Boat structures 101

[Jeff79Sceptre]

I'll have to agree with Fas. When I bought the 23 last year I replaced the deck with 3/4 ply and epoxy. Then I replaced the fuel tank platform with 1/2 coosa. I made my deck in 1 piece then dropped it in. It was HEAVY. After putting the coosa in for the new tank it flexed. So I asked a few questions on here and my schedule wasn't correct. Cut it out, more 1708 and tabbed it back in. Super strong and light weight was the end result. Now I'm on my transom replacement. Coosa is what I'm going with because of my prior experience with the fuel tank platform. I'm upset with the deck in the boat and I may next winter hack it out and redo with either coosa or core cell. I don't know anything about the latter but I'll keep watching this post. Very informative!
