What kind of sailboat is a Sonar, and what are the features of this boat?
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.
The video below shows both a transfer bench and an swiveling adapted Sonar seat (although the sound quality is poor),
Other adaptions include Stability bars and drop in seats are also used in tandem in the Sonar to help crew and skipper move from side to side as the boat sails.
Sonars also have different seating options, including:
Mid-Boat Seat: This seat is installed towards the center of the Sonar and is designed to accomodate individuals using Sip and Puff systems. The seat can be positioned from side to side using cleats.
Gimbaled Mid-Boat Seat: The gimbaled seat sits lower in the boat and swivels to keep the Skipper upright as the boat heels.
