Re: on sail boats charters ...
Anybody that has a boat that big has got to have it docked at a pier or at a marina. Ask any big boat owner.
There are tons of sail boats around. Unfortunately, the one guy I knew that ran sailboat charters from La Romana out to the islands had a motorcycle accident on Las Americas and had to give it all up about 8 months ago (he's OK now).
Contact the guy at the link I gave you. I'm sure he can put you in touch with someone.
