72 20' new deck

[Rbphipper]

Thank you Don and Jorge for your experience. Based on what you said, I'm going to cut out that remaining skin, and go with 1/2" coosa epoxied to the 2" ledger all around. I chose 1/2" so I can use the scrap as spacers on the stringers. That's the depth of the old floor. I'm going to keep the scuppers where they are and just plug them as I'll be trailering this boat. I was concerned about the whole deck raising to 2.5" anyway, because I'm a new granddaddy twice with boys who I hope love to fish, and the floor height to the cap is a little worrisome if they decide to lean over for that one second.

I did 1/2" coosa on my deck, at the span over the fuel tank(~24") I cut up scraps and added strips of the 1/2" coosa to give it extra rigidity. It's rock solid everywhere. Rather than paying the extra for 3/4".

1/2" on my 18. Solid as a rock.
