Duncan - I am in a similar situation in that I would like to build something out of wood from scratch. I have found it difficult to get information as well so I have started designing my own shell. What have you managed to find, have you started anything?
Duncan, due to an email wipeout I have lost your address - did you locate suitable plans? Are you building anything?
And did you notice this rather fast-looking wooden shell design by Graeme King at the Wooden Boat Store site?
