About the Typhoon 25 Warner

Designed by Winthrop Warner in 1938 and built by Whitaker Marine, this classic wooden sailboat represents pre-war American yacht design at its finest. The cutter rig configuration provides versatility in sail handling, making it particularly well-suited for coastal cruising and weekend adventures. With a displacement of 11,500 pounds and 3,500 pounds of ballast in a traditional long keel configuration, this boat offers exceptional stability and seakindly motion in rough conditions. The substantial build and deep draft of 4.83 feet make it capable of offshore passages, though its 24.50-foot length keeps it manageable for smaller crews. The impressive comfort ratio of 44.11 indicates this design prioritizes motion comfort over pure speed, while the low capsize screening value of 1.6 speaks to its inherent seaworthiness. The wooden construction reflects the craftsmanship standards of its era, requiring dedicated maintenance but rewarding owners with classic aesthetics and solid performance. Hull speed reaches 6.04 knots, respectable for a boat of this vintage and type. This Warner design appeals to sailors seeking traditional character, proven seaworthiness, and the satisfaction of maintaining a piece of maritime history while enjoying reliable coastal and offshore sailing 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
9.45
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
30.43
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
611
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
44.11
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
1.6
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. 6.04 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. 653.77 pounds/inch
