I just picked up an Epoch 50AH Marine battery. It has all the bells and whistles. I'll keep the thread informed as I install it in my 1436 Alumacraft. 12V 50Ah Marine Battery - Lithium Trolling Motor Battery

I used the FRP/polystyrene composite from my thread where you asked a question. It is flush with the middle seat and runs to the bottom of the lip of the front seat/deck. So my deck is on plane with the middle seat, giving me the longest run of deck that is flat.

This is how I transferred vertical loads to the seat. I trimmed the. 2" angle height. This was riveted to the seat lip. I then used angle stock to accomplish what LDUBS is illustrating. It is solid, and pretty fast to do.

Some really easy storage to access is under the front deck of your boat. If it is similar to my Alumacraft, it is open, and not filled with foam. A quick Amazon hatch and you have an easily accessible, pretty dry area. I keep my paperwork, and bags of plastics in this area...

I think that it could work well with some additional supporting structure. My goal was to have as little supporting structure underneath as I could get away with. It is all built with 2" angle of 1/16" aluminum from Lowes. Very light! I actually believe I have more than double what I need...

Ok guys and gals. It was a long time getting on the water, but well worth it. The new casting deck works fantastic, and is solid as a rock. This is my first bass on the upgraded Alumacraft 1436. Topwater off a deep point! A great way to start the season. I only lost about half a mile an...

I used medium epoxy when I made up some frp and polystyrene foam board composite. I am thinking that for this application you may want to use some 3M auto body panel adhesive. It will never let go, and comes in a cartridge for easy application. Not especially cheap, but it is all business. I...

A bit more progress.

Yes, it is there under the Hydro-turf.

Well, a lot of time has passed, but I am nearing completion of the Jon boat overhaul. New removable lights, new trolling motor and front mount, new casting deck and center section decking and Hydro-Turf deck covering. I'll be covering the bench seats with it as well. I am adding a pedestal...

LOL, I wish I'd known about this ACRE board. It weighs about the same as my laminate and costs under $150 for a 1/2" 4'x8' sheet. It would be nice to know what weight it would support. Still, thanks for adding that to the thread. Good info.

I did the support for the deck today. Another view. And a cross section.

Price a 4x4 finished piece. One 4x8 FRP $41.00 One 4x4 pink foam $10.00. Epoxy 72 ounces $55.00. $106.00 for 16 square feet = $6.62/ft sq. Weight is 1.6 pounds per square foot. A fair amount of labor. Worth it to me, as my Jon will have a maintenance free casting deck, but will not have gained...

I forgot to add, the panel weighs 20.1.lbs It is about 12 square feet. I mixed 36 ounces of epoxy for each side lamination. A total of 72 ounces for this deck. There was some extra in each batch, and some that oozed out the laminations. I spread a coat on the foam, then spread a coat on the...

Finally got to work on this today. I used a 4" metal cutoff disc in a grinder to trim the edges of the glued sheets. I then used 80 grit belt sander to finish the edges. I'll put a final coat of epoxy on these sanded edges before final installation. TEST! Supported only on 3 sides. I can...

Five horsepower on a 1436 flat bottom jon boat got me about 12.5 mph. Just kinda on plane. Just one person, virtually no mods. I too second the recommendation to find a 48" wide if you are fishing. I did some prop tuning and added a 6hp carb. Those changes got me about two more mph. Amazing...

A couple of processes to complete before mixing the epoxy. First, I made a disposable tool to cover the foam surfaces with small holes. This should help give the epoxy some teeth, seeing as the sheer strength of the foam/epoxy bond is probably the weakest part of the composite. The second prep...

I made some good progress on the front deck. The outline of the aluminum framework is completed as well as trimming the pink foam board to fit. Unfortunately, the weather is turning very cold so I won't be able to make up the sandwich composite till it warms up some. My epoxy hardener was...

Thanks fellas. Yes, the gorilla glue type adhesives might just do the trick. The hard thing with them is keeping things flat during cure, as they exert a huge amount of pressure as they kick off. I guess they have that tamed already if it is designed to use on paneling. I don't think the...

I am sandwiching pink formular 150 insulation board between two sheets of FRP. Tonight I weighed my 1' x 2' test board. The weight is 1.3 pounds per square foot. The weight is pretty good. Coosa board is 1 pound per square foot. 1/2" marine plywood is 1.6 pounds per square foot. The hoped...
