About the Endeavour 54

Launched in 1990, this substantial cruising sailboat represents Endeavour Yacht Corporation's commitment to building comfortable, seaworthy vessels for serious cruisers. Designed by R.C. Lazzarra, the Endeavour 54 combines traditional styling with modern construction techniques, featuring a fiberglass hull with fin keel and rudder on skeg configuration that provides excellent directional stability and tracking. With its generous 15.75-foot beam and substantial 55,000-pound displacement, this masthead sloop prioritizes interior volume and stability over pure sailing performance. The impressive comfort ratio of 45.99 indicates exceptional motion comfort at sea, making it well-suited for extended offshore passages and live-aboard cruising. The moderate sail area of 1,018 square feet and conservative sail area-to-displacement ratio of 11.31 emphasize reliability and ease of handling over racing performance. The capsize screening formula of 1.66 falls within acceptable parameters for offshore sailing, while the hull's design delivers a theoretical hull speed of 8.87 knots. The fin keel's moderate 4.92-foot draft allows access to many harbors while maintaining good windward performance. Powered by a 75-horsepower engine, the Endeavour 54 offers dependable auxiliary propulsion for calm conditions and maneuvering in tight quarters.

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
11.31
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
23.64
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
291.61
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
45.99
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
1.66
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. 8.87 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. 2,466.60 pounds/inch
