: Carl, I fyou have not yet seen Ray Jardine's log of how he constructed
: several kayaks, including one from foam and glass, take a look at them.

: You should like them, and they should be good info sources for your class, as
: well.

: Or, it could break in such a way that the first paddler is trapped in the
: cockpit, while the boat folds up and pinches him in place. Keep plenty of
: people around for a safety crew, and do your test launches in very shallow
: water (5 to 6 inches deep). Once you have some feeling for how strong, or
: flimsy, the craft is, you can head out to deeper water and more
: challenging tests, or head back to the shop for mre reinforcement.

: Keep it safe and enjoy the design and building process.

Thanks for the link - I'm looking over the Jardine build now - and thanks to Aaron for the foam baidarka link below - I'd seen that before, but forgot about it. And no worries about safety - there's a chase Zodiac, pfds, radios and boathouse manager keeping an eye on everything that happens at the waterfront here. You can imagine putting 20 students into Lasers and letting them head out into LI Sound through a busy shipping channel.
