I am trying to redo the interior of my boat and have a question about the padding along the side and back of the boat. What is there now has approximately 3/8 inch plywood, foam padding and then the vinyl material. The wood on the starboard side is too rotten to reuse. But it is bent at a 90 degree angle within just a few inches. How do you get plywood to bend like this? I am thinking it would be easier to use 1/4 inch or smaller. Any other ideas?
