True on all counts about UHMW. It actually is a benefit that is doesnt seal. This allows full drainage after use. I did glass the entire boat, but I was building a new boat, so moisture was not an issue. I did the System Three full epoxy encapsulation with cloth. I can't imagine that you couldn't put your boat upside down in the garage for a couple weeks with some mild heat under it to dry it out. I'm not a woodworking expert, but I wouldn't finish the boat without sealing everything with epoxy so that you ensure you never deal with this again. All these reasons are why I sold my wood boat. The epoxy encapsulated floor would flex under load, and on a rainy day take in some water. I found the maintenance just too much for my liking. Even kept in a warm garage it still needed routine maintenance. It's a labor of love.
