About the Harpoon 62

Designed by C&C Design and built by Boston Whaler from 1979 to 1983, this compact 20-footer represents an interesting collaboration between a renowned yacht design firm and a builder famous for powerboats. With only 150 hulls produced during its four-year run, the Harpoon 62 remains a relatively uncommon sight on the water. The boat's fractional sloop rig and moderate sail area of 210 square feet make it well-suited for day sailing and weekend coastal cruising. Its fin keel configuration with transom-hung rudder provides responsive handling, while the 550-pound ballast ratio offers reasonable stability for a boat of this size. The hull speed of 5.33 knots reflects typical performance expectations for casual sailing rather than competitive racing. At 1,700 pounds displacement, this fiberglass boat strikes a balance between portability and seaworthiness. The comfort ratio of 9.58 suggests a relatively stiff ride in choppy conditions, typical of smaller, lighter vessels. With its 8-foot beam and moderate draft of 3.5 feet, the Harpoon 62 can access shallow waters while providing adequate interior volume for a compact cruiser. This boat appeals most to sailors seeking an affordable, manageable vessel for protected waters and near-coastal adventures.

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
 23.64
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
 32.35
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
 191.32
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
 9.58
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
 2.68
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. 5.33 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
 3.3
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. 452.50 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. 21.29
