Come on guys, what did you think, too weak! I use it on a motor boat until it breaks, but then again I haven't taken it through rough waves yet. I doubt it will withstand the heeling of a sailboat. The closure at the back seams seems reasonable, but the one at the front folds easily and can break or come loose with very little upward force or tearing force. Does not match the quality of the Porta Potti device itself.
