About the Cockler 25

Designed by renowned British naval architect Maurice Griffiths in 1958, this traditional wooden cutter represents classic coastal cruising at its finest. The Cockler 25 embodies Griffiths' philosophy of creating seaworthy small craft capable of handling challenging conditions with grace and reliability. Built with traditional wood construction, the design features a moderate displacement hull with generous beam that provides excellent stability and comfortable accommodations for weekend cruising. The deep draft and substantial ballast-to-displacement ratio create a stiff, well-balanced platform that tracks beautifully in varied sea conditions. Her cutter rig offers versatility in sail handling, particularly valuable when sailing short-handed or in demanding weather. The keel-centerboard configuration gives this boat remarkable versatility, allowing access to shallow anchorages while maintaining the directional stability of a deep keel when the board is lowered. This hybrid approach makes her equally at home exploring thin-water gunkholes or making offshore passages. With her moderate comfort ratio, the Cockler 25 strikes an ideal balance between performance and livability for coastal cruising adventures. Her conservative design reflects Griffiths' emphasis on seaworthiness over speed, making this an excellent choice for sailors prioritizing safety and traditional sailing character over racing performance.

Performance Ratios
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
32.26
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
311.93
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
31.53
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
1.64
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. 6.29 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. 628.87 pounds/inch
