platform is at or about 28 39.775 N. Latitude ~ 8909.467 W. Longitude. It is about 34 miles NNE (07 Mag) from the Mars platform.


The massive BULLWINKLE -SHELL GC 65 Platform in Green Canyon Block 65 is at or about 27 53.058 N. Latitude ~ 90 54.088 W. Longitude.


The BRUTUS platform another by Shell Oil, is located in Green Canyon Leased Block 158 and is at or about 27 47.742 N. Latitude ~ 90 38.824 W. Longitude.


The Genesis production facility was/is moored in 2,600ft of water in the GREEN CANYON Leased Block 205. It is located at or about 2746.682 N ~ 090 31.068 W longitude. That position is about 93 miles at a bearing of 191 (Mag) from Belle Pass (Fourchon) WHICH IS JUST WEST OF GRAND ISLAND at the Gulf Of Mexico.


The Typhoon platform Is located in Green Canyon Block 237 and is at or about

27 43.910 N. Latitude ~ 91 06.674 W. Longitude


The Ocean Quest is in Green Canyon Block 199 and is at or about 27 45.993 N. Latitude ~ 90 47.927 W. Longitude.


I noted that there is a platform in MC 773 that is plotted at or about 2812.534 N. Latitude ~ 08844.189 W. Longitude. This platform is SPAR that is commonly called THE DEVILs TOWER. It is located near the western center of the Leased Block.

And of course, dont for get about the Mid Night Lump.


Another usually productive location is the MIDNIGHT LUMP. The area is officially named The Sackett Bank, but it is commonly called the called the Midnight Lump. It is a draw for tuna and Wahoo during certain times of the year. The Midnight Lump has become very popular in the last decade. Sometimes there are more than 100 boats a day in the active part of the season.

You will need a deepwater depth finder to actually find and see the exact location. The seabed rises about from 60+ fathoms to 33 fathoms at the lump. Picture a series of truncated cones rising from the seabed.

Gulf currents push water over the top of the lump, causing smaller bait fish to be pushed against and over the lump. Amberjack, Tuna, Marlin, Snapper, Grouper and Wahoo usually gather there to eat. Usually fishing one side of the lump is better than the other. The currents will determine which side of the lump is the better side to fish.

I believe that the approximate center of The Midnight Lump ~ The Sackett Bank, is at or about 28 38.122 N. Lat ~ 89 33.249 W. Long. The location is about 20.5 miles from Southwest Pass at a bearing of 201 (Mag) and is about 35.2 miles at a bearing of 192 magnetic from the end of the breakwater (2908.233 N. Latitude ~ 89 26. 184 W. Longitude ) at Tiger Pass.

The location is about 20.14 miles from the Southwest Pass of the Mississippi river at a position near the light house (near lands end) at a bearing of 202 (Mag), it is also about 19.36 miles at a bearing of 203 (Mag) from the GREEN #1 GONG buoy in the lower part of the SW channel.

This position is about 49.64 Miles from the RED #12 marker in Barataria Pass at a point that is between Grand Isle and Grand Terre Island.

Bring plenty of anchor line as you will need every foot of it. Most fishers suggest that you use a minimum of 600 feet of anchor line with anywhere from 10 to 30 feet of chain. The chain will greatly enhance your anchor's ability to set. Your anchor size will vary greatly, but a medium-sized vessel (23 to 28 feet) should use at least a 22-25 pound anchor. Some captains suggest an anchor point on the lump at about 250 feet deep.

The Genesis production facility is moored in 2,600ft of water in the GREEN CANYON Leased Block 205. It is located at or about 2746.682 N ~ 090 31.068 W longitude. That position is about 93 miles at a bearing of 191 (Mag) from Belle Pass (Fourchon) WHICH IS JUST WEST OF GRAND ISLAND at the Gulf Of Mexico.

I suggest that you first consider NOAA Marine Chart 1115A ~ Leased Blocks Cape St. George to the Mouth of the Mississippi River. This chart will have the leased blocks in the area of your concern. Unfortunately the Chart only covers the eastern part of the Mississippi Canyon Leased Area off the mouth of the MS River. The companion chart to the west is Chart 1116-A ~ Leased Blocks MS River to Galveston Bay. These two charts will give you all of the offshore leased block areas from the Florida panhandle to Galveston Bay.

Any authorized agent for NOAA can order or print these charts for you. Bew sure to get the most current issue of these charts.

These charts however, are in a scale of 1:456394, which is not suited for navigating the channels or the river, but will get you to the leased blocks. For a better view of the access channels select a chart with at least 1:80000 scale.

These Leased block charts show some if not all of the platforms in these blocks. I noted that there is a platform in MC 773 that is plotted at or about 2812.534 N. Latitude ~ 08844.189 W. Longitude. This platform is SPAR that is commonly called THE DEVILs TOWER. It is located near the western center of the Leased Block.

