You might want to consider a charter from Barefoot Yacht Charters out of St. Vincent. The entire team at Barefoot is exceptional, with incredible knowledge of the Grenadines, and helpful in so many ways. We have been booking our charters with Barefoot for eight years, and have made great friends and would highly recommend their services. The have a wonderful location in Blue Lagoon, a great restaurant for meals, and lovely rooms for stay before and after your charter. They have several large catamarans for you to choose from and certain they will make your charter great.
