Geeez, Don't use 3/4in marine ply. It's to heavy on the wallet and the boat.
3/8in is plenty.
If I was doing it, I'd use the 3/8in BC put it together temp. Take it apart and use the panel's as pattern's for Nidacore or if it had a bunch of curves 3/8in Divenacell.
I used 3/8in Divenacell here for the sides.
