As an amateur boat builder I'll hazard a guess that the spring is wound - steam bent.
Especially with the right kind of green wood, steamed for the right amount of time in a good steam box, you can tie it in a knot. For a little while anyway, until it cools off. I steam bent all the frames in a canoe I made. 14' canoe, 20lb total weight.
For stuff I've built I just have the canoe (Platt Monfort design, called the Snowshoe 14), an 8' Bolger designed Nymph pram with leeboard and sail rig and a partially completed Kulzinski (sp?) designed sheet plywood (3mm mahogany ply) kayak. I built one other sheet ply kayak, but ended up giving it to a friend as it was too small for me - my legs fell asleep paddling it.
I've also got a plastic kayak - a Necky Narpa. Love it - it's indistructable. No need to take care when getting into the shallows.
I picked up a used KLR650 to add to my fleet and replace my old 93 DR650. I got a really good deal from the original owner up in San Francisco. I purchased this for a couple of reasons... First... Me and my son want to do some adventure riding. He's going to pick up a KLR himself and sort it...
