Yes to the survey, by all means.
As to the sails, he said that his research uncovered the fact that sail lofts like North Sails (SF Bay area shop) and others all take the measurements, quote a price and then send the order to an Asian sailmaker who manufactures them all for them, while they add on thousands for the brand and logo sewn on the sail.. This wouldn't surprise me, as it's common place in many consumer electronics, appliances, etc. As to WHY the luff tapes weren't sewn in originally, it could have to do with him switching to a Profurl furling system which had different luff requirements. He said that the head sails also have a foam leech that aids in furling leaving a more oval shape than the tight, round shape on most furled sails. Whatever..
He seems pretty forthright, has been sailing for over 30 years (he claims) and is a dentist, so he ain't hurting for money.. My goal would be to survey it and see if I can steal it from him for around $25K or so. Nice boat though..
Thanks for all your great help..
