About the 110

Designed by renowned naval architect C. Raymond Hunt in 1938, this compact 24-footer represents a significant piece of American sailing history. Cape Cod Shipbuilding produced 750 of these boats, establishing the 110 as a beloved coastal cruiser and trainer that has influenced generations of sailors. Hunt's design philosophy shines through in the 110's balanced proportions and seaworthy characteristics. The fin keel with bulb configuration and spade rudder arrangement provide responsive handling while maintaining stability, making this boat particularly well-suited for coastal cruising and sailing instruction. With a fractional sloop rig carrying 157 square feet of sail, the 110 offers manageable sail handling for small crews while delivering respectable performance. The boat's narrow 4.17-foot beam and moderate displacement create an efficient hull that moves well in light to moderate conditions. Originally constructed in plywood and later offered in fiberglass, the 110 demonstrates excellent build quality typical of Cape Cod Shipbuilding's craftsmanship. Its low comfort ratio of 10.58 and favorable capsize screening number of 1.72 indicate a boat designed more for day sailing and short coastal hops rather than extended cruising, though its seaworthiness has proven reliable in capable hands for decades.

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
26.8
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
32.97
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
69.66
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
10.58
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
1.72
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. 5.69 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. 268.20 pounds/inch
