About the Navy 44 Mk Ii

David Pedrick's Navy 44 Mk II represents a thoughtful evolution in modern cruising yacht design, combining performance-oriented sailing characteristics with comfortable accommodations for extended voyaging. Built by Pearson Composites starting in 2007, this masthead sloop demonstrates the designer's expertise in creating vessels that excel in both coastal and offshore environments. The yacht's fin keel and spade rudder configuration, paired with a substantial sail area of 1,020 square feet, delivers responsive handling and impressive sailing performance. With a displacement of 30,400 pounds and ballast ratio that provides excellent stability, the Mk II offers the confidence-inspiring sea-keeping abilities essential for serious cruising. The boat's moderate comfort ratio of 41.17 strikes an ideal balance between motion comfort and sailing efficiency. At 44.50 feet overall with a waterline length of 36.75 feet, the Navy 44 Mk II provides generous interior volume while maintaining manageable size for a cruising couple or small crew. The GRP construction ensures durability and relatively low maintenance, while the 50-horsepower engine provides reliable auxiliary power. This yacht appeals to sailors seeking a capable blue-water cruiser that doesn't sacrifice sailing performance for comfort, making it equally suited for weekend coastal adventures or extended offshore passages.

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
 16.82
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
 32.57
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
 273.43
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
 41.17
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
 1.62
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. 8.12 kn
S# (Speed Number) The Speed Number (S#) is a quick performance index. Higher values indicate a faster, more powerful design relative to its size.
Under 3.0 — Slow cruiser3.0–5.0 — Average cruiser5.0–7.0 — Performance cruiserOver 7.0 — Racer
 1.91
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. 1,654.53 pounds/inch
SA/Displacement (Calc) Calculated Sail Area to Displacement ratio using actual measured sail dimensions rather than reported values. More precise than the reported SA/Disp figure. 16.38
