Founded in 1906, Bellport Bay Yacht Club maintains a clubhouse at the foot of Bellport Lane from which sailing activates are coordinated. The club sponsors sailboat races for club members on Monday and Thursday evenings throughout the sailing season as well as sailing related social activities. Sailing lessons for young persons and adults are sponsored by a related organization, Bellport Bay Sailing Foundation. Club membership and sailing lessons are open to all. Meetings of the membership are held at the clubhouse three times a year in June, July and August.

The yacht club also hosts the annual Labor Day weekend regatta, on behalf of Great South Bay Yacht Racing Association, which includes the "Queen of the Bay" race. The club also occasionally hosts major regional and national class regattas.