Unless otherwise specified, all positions are stated as H,DDD,MM.mmm and were determined using WGS 84 DATUM. All Headings/bearings/courses are stated in Magnetic Degrees.

Maps for Humminbird GPS
~ Captain Paul's response to: ~ Duck Shoot ~

The features of the Humminbird 698CI HD SI is a state of the art unit, however the base map called a UniMap, I believe, needs to be supplemented with one of the available accessory mapping programs.

Humminbird offers a series of maps they call LakeMaster. There is one for our region, but it is mainly for inshore freshwater fishing lakes and locations in our area. They also offer a Navionics South, but it is featured as a multi state lake maps. I dont believe that either of these products would serve your southeast Louisiana salt water marsh fishing.

Try calling the Humminbird support section at 1-800-633-1468 and see what they recommend for the salt water marsh area of Louisiana.

These supplemental mapping programs will run the better part of $150, so just dont get the first one they recommend. After getting their recommendation, go to a stocking Humminbird dealer and ask to see the recommended map(s) in Humminbird GPS unit. If they have the map, zoom in on your fishing areas and see if it gives you the detail that you want.

That way you will know what you are getting and if it will serve your needs.

The Louisiana Offshore Oil Port (LOOP) is a deepwater facility in the Gulf of Mexico near Port Fourchon, LA. It provides a DEEP WATER offloading and temporary storage services for raw petroleum products by deep water tankers. The anchor points AND the underwater pipelines that connect them together and to the shoreline are in a very restricted marine area. USE Caution whenever in the area.

There are NO specific markers that indicate the entire boundary for the LOUISIANA OFFSHORE OIL PORT, but that does not resolve you of any liability for being in the restricted area. These restrictions apply for the entire area, especially in the light of todays terrorist activity. The restrictions are vigorously enforced.

The rough center of the Louisiana Offshore Oil Port (LOOP) is located about 27 miles at a bearing of 182 Magnetic from Barataria Pass by Grand Isle, LA. and about 19 miles at a bearing of 139 Magnetic from Belle Pass at the Gulf of Mexico by Port Fourchon.

It occupies about a twelve (12) mile east to west by six (6) mile north to south area that resembles an oval. The LOOP has a series of regulations that are listed in Chapter 2 of the U.S. Coast Pilot publication. Additional restrictions are published in the USCG official NOTICE TO MARINERS that is published weekly. I strongly suggest that you get up to date information, as world events have installed a strict enforcement of the regulations.

The LOOP is in part or all of the following GRAND ISLE LEASED BLOCK AREAs: Blocks 51, 52, 53, 54, 56, 57, 58, 59, 60, 63, 64, 65, 66 and 67.

The site of the LOOP is shown on NOAA Marine Chart # 11359 ~LOOP DEEPWATER PORT, Chart 11358 ~ Barataria Bay and Approaches, and on Chart # 1116A Leased Blocks Miss River to Galveston.

I strongly suggest that get a current copy of these charts BEFORE navigating to the area.

Some of the LOOP tie up ship markers located around the area are located at the following locations:


G -1, a Horn @ 28 48.608 N. Latitude ~ 89 54.991 W. Longitude

G - 3 @ 28 50.141 N. Latitude ~ 90 02.404 W. Longitude

R - 2 @ 28 50.330 N. Latitude ~ 89 53.861 W. Longitude

Y - L-B @ 28 52.060 N. Latitude ~ 89 52.701 W. Longitude

R - 4 @ 28 54.861 N. Latitude ~ 89 57.001 ~ ~ W. Longitude

Comparing these positions to the charts, you will note that these positions are NOT joined in straight lines between the buoys. These boundary lines and buoys, however, are indicated on the charts.

Again, be sure that you know the restrictions (and penalties) for the LOOP area before venturing close to the site.

Unless otherwise specified, all positions are stated as Degrees, minutes and thousandths of minutes (DDD,MM.mmm) and were determined using WGS 84 Datum. All bearings and courses are stated in Magnetic degrees.

Transferring Google to Garmin
~ Captain Paul's response to: ~ The Truck Man ~

Ill get to the heart of your question, but first I must offer a suggestion.

I know that you requested info on how to transfer a Path or Track and certainly you can do that, but it would be far better to install the data in your new GPS unit as a ROUTE.

A Path, Track or Trail Back feature is designed to be only a TEMPORARY route that records the track in a fashion that usually replaces the first part of the track back when all of the track back memory is used. It is called a wrap method, much like a fan belt traveling around a pulley. After using all of the memory, it starts over again from the point where the memory ran out.

In order to make a permanent record of your route, you must actually make and save a ROUTE. Routes are made up from a series of waypoints which the GPS unit connects, by a straight-line course. It assumes that you can navigate from one waypoint to another to another, to another, etc., etc. In addition, some units with the proper mapping software will design the route for you using existing waterways much as an automobile GPS unit would do. I prefer to designate my own routes as the software does not know my boats requirements.

