For the lacings to the hull I won't use rings, but a 6 mm alu rod in the sleeve. Probably stronger than rings, and less fuss.
The shop I bought the materials warned me the last ring on the side of the trampoline is loaded a lot and has a tendency to fail. That's why I strenghtened it a bit.
Apart from the tiller and some small jobs the boat is ready. I still have to take care of the rig and the raising pole + wires, though. I can't finish that because I'm still waiting for Erik Precourt to fabricate the 8mm version of his Olivier Link which I plan to use for the shrouds. Erik mailed me he would be working on the links this week, so I hope there will be some white smoke at the end of the week.
