The first in the Nonsuch line of boat designs, the concept of a cruising catboat was proposed by Toronto businessman and sailor Gordon Fisher. Ellis designed the boats and they were built by Hinterhoeller Yachts in St. Catharines, Ontario, Canada, between 1978 and 1989, with 1080 examples completed.
Design
The Nonsuch 30 is a small recreational keelboat, built predominantly of fiberglass, with wood trim. It has a cat rig, an unstayed mast with a wishbone boom, a plumb stem, a vertical transom, an internally-mounted spade-type rudder controlled by a wheel and a fixed fin keel. It displaces and carries of ballast. The boat was built with three different interior floor plans, the classic, ultra and nova. The boat has a draft of with the standard keel and with the shoal keel fitted. The boat is fitted with a Westerbekediesel engine of. The fuel tankholds and the fresh water tank has a capacity of. The design has a PHRF racing average handicap of 180 with a high of 192 and low of 156. It has a hull speed of.
In a review Michael McGoldrick wrote, "although the Nonsuch's single large sail means that its windward ability will not equal that of a sloop with headsail, its modern underwater profile allows it to point higher than many people would expect. The fin keel and spade rudder found on the Nonsuches also does away with the windward helm which is characteristic of the Cape Cod catboats. One of the great advantages of the Nonsuch boats is that they are very easy to sail short-handed, or even single-handed. ... Because of the nature of their hull design, the Nonsuches are very big boats. In terms interior volume, they are probably 20% to 30% larger than their length would indicate. At first glance, Nonsuches may seem a little expensive, but their prices are more competitive when compared to that of boats that are 20% to 30% larger." In a review Richard Sherwood described the design, "the Nonsuch is typical of this type of boat. Although recently popular, there is nothing really new about either the cat rig or the wishbone boom. The mast is unstayed. The wishbone eliminates the need for vangs or travelers, and it imparts a draft to the sail. The sail can be raised, lowered, sheeted, and reefed from the cockpit. The catboat hull has been modified. Maximum beam is farther aft, entry is finer, aft lines are flat, there is a spade rudder, and the fin keel is available with two depths."
