About the Gozzard 31

Ted Gozzard's reputation for building seaworthy cruising sailboats shines through in this well-regarded 31-footer, which has earned respect among serious cruising sailors since production began in 1990. Built by North Castle Marine in Canada, this cutter-rigged vessel embodies traditional design principles with modern construction techniques. The Gozzard 31's long keel configuration and substantial 4,800-pound ballast provide excellent tracking ability and seakeeping characteristics that make it well-suited for offshore passages and extended cruising. With a displacement of 12,000 pounds and a comfort ratio of 26.19, this boat prioritizes stability and motion comfort over pure speed, making it an ideal choice for couples planning serious bluewater adventures. The cutter rig offers versatility in varying wind conditions, while the fiberglass construction ensures durability with reasonable maintenance requirements. At 36.17 feet overall with an 11-foot beam, the design provides comfortable accommodations without sacrificing the seaworthiness that Gozzard boats are known for. With a capsize screening formula of 1.93 and hull speed potential of 6.83 knots, this vessel strikes an appealing balance for cruisers who value safety and comfort over racing performance, making it a solid choice for serious coastal and offshore cruising endeavors.

Performance Ratios
SA/Displacement Sail Area to Displacement ratio measures how much sail power a boat has relative to its weight. Higher values mean more performance and speed.
Under 14 — Heavy cruiser, slow14–18 — Cruising sailboat18–22 — Cruiser/racerOver 22 — Performance racer
18.59
Ballast/Displacement Ballast to Displacement ratio shows what percentage of the boat's total weight is ballast. Higher values generally mean better initial stability and stiffer sail carrying.
30–35% — Typical cruiser35–45% — Stiff performance boatOver 45% — Racing oriented
40
Displacement/Length Displacement to Length ratio measures how heavy a boat is relative to its waterline length. Lower values mean a lighter, faster boat.
Under 100 — Ultralight racer100–200 — Light cruiser/racer200–300 — Moderate cruiser300–400 — Heavy cruiserOver 400 — Very heavy
304.8
Comfort Ratio Ted Brewer's Comfort Ratio predicts how comfortable a boat will feel in offshore conditions. Higher values mean a steadier, more comfortable motion in a seaway.
Under 20 — Uncomfortably rough20–30 — Acceptable coastal30–40 — Good offshore comfortOver 40 — Very comfortable offshore
26.19
Capsize Screening Formula The USHS Capsize Screening Formula estimates offshore capsize risk. Lower is safer — values under 2.0 are considered acceptable for offshore sailing.
Under 2.0 — Safe for offshore2.0–2.2 — Borderline offshoreOver 2.2 — Coastal use recommended
1.93
Hull Speed Hull Speed is the theoretical maximum speed of a displacement hull, calculated from waterline length. Most cruising sailboats reach this speed in moderate conditions. 6.83 kn
Pounds/Inch Immersion Pounds per Inch Immersion (PPI) tells you how much weight is needed to sink the boat one inch. Useful for calculating how additional gear and stores affect waterline. 1,021.91 pounds/inch
