Here in Canada the rules for passenger carrying are .really tough Probably next to impossible to do in wood any more.If you have a long term plans check closely with your authorities. Retro fitting two or three watertight bulkheads and non flamable interior (for starters
) can be a lot of expense. You follow the same list as a much larger (2,,300 ton ferry).I wish you all good fortune. There is nothing like a wooden vessel for matching your heartbeat to an ocean swell.
