I have a few 4 x 8 foot, 5/8" sheets of Skidguard marine grade plywood that would make great floor or deck material for your raft or pontoon boat project. This stuff can be hard to get even though the make it locally, they require a minimum order of 48 sheets. I will sell some for $80 a sheet, well below our cost for the material. I don't have any photos available immediately but it is black on one side and light brown/tan on the other. Available for pickup in North Bend.
