Marine Grade Plywood?
Perhaps I''ve not been looking in the right place... but what I''ve found so far is that I can get decent quality exterior grade plywood 4''x 8'' 1/4 inch thickness for about $10 a sheet.
So far, the cheapest, bottom of the line marine grade ply in the same thickness has been $62 per sheet then you''d have to add substantial shipping costs too.
Also, I''ll note that I''ve found many descriptions of successful use of exterior grade plywood in home made boats of all shapes and sizes.
At this point, I''m inclined heavily toward the exterior grade plywood due to cost concerns... also, the use of non-marine ply doesn''t seem to have slowed many others down.
Perhaps I will yet find an inexpensive source for marine ply.
What price per sheet of 1/4 inch thickness should one expect to pay? Perhaps I''ve only hit high-priced websites?
