Fair enough. Definetly sound like an expensive panel for a boat that probly is what mid 90s? How long before that panel outlasts the rest lol

He might need a lesson on foam core bonding. That's not where I come in

I think its probably like a 1998-02 somewhere in that range. The core was probably wet for 10 of the 25 years. Takes a long time to break down. Basically rebuild with foam is same as ply but you get more stiffness as you can go thicker on the panel if there is room. Ship happens I'm pretty sure I know you through my buddy Chris. We then both know the master of glass .....Stuart....

Yeah Stuart is the master of the universe in glass. Yeah I know Chris, very well, and his boat. I'll be staring at it when I walk into my shop tomorrow haha.

So hey if foam core was layed up, don't you need a similar thickness layer of glass on both sides? Like a push pull effect? Isn't that where it gets the stiffness? Kinda like honeycomb carbon fiber layups?

Not Coosa that's totally overkill, good for stringers, transoms and bulkheads. I'm talking core cell, divinicell or other pcv foam cores. 2-6# per cubic foot. Epoxy is great but it's well over 100$ a gallon right now. Put the $$$ into the foam. Might be like $250 for the core material and a couple gallons of poly resin.

Not sure if George at ultra lux plastics is around but he always had great deals on foam core. Right near the river rock casino.

If you are doing this yourself you are already saving so much $$$ you can afford to use better materials. Lots of ways to do this one all will last 15 years or more just depends on your preferences.

Thanks Mike.. Will give you a call

The boat is a 1997 232.. still in pretty good shape.. have kept up on the maintence since I have owned her...

Top skin is in compression, bottom skin is in tension. Usually the top ends up being thicker becuase you need more durability and impact resistance. You can get away with a single layer of 1708 on the bottom if you really wanted.
