I think it really depends on each boat. I have seen boats turned around in a day and I have seen other boats take a few days. I would rather see the guys take their time and get everything correct in a 2-3 day turn around(so 12-16 billable hours depending on what goes in the boat) than to see them scramble to get a boat out in one day. If they rush to get it out in one day you might end up having to come back the first full lake day to get a few things tweaked. With all mechanics. You are going to have some that are just pure bad A$$'s and they can knock stuff out in 1/2 the time with 100% better workmanship than other guys. I always hope that is the guy that draws my boat prep..
