easier to work with than glass. Either paint it or leave it natural.

This is going to be a large, say 12x12 rigid dinghy that will support
a solar panel farm.

Wood is heavy, wood will rot, and wood is weak when compared to a foam
core complete with knitted glass and epoxy skins.

The above structure would add a lot of weight high above the water
line if made of wood.

Just for reference, a 4x8x1/2 sheet of plywood weighs about 42#, while
a 4x8x3/4 sheet of Divinycell weighs about 16#-17#.
