DIY - and truly homemade (rather garden-made) inflatable boat, welded from PVC sheets, using an old German Tummler engine. After the first "dry" design, we found the engine was too weak for a boat with plastic bottom, hence we cut it on the spot to form a catamaran design, which was finally usable for up to 4 people, and could be even for more if speed was of no issue...
