Sonar


The Sonar is a 23.0ft fractional sloop designed by Bruce Kirby and built in fiberglass by Seidelmann Yachts since 1980.

860 units have been built.

The Sonar is a light sailboat which is a very high performer. It is very stable / stiff and has a low righting capability if capsized. It is best suited as a racing boat.
