I was just reminiscing about when I was at university. We had a kayak in the club that started out as a low volume stunt boat, but someone decided to make it even more low volume after it had an accident. They heated up and pushed in the front end to create a concave bow deck, and also gave it an almost flat back deck. There was barely space for your legs, and it almost looked like it had been vacuum formed over the user. We called it "The Flid" as you couldn't walk very well after using it, we'd probably all be kicked out for calling it that in this day and age heh. It was shit for everything but pirouetting on flat water, but it was fun as hell for that.
