About the Friendship 25 Ts

Designed by renowned Dutch naval architect Koos De Ridder and built by Friendship Yachts starting in 1984, this compact fractional sloop represents thoughtful European engineering for coastal cruising and recreational sailing. The lifting keel configuration makes this 24.61-foot yacht particularly appealing for shallow water exploration and trailer sailing, allowing access to harbors and anchorages unavailable to fixed-keel boats. With a displacement of 2,866 pounds and 992 pounds of ballast, the boat strikes a reasonable balance between stability and performance. The 8.20-foot beam provides adequate interior volume for weekend cruising while maintaining good sailing characteristics. Her 248 square feet of sail area and SA/Displacement ratio of 19.72 indicate moderate performance potential, making her well-suited for relaxed coastal sailing rather than aggressive racing. The comfort ratio of 12.16 suggests a relatively quick motion in seaways, typical of smaller coastal cruisers, while the capsize screening formula of 2.31 indicates reasonable initial stability for protected waters sailing. Friendship Yachts built these boats with fiberglass construction, ensuring durability and low maintenance. The lifting keel feature, combined with her modest draft when raised, makes this an excellent choice for gunkholing, shallow bay sailing, and those seeking versatile coastal exploration capabilities.

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
 19.72
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
 34.61
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
 138.16
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
 12.16
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
 2.31
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. 6.14 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
 3.95
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. 615.29 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. 19.71
