12 / 51 - score 58%
The Rk 21 is a 21.0ft masthead sloop designed by Peter Barrett and built in fiberglass by Coastal Recreation Inc. since 1972.
The Rk 21 is a light sailboat which is a high performer. It is stable / stiff and has a low righting capability if capsized. It is best suited as a racing boat.
This boat has an average score but ranks in the top quarter. It seems difficult to do much better. It is one of the best possible tradeoff for this request.
