I learned how to walk on a boat. I’ve cruised, raced and lived aboard in my youth. I too share your dream of perfect afternoon sails and secluded anchorages. I started as a yacht broker in 2000 and have had the opportunity to work with clients in the purchase and sale of almost every type of cruising catamaran on the water today. I have helped hundreds of clients purchase yachts new and used from 30’-77’ and have come across every type of situation and problem that may arise in a transaction.
