I am of the opinion that 3/8 plywood is MUCH stiffer than 1/4,
stronger and not a lot heavier..
I find a full 3/8 plywood deck well supported works well..When I
design a deck that will be walked on I think of picture frames or 4
sides boxes 12 inches wide by 12 inches long by 3 inches deep..Bracing
like that well supported then covered with 3/8 ply is very strong..I
think that a brace every 12 inches is my standard.. Ribs once were set
that close but on some boats I open them up to 16 inches.. However,
Stitch and glue boats don't fit that rule..
My next boat will have a 3/8 plywood bottom, 3/8 decks and maybe 3/8
all over.. BUT since it's gonna be a 12 feet long scow maybe I will
make the sides out of 1/4 ext ply...BUT the fact is I am not sure the
weight difference is worth all the trouble of using two thicknesses of
