The Boat

The Sonar Paralympic Class - Three-person keelboat - Open

This keelboat’s configuration allows disabled sailors to sail efficiently and safely and enjoy a high level of performance and excitement. The racer has a well contoured sit-in cockpit and when the wind gets up and sailors are sitting on the side deck, there is no tendency to fall forward into the boat unless she takes a real knock-down, which is a rare event in a Sonar.

Sailors face into the boat and whether up on the deck or sitting down on the seats, the sailor’s backside is always higher than their feet. A crew of three must not exceed 14 classification points. The Sonar has been sailed in the Paralympics since sailing was included as a Paralympic sport in 2000.
