I subscribed to Wooden Boat Magazine for years but now pick up a copy a couple times a year. I've also been searching for long marine plywood for a surf dory. The demand has apparently gone because I can't find a sheet longer than 8' in Louisiana. Last nearby place to have it was apparently in Raceland, LA but they must be out of business. Until recently, two local lumber yards could special order marine plywood up to 24' length. Good luck, that's why I suggested the forum instead of the magazine, I've tried every number in the advertisement section.

I found a good place to buy marine plywood close by. Its called World Panel Products in Winsor, N.C. Talked with Al, who works there and was really helpful in selecting the right plywood for my project. I'll probley make a trip there this week.
