I wonder what the going rate is for the plastic for a Yost folding boat is these days. I live on the north end of the LA (Santa Clarita) I check at a plastic supply house and the told me it would be $300.00 for a 4 x 8 sheet, had to buy the whole sheet. He was helpful, said he thought it would be about the same at a big box store. He also indicated there was a special formulation for exposure to water and salt water that he highly recommended, same price and more or less the same stuff.

anyone got half a sheet to sell?
Meanwhile I am slowly making progress on my S&G, would be faster if I would just go ahead and make the mistakes and then ask for help to fix it. Perfectionism really slows the build.
thanks, John
