"The little sister of our Sanderling and Marshall 22, this popular size is perfect for youngsters or families wanting a solid, stable, daysailer. With similar seaworthy characteristics as the larger cats, she has proven to be ideal for worry free performance, dependability, and ease of handling. With an optional hinged mast and a trailer, she makes an ideal trailer-sailor that can be rigged, launched, and ready to sail in minutes. Nose up to a beach for a picnic and a swim then push off for a leisurely sail home."
