[C320-list] Interesting discovery on cabin floor

Here’s a photo of my 1996 sole

https://ibb.co/Rv69KZK

It does indeed seem to be made of two layers of about 1/4 in and 3/8 in but they are bonded firmly together

It was the same on my previous C320 - also 1996

Note the small void in the ply

I have had no problems with the sole generally other than around base of mast support post where it had rotted and needed to make a new piece

I used teak veneer then routed out grooves for the holly strips. All epoxied in place

But that was just one board  about 14in x 8in. If I was doing the entire sole I’d buy teal and holly faced ply and save myself the trouble!

However, I'll say that i've already refinished my floor once. And it looks like the substrate Catalina used on my boat is pretty good stuff. It's pretty thick and it has a water resistant plastic laminate of some kind applied to the underside. and it's WAY thicker than quarter inch. More like half inch, at least. I can see the markings on the underside where I'm fairly certain it was done at the factory because it has my hull number marked on it.
