Sonars are a triple handed keelboat raced by both adaptive and able bodied sailors. The Sonar is used by sailors who enjoy a team mentality, who are often interested in racing in addition to cruising. The Sonar has a mileu of possible adaptions. Several are described below.

Stability bars and transfer benches are also used in tandem in the Sonar to help crew and skipper move from side to side as the boat sails. An overview of stability bars can be found by clicking here.
Information on two different types of adaptive Sonar seats:
The gimbaled seat sits lower in the boat and swivels to keep the Skipper upright as the boat heels.
The video below shows both a transfer bench and an swiveling adapted Sonar seat (although the sound quality is poor)
Other possible adaptions include changing the main sheet purchase and the location of the mainsheet block. Purchase adjustments are covered on page 50 of US Sailing's Adaptive Sailing Resource manual, found here.
