I doubt weak plywood was the (main) problem. From what you
described sounds like the underlying structure (frames,
bottom batens, keel) gave out. Covering all
frames and longitudinals with fiberglass tape will
add some strength.
Hitting a wake at 85mph is a brutal force -- more
like a crash!! I hate to do that with my 17'
Glaspar running 35mph!
Did you build your Thunderbolt? What type of wood
did you use for the frames, longitudinals and
plywood? You must have one heck of a motor to do
85mph!!!
I'm currently building a Thunderbolt. The hull
is completed and currently working on the top
decking and interrior. I used okoume plywood,
mohagany frames and sitka spruce stringers. Planning
on using a stock chevy 350.