Start from your launch. Mark and save it as a waypoint, then go to the first turn that you make in your course, mark and save it as your second waypoint, then to the next course change and mark and save it, then to the next, and the next, and the next, until you reach your destination. Then go to the route function and compile these waypoints into a route. Name and save the route. You will then have a permanent (if there really is such a thing) record of your voyage that you can summon and navigate over and over again.

In navigating the route with our GPS unit, you can select the MAP, HIGHWAY or COMPASS page to guide you through the route. As you reach one waypoint the course and direction to the next one will be provided. The unit will give you the distance and courses from one waypoint to the next and even an expected time of travel or arrival. To return back to the launch from your final waypoint, simply INVERT the route and navigate the courses back to the beginning.

Using the path of track feature to steer a vessel will cause you to have an ever increasing path line on the screen which will become thicker and thicker with each use. In addition it causes you to have to constantly look at the GPS screen. The unit will only store a very small amount of different tracks, where as that unit can accommodate 100 different routes.

With that out of the way, here is the information on the how to accomplishment the data transfer.

The Garmin web site for the unit states, If you have waypoints, tracks or frequently used routes stored on another manufacturers GPS product or on a Garmin handheld device now its easier than ever to transfer those items to your new Garmin chartplotter, via industry-standard GPX software formatting. GPX is an open standard format for GPS data exchange across platforms and applications. With this easy-to-use interface technology, Garmin has taken no waypoint left behind to a whole new level of trade-up convenience.

The newer .gpx formatted data files are an effort to have one type of data file for the industry. However, some newer Garmin units require a data file to be written to a specific protocol Garmin calls an .adm file.

I dont believe that the GPS Babel program has a conversion to an .adm file format, but you can try the Babel conversion to a .gpx file format. But, dont despair, there is a way.

But, before actually trying to write a file from a Garmin Data Transfer program to a spare and let me repeat, a SPARE, data card you must first place the memory card in the GPS unit and turn the unit on. I suggest that you do any function with the unit, simply changing a screen page will do. This procedure causes the GPS unit to install a code on the card that is recognized by the Garmin program in your computer and later again by the GPS unit. Without doing so, the GPS unit will not accept the data information. This is a must in trying to do data transfers. Trying to use an existing map data card for the transfer could over write existing map images thusly ruining the card.

First, save the Google Earth data to a file, I suggest saving it in the Google .XML format. I save my data to a folder I named GPS then in a sub folder for each of the different areas I fish and hunt.

Then, using one of Garmins data transfer programs, transfer the data first into the data program then onto a spare data card.

Garmin offers a free data transfer download program on their web site called HOME PORT. I strongly recommend that you install the program in your computer. It will save you time and effort in doing this and future transfers to and from the GPS unit and your computer. It will allow you to back up all of the waypoints, routes and tacks in your GPS unit to a file in your computer or on a thumb drive. They also provide a program for land use called BASE CAMP. Actually either will work but the Home Port program is designed for marine type units. Both are available from the Garmin web site at https://buy.garmin.com/en-US/US/prod64242.html

It is available for both Windows and Mac systems. As said, it is a free download. If you own a Garmin unit, you should have one of these two data transfer programs. This program allows you to install a Google file into the program then onto a data card as an .adm file.

Once installed in the Garmin program, click on the FILE icon then the Import from window to the file folder where you saved the Google .XLM file.

Once doing so all of Google data will appear in the Home Port program.

Place the spare memory card in your card reader. Then select the small icon at the top left of the screen that indicates two small GPS units. One is send to device and the other is receive from. Select the transfer to option and window will show the GPS model and serial number that was written on the card. In that window you will have an option of transferring it directly to the unit, or to the spare data card. If you have the unit connected directly to your computer select that option. If it is not, select the option that writes it to the data card.

One word of caution, when using the settings in your GPS unit as compared to the options in the Google Earth program be sure that the Datum agrees.

Let me explain. My information is that Google Earth uses a EGM96 Geoid in displaying their Google Earth programs. I believe that the Google Earth images are corrected to use WGS 84 datum. So if that is the datum that you use in your GPS unit, simply enter the Google coordinates into your unit. Be sure to check the position format to be sure that they also agree. You can either change the Position Format (Location) in your GPS unit or you can change the Google Earth display by going to the TOOLS/Options link at the top of the program and select what ever position format you normally use. Be sure that they agree.

So, if you are using your GPS unit in a relative flat area, such as Louisiana, or any sea level environment, I would assume that the figures are fairly accurate. However, if you are using the WAAS feature in your GPS unit in order to get the 3 meter accuracy via the differential system, your position via Google may only be to a position accuracy of 20 meters. Your WAAS activated GPS unit will produce a more accurate position fix on the actual position.

I would use the Google info but use it with suspect. When you get to the actual location you should use your WAAS activated GPS unit to refine the actual or true position.
