On one of the financial shows they featured a Kayak manufacturer looking for venture capital. The company demo'ed a folding kayak that had what I would call a membrane skin and some framework made out of, I presume, high tech fiberglass. It all folded into a square which could fit on virtually any boat. It was nearly flat. I don't know if it had a keel, its length, width or weight. I don't even like kayaks but it seemed like something useful for gunk holing, touring the local anchorage or just getting a bit of exercise. I didn't catch the name of the company. I think the money guys, or gals, shot him down as the market isn't big enough.
