After the successful rollover of my 1955 15ft Cavalier and stripping of the old plywood bottom (as pictured) I have a few questions regarding the replacement material I should be using.
The keel and frames are in nice condition considering they are 57 years old!!
I hope I hold up that well in 23 years time!!
1.) The amazing packet of information sent to me by the Mariners Museum has an advert stating "full length marine-plywood panel construction" out of interest does this mean that the original bottom would have been comprised of full length plywood sheets bow to stern? Or did that simply mean it was comprised of plywood only? The bottom I just stripped off had a join on both sides on the 3rd frame from the bow but it was not the original bottom.

2.) The packet from Mariners Museum also advised that the original bottom was 5/16" Fir Plywood (as pictured). Now after going to Condon Lumber in White Plains NY today (what an amazing place) they only sell 5/16" Plywood in 4'x8' sheets and considering that I need 10' to get to the frame where the bottom was previously joined the 5/16" is not an option which leads to my question. As it looks like I will need to use 3/8" in 4'x10'or12' has anyone used 3/8" (9mm) material in place of the original 5/16" (8mm) and did it present a problem at the bow where it needs to curve?

3.) Should I use Mahogany Occume (MFC) plywood or Mahogany - Occume (Bruynzeel Holland) considering this boat is going to be used in mostly fresh water and will spend a maximum of 7 days straight in the water at the lake house.
Maybe I am way off in which case please put me straight!!
