They are strong but cost prohibitive and I believe a little too stiff for a backbone in a fiberglass boat. Besides if it has a center stringer, you will need a piece that is at least 12" wide. That may be a tall order ($$$) in the hardwoods. Then there are composites. More money. If you need longer than an 8' run you make a nice scarf joint in the plywood and reinforce with glass.
What glass did you buy? and what is your layup schedule?
I bought West Systems 105 and 206 the stringer was just plain lumber I swear it is pine it was really cheap wood the deck was 4 by 4 plywood squares.

Blu Lunch:

Did you pop the top or cut out the deck? I did a search for earlier posts but couldn't find anything. Any photos?

They could have used pine, it was not a hardwood that is certain. My floor was plywood squares layed in place while the liner was probably still in the mold. The forewardmost plywood bulkhead in my center console was only tabbed in place. They sprayed the bare wood with gelcoat to make it look better to the casual observer. The reason Marine Plywood is recommended by Skool and others is because it is supposed to have less voids in the interior plys, in theory a void is a starting point for osmosis and the beginning of rot. If Wellcraft had sealed their wood better it would probably not need so much work today. I like the idea of epoxy, I just have started to experiment with the stuff. Best of luck.

BTW- I am no expert, just re-built a boat or two that are still around. The plywood is stuff I stock here at the lumber yard for anyone that is local and would like some. It isn't $45/sheet though Skool. More like $60 for 3/4 Marine Tech PT KDAT one side sanded. It can be glassed without a problem even though it is PRESSURE TREATED, due to the fact that it was dried in a kiln after.

Thanks for the info Blu Lunch & Schools. Very impressive jobs.

Schools - it appears that you either find and restore classics for a living, or you do that as a serious hobby. What fun that must be.

One question: how did you both cut out the decks? With a rotary saw?

When I cut my gunnel trim out(the 7'ish peice that holds the gunnel rod rack on the F-20) I noticed the plywood squares also.

Just curious if anyone has any idea on why they did this??????? Seems really cheap and bound to fail. I replaced mine with starboard.

My dad's guess is that they got it through some kind of flooring company as left over peices,blanks,templates,etc..
