thanks everyone for your advice. it's a sailaway (with insulation, battening, basic floor) and engine that we'd ordered. we were hoping to have a month to work solidly on it before studying when we would have to work on it more gradually. we did go up to meet dave and see his boats. it has been lack of contact from him, pushing back dates and a reluctance to sign any kind of contract that has made us worry. i think his boats are good, that's what i've read elsewhere. i also think he's probably a fine builder for someone with a more normal time scale. i know we were asking a lot - but this is what he verbally promised was possible in july, so we were going with what he said.
