Pleasure Craft Guide
Over 2,000 pleasure crafts transit the Seaway locks each year. Pleasure crafts must be motor powered, at least 20 feet (6 meters) in length and at least 900 kg (1 ton) in weight. The Seaway entities provide either pleasure craft docks or tie-up areas, lock chamber tie-up assistance and VHF/telephone communications at the lock facility.
Further details are provided in the St. Lawrence Seaway Pleasure Craft Guide.
