About the Princess 37 Robb

Designed by the renowned Arthur Robb in 1958, this classic 37-footer represents the golden age of traditional yacht design when seaworthiness and elegance went hand in hand. Built by Hong Kong's respected Cheoy Lee Shipyard, the Princess 37 showcases beautiful wood construction that has stood the test of time across more than six decades. The masthead yawl rig provides exceptional sailing versatility, allowing for balanced sail handling in varying conditions while the mizzen offers additional options for heavy weather sailing. Her long keel configuration delivers outstanding directional stability and self-steering capabilities that make her particularly well-suited for offshore cruising and passage making. With a displacement of 20,000 pounds and a comfort ratio of 51.97, this design prioritizes seakindly motion over pure speed, making extended voyages more pleasant for crew and passengers alike. The substantial build quality typical of Arthur Robb's designs, combined with her proven seaworthiness, has earned the Princess 37 a loyal following among serious cruising sailors who value traditional yacht virtues. Her moderate beam and elegant proportions reflect classic yacht aesthetics while providing adequate interior volume for comfortable cruising accommodations suitable for coastal and offshore adventures.

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
 13.67
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

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
 51.97
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
 1.4
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. 6.90 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. 899.53 pounds/inch
