About the Sakonnet One Design

Developed for the sheltered waters of Sakonnet Point in Rhode Island, the Sakonnet One Design is a classic New England daysailer with deep roots in regional sailing culture. Designed for competitive one-design racing within its local fleet, this boat reflects the tradition of purpose-built class racers that flourished along the northeastern coastline throughout the twentieth century. As a one-design class, the Sakonnet is built to strict specifications that ensure all competing boats are essentially identical, placing the outcome of races squarely in the hands of the sailor rather than the boat builder. This makes it an excellent platform for developing and sharpening racing skills in a fair and competitive environment. Its intended waters suggest a hull suited to the relatively protected bays and estuaries typical of coastal New England, making it well matched to inshore and daysailing conditions rather than offshore passages. For buyers interested in joining an established local fleet or exploring a piece of New England sailing heritage, the Sakonnet One Design offers a meaningful connection to a close-knit sailing community where tradition and seamanship remain at the forefront.

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
16.97
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
19.62
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
1.9
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. 5.09
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. 322.03
