A landlocked basin protected by two breakwaters, Oak Bluffs Harbor is a popular stop with fisherman, recreational boaters, and families who are looking to be in the heart of the summer action. The harbor has the largest marina on Martha's Vineyard with well protected mooring field of around 80 slips, 50 moorings, fuel and pump-out facilities. Boarded by waterfront shops, restaurants and bars on the dock side, you’ll also find here fishing charters, water sports companies and a ferry dock for boats from Falmouth and Hyannis. Swimming is prohibited in the Harbor for safety reasons.

  Summer events include OB Harbor Festival in June.
