About the F 24 Mkii

Ian Farrier's F 24 MkII represents a sophisticated evolution in folding trimaran design, bringing high-performance multihull sailing within reach of trailer-sailing enthusiasts. Built by Corsair Marine from 1994 onward, this 24-footer showcases Farrier's renowned expertise in creating fast, seaworthy trimarans that can be easily transported and launched. The boat's impressive beam of nearly 18 feet provides exceptional stability and generous deck space when deployed, while the innovative folding system allows the outer hulls to fold alongside the main hull for trailering and storage. Construction utilizes fiberglass with foam sandwich cores, delivering a strong yet lightweight structure that contributes to the boat's spirited performance. With a fractional sloop rig featuring a rotating mast and a substantial sail area-to-displacement ratio of 39.55, the F 24 MkII offers exhilarating sailing performance that can easily outpace conventional monohulls. The boat excels in coastal cruising and day sailing, where its speed and stability shine. While capable of longer passages in experienced hands, it's particularly well-suited for adventurous sailors who want multihull performance without marina slip limitations. The relatively shallow draft enhances its appeal for exploring shallow bays and launching from beaches, making it an excellent choice for sailors seeking versatility and performance.

Performance Ratios
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
2.49
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
5.9
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. 6.51 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
7.49
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. 9.05 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. 31.1
