About the Pembroke 26 Westerly

Built by the respected British yard Westerly Marine from 1976 to 1979, this compact cruiser represents the design expertise of Laurent Giles, known for creating seaworthy vessels with traditional sailing characteristics. With only 97 examples produced during its brief production run, the Pembroke 26 has become a relatively rare find in today's used boat market. At 26 feet overall with a waterline length of 21.33 feet, this masthead sloop strikes an appealing balance between manageable size and cruising capability. The fin keel and transom-hung rudder configuration provides responsive handling, while the substantial displacement of 6,578 pounds and generous ballast ratio contribute to stability and seakindly motion in varied conditions. The boat's comfort ratio of 26.59 suggests excellent motion comfort for coastal cruising and short offshore passages, making it well-suited for weekend getaways and extended coastal exploration. Its capsize screening value of 1.78 indicates good stability characteristics for a boat of this size. The fiberglass construction reflects Westerly's reputation for solid, durable builds that have proven their longevity over decades. With 210 square feet of sail area driving a hull capable of 6.19 knots, the Pembroke 26 offers relaxed sailing performance ideal for those prioritizing comfort and safety over speed.

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
 9.6
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
 37.7
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
 302.6
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
 26.59
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
 1.78
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. 6.19 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. 634.10 pounds/inch
