About the Dc 14

Designed by the respected naval architecture firm Maclear & Harris and first launched in 1961, this compact catamaran represents an early entry into the small multihull market. Built by Duncan Sutphen Inc., the DC 14 features a distinctive twin daggerboard configuration that provides excellent shallow water capability while maintaining good upwind performance. The boat's lateen rig and 100 square feet of sail area deliver spirited performance for its 350-pound displacement, making it particularly well-suited for daysailing, club racing, and sailing instruction. The high sail area-to-displacement ratio of 32.25 indicates this is a lively performer that will accelerate quickly in light air and provide exciting sailing for experienced crews. Construction combines a fiberglass hull with a plywood bridgedeck, reflecting the building techniques of the early 1960s while keeping weight down. At just over 14 feet in length with a 6.67-foot beam, the DC 14 is easily trailerable and manageable for small boat sailors seeking the stability and speed advantages of a catamaran design. This boat appeals most to sailors interested in classic multihull sailing characteristics, weekend recreational sailing, and those who appreciate the unique handling qualities that twin hulls and daggerboards provide in protected waters.

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
32.25
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
89.23
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
3.38
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
3.79
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. 4.65 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. 1.72 pounds/inch
