Building a pontoon boat. Need to join numerous foam billets and cover them with something to reduce surface area. What would you do? Great stuff? EA40? Boat epoxy? Fiberglass tape? Pontoons are each 16’x1’x2’.

I have numerous billets of differing sizes. Thinking of joining them with dowels and epoxy and filling gaps with great stuff. Bonus question… Am I retarded? If so, why?

Personally, I'd use aluminum and form it into a long tube. Weld the seams using a gas tungsten arc welder. Then cut the tubes in half to get two tubes. Then you'll have a good platform to attach a deck. The tubes will have the lowest friction coefficient.

Otherwise, just use polypropylene rope and fasten your flotation devices together like Gilligan's Island would do.

Good luck.

Gotta use what I have. Though I like the idea. And all I have is a stick welder that I use like a 6 year old.

Aluminum welding is not in your future...
