We have done private charters for many years while in sxm.. we always charter with Ian Martin.. it is the very best day of our vacation. The boat is beautiful , plenty of shade or sun, the food is great the crew is awesome you can find him on trip advisor and his website www.stmaartencharters.com
also on face book https://www.facebook.com/#!/AdventureSportsSailing?fref=ts
also reviews on pirates of sxm.. I would highly recommend him and we have chartered so many years (14) He will start off as the captain but will be your friend by the end of the charter..includes drinks and food you can snorkle, fish, whatever you would like to do . We are going back in November and again will charter with Ian.. will do a day over to anquilla..
