having read the transom-material debates in various forums re foam core materials vs. marine plywood vs. poor old seacast pun intended , i concluded that marine plywood is clearly favored by at least a plurality of the pros here as being 'tried and true' and having known qualities, despite it's achilles heel susceptibility to rot . even so
i have a wooldridge alaskan ii and the marine plywood floor is 12 years old and has the factory rubber covering and is in good shape but when i pulled the floor last year it was super heavy water in it . i like the sound dampening of the wood, but think about diamond plate, and have looked at the composite that is light and has good sound dampening but is not as tough as diamond plate
re: composite or marine grade ply wood? composite ie. reinforced plastic is heavier and does not have the structural strength of plywood ie. a wood laminate composite . the coosa composite is foam with reinforcing and is lighter than plywood but does not have its strength. i would prefer a marine grade plywood that was completely covered
it takes tools and the makings for a fiberglass composite to fiberglass a plywood boat. it involves some elements of carpentry, because you have to be able to measure how much boat you're going to cover. on top of that, you have to figure out how much fiberglass you'll need to cover it, since eight layers of
epoxies are in a similar realm to vinylesters when it comes to performance in a marine composite, though you wont find many production boats using it. its more fickle to use and more sensitive to heat, and some workers are allergic to it. however, if a custom boat is what you seek, its a fine alternative.
i like to build small plywood skiffs in for my own use, not for resale. i have no experience with composite panels but would like some direction from experienced peeps about what would they use to replace plywood on a skiff build? most of these boat use 1/4' or 1/2 ' and are less than 10 or 15'.

i saw a composite deck today at a customers house and i was thinking that it would be the ultimate boat floor instead of plywood. has anyone tried it or have any pro's or con's about it.
thermo-lite board is the ideal alternative or replacement for plywood and wood products. thermo-lite board is strong, light weight, non-absorbent, and almost indestructible. it's a unique product that is sustainable for many applications in the marine, ground transportation, and building industries.
the differences in building methods between plywood composite and foam sandwich result from the difference in stiffness between the two materials. plywood is stiff and will require less molds. in plywood cored composite, the frames and bulkheads can often be used as molds.
hi everybody, in his book 'the nature of boats', dave gerr explains that for a given weight, wood is much better than conventional materials. for instance, he lists e-glass at 158 psi/ lbs/cuft in tensile strength versus weight and douglas fir at 388.
the coosa products are more expensive than marine plywood but then i don't have to go through the hoops of making sure i have all edges, holes, etc sealed. say i forget to predrill a hole before i install it. but for the cost of composite vs. the marine grade, and the ease of working with it, i know i'd be using the plywood. you'll get
