Boating and Sailing

Lake Ontario provides thrilling boating experiences for speed boats and sailing boats and windsurfing. In the early to mid 1970's, Association Island was the training facility for the US Sailing Team and was the center of numerous national and international sailing and windsurfing competitions, particularly leading up to the 1976 Montreal Olympics. As one of the Great Lakes, be prepared for fast-changing wind and wave conditions. Less experienced boaters should stay in the calmer Henderson Bay side of Association Island. Association Island does not yet rent out any motor boats or sailboats. Several of the local marinas rent out boats, but availability is limited so you should make plans well in advance. Also, there are several local licensed captains who will provide boat tours of Henderson Bay by the hour or half-day.
