Build a small pontoon boat out of plywood. Easy to follow visual steps, but for liability issues no plans are available, but it's not difficult to figure out. All laid out from 4x8 plywood.
when building pontoon boats, always build so that each pontoon can support the entire weight of the boat, gear and people on board. If not, in rough conditions you can capsize.
I have designed a fold-up pontoon boat. It would have a platform of about 8’ wide by 7 feet long, and it could easily fit into the back of a pickup (folded). Once removed from the pickup bed, the owner “unfolds” it. The pontoons also unfold to create (2) 16” wide x 12” tall by 14’ long pontoons. A very unique feature with my design is that the pontoons are mounted at a 45º angle out to the deck, setting them outward about a foot each, thereby giving the pontoons about a 10’ wide stance.
@@near--zeroI'm going to add water tight bulkheads with fiberglass so each pontoon has compartments. If one takes on water it will be isolated. Inspection ports need to be added as well.
Awesome boat ! Can you tell us when the plans might become available on PDF or booklet form for mailing and your approx cost and time of construction ? - Thanks Great Job and want to make one if it is within a reasonable cost versus buying a already constructed pontoon.
Great build would like to build one can you please give a little more information like how you sealed then and a material and how to calculate the size to carry I need to carry apx 700lb great job
Hux, This is a concept drawing, but that being said the construction is pretty straight forward. I tried to maximize the build using 4x8 sheets of plywood. All contact points would be screwed and glued. All interior contact surfaces would be fillet's using an epoxy micro bead (like putty), likewise all countersunk screw holes putty covered as well. Interior seams require fiberglass tape and two part resin application. Note micro bead fillets infer that they curved, fiber glassing does not like sharp corners. As for the exterior you have to radius all edges, micro bead in 90 degree contact points and apply fiber glass tape and resin. After dried apply fiber glass cloth and resin over each pontoon. (a ton of info on plywood boat building out there) As for sealing there are many 2 part epoxy paints out there. I'll do my best to explain buoyancy next.
The formula I used was Length x Width x Height x % submersion (pontoons out of the water) x 62.4 (weight of 1 cubic ft. of fresh water) So pontoons are 10' long, but 2' are the bow so lets say 8'L x 2'W x 1.5'H x 2 pontoons = 48 x 50% (half in water) = 24 x 62.4 = 1497 lbs. So including the weight of the pontoon boat and everything and everyone on board you should be OK shooting for 700 lbs. I'm no math wizard so perhaps someone can check my calculations.
Hi i really like this mini pontoon boat such an awesome idea!! My son and I would love to make one. How can we get the plans for this size of pieces and thickness of the different parts?
The stringers are 3/4 as well as the deck and stern. The sides and bottoms are 1/2 inch. The runners on the bottom are any hardwood 3/4 x 2" Keep in touch. Chazz
Never got to build this concept yet. Still working on my shop. Hopefully this winter. You can tell by my publishing dates I do design in the winter, that was before I had my shop. So....I look forward to building this winter instead.
@@elhazfishing9960 I had to look up Dynel, never heard of it before. It seems a bit fussy to apply, but looks like there are some advantages. Also might require several more hands to apply. Due to a injury 40 years ago I only have one good hand to work with. Thank you for turning me on to this product, Chazz
@@workinghand5768 I saw it on another video. You pretty much wrap the whole bottom side in it and go from there. Anyway, can not wait to see how your pontoon turns out. I am working on plans off of your video for something a little bigger and see if I can not put storage in the pontoons for rods and what not.
Well go build it and get back with us. I would like a short rundown video of the build with first voyage documented. I'll be waiting for you, but I expect this within 18 months or so. I feel that is more than enough time, so no 12 year bullsh** lol
