About Us

Mainsail was founded by Kevin and Carol Jonas.

Kevin and Carol booked their first Caribbean private yacht charter in 1996 and were hooked! They did three more in quick succession and listened when one of their charter captains told them they should get into the charter industry and become Caribbean yacht vacation brokers. Both Kevin and Carol had careers in the travel industry – she as a travel agent, and he as an airline pilot – and had traveled to over 48 countries, staying in fine resorts and having local adventures. No other vacation came close to the great experience they had chartering and cruising the Caribbean Islands. So in 1999, Mainsail Yacht Charters became a reality, the perfect combination of years of travel industry experience, love of the islands, and a strong entrepreneurial drive. From day one Mainsail has been focused on one goal – offering outstanding customer service to help people have the best private yacht charter experience possible. After years of hard work and satisfying customers. Kevin is also a member of CYBA (Charter Yacht Brokers Association) for over 20 years as well as serving on the Board for VIPCA (Virgin Island Professional Charter Association) which allows him to have an up-to-date pulse on the entire Yachting industry.

Mainsail knows how important your Caribbean yacht vacations are to you.

Caribbean Yacht Charter Vacations are those precious times when friends and family experience new things, wonderful memories are created, and events and adventures become stories that are passed on for generations! Today, Kevin and Carol have three lucky, happy children who have grown up alongside Mainsail, with the family chartering yachts as often as possible in the Caribbean (even when the kids were babes in arms!), and pursuing a love of cruising the islands. Mainsail wants to help create those island holiday memories and experiences for you, your family, and your friends.
