About the Kelley 24

Designed by Bruce Kelley and first launched in 1978, this compact sloop represents a thoughtful approach to small boat cruising with its distinctive lifting keel configuration. Built by Intrepid Marine Services in fiberglass construction, the Kelley 24 offers versatility that appeals to sailors seeking shallow-water access without sacrificing sailing performance. The lifting keel system is the boat's standout feature, allowing draft adjustment from the full 5-foot depth for optimal sailing performance to a reduced draft for exploring shallow anchorages and launching from trailers. This flexibility makes it particularly well-suited for coastal cruising, lake sailing, and gunkholing adventures where traditional deep-keel boats cannot venture. With a displacement of 3,400 pounds and 268 square feet of sail area in a masthead sloop configuration, the design strikes a reasonable balance between stability and performance. The comfort ratio of 13.36 suggests a relatively stiff, quick motion that favors day sailing and weekend cruising over extended offshore passages. The capsize screening value of 2.45 indicates the boat falls within acceptable limits for coastal sailing in moderate conditions. Bruce Kelley's design philosophy emphasized practical sailing solutions, and this 24-footer delivers exactly that—a manageable, trailerable cruiser capable of exploring diverse sailing grounds while remaining easy to handle for small crews.

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
19.01
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
221.29
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
13.36
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
2.45
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. 5.84 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
2.67
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. 625.26 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. 19.02
