About the Ph 41

Designed by the acclaimed team of Bob Perry and Huntingford, this Canadian-built cruiser emerged from Philbrook's Shipyard in 1975 as a well-balanced offshore sailing yacht. The Ph 41 represents classic 1970s design philosophy, combining seaworthiness with comfortable cruising accommodations in a 41-foot package. Built with fiberglass construction and featuring a fin keel with rudder on skeg configuration, the Ph 41 offers excellent directional stability and predictable handling characteristics. The masthead sloop rig provides versatile sail handling options, while the substantial displacement of 16,500 pounds and generous ballast ratio ensure good stability in challenging conditions. With a comfort ratio of 27.22, this yacht leans toward the cruising end of the spectrum rather than racing performance. The boat's moderate sail area to displacement ratio of 23.79 suggests steady, reliable progress rather than lightweight performance, making it well-suited for coastal cruising and longer offshore passages. Bob Perry's influence is evident in the yacht's seakindly hull form and practical deck layout. The Ph 41 appeals to sailors seeking a traditional, well-found cruising yacht with proven ocean-going capabilities and the confidence that comes from time-tested design principles.

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
23.79
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
46.48
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
239.53
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
27.22
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
1.89
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. 7.50 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. 1,343.35 pounds/inch
