Northern 1/4 Ton
Description
The Northern 1/4 Ton is a classic Canadian one-design racer designed by George Cuthbertson and George Cassian (Cuthbertson & Cassian) in 1972 specifically for the International Offshore Rule (IOR) Quarter Ton Cup, a popular handicap racing class emphasizing speed and agility in offshore and inshore events. Built in fiberglass by Northern Yachts (Port Credit, Ontario), this compact masthead sloop features a sleek fin keel hull with a transom-hung rudder for responsive handling, a narrow beam for planing potential, and a simple interior suited for 2–4 crew during day races or short overnights, with V-berths forward, settee berths, and minimal galley/head accommodations. Nearly identical to the Mirage 24 (which shared the same mold), it was produced in limited numbers (estimated <50 hulls) for competitive fleets, excelling in light to moderate winds with its efficient sailplan (SA/D 15.54) and trailerable design.
