Measure twice, cut once. Sage advice when you take a chainsaw to a wooden boat. It is a peculiar thing to do really. Cut a boat in half. Everything about the structure is designed to float on water. And I go and do the opposite. Cut the thing in half with a complete disregard for buoyancy.
During this stage we really found out what we were dealing with. The paint was all stripped off, loose parts removed, sharp edges smoothed and the first boat was cut in half.
So far things are looking pretty good. The boat is free from rot and outer surface is just about ready for a coat of paint. Next step is to make them steady on their (new) feet and plan the seats.
