Thanks for the replies--I have decided to put cocobolo pad-eyes for the criss-cross bungee deck lines fore and aft, following some pictures Etienne Muller had posted on his site. The boat is really a double-paddle canoe, and I'm sure not going to try to roll it with that huge cockpit opening. I plan to row it as both a single and a double, so I do still have to sort out seats--placement, trim, and how to configure it for conversion from two paddlers to one. Any suggestions on that front?
