Notes:

Gained attention after winning Royal Yachting Associations One-of a Kind Regatta of 1959?. (sailed by the designer and John Fisk). Solid bridgedeck? as with the Shark 20.

Probably one of the first cats from Sailcraft.

Dimensions are only our own estimates.

Reportedly some were built by Loflands in the USA.

An historically significant item and more information is sought.
