I'm building a boat in South London - it's a Farrier F-33 folding trimaran (here's the designers website). It's 10m long, 7m wide when unfolded and when done will weigh about 1500kg. It will be able to cross oceans, if I can ever get through the traffic.
Inside is my sparsely updated blog. There are general rambings here, but really it's all about the boat.
