About the Newport 27 3

Designed by the renowned C&C Design Group and built by Capital Yachts starting in 1975, this 27-footer represents a thoughtful approach to compact cruising. The Newport 27 3 features a modern fin keel and spade rudder configuration that delivers responsive handling and good windward performance, making it well-suited for coastal cruising and weekend adventures. With a displacement of 6,000 pounds and a comfortable beam of 9.25 feet, this fiberglass sloop strikes a nice balance between stability and performance. The masthead sloop rig provides 366 square feet of working sail area, offering adequate power for most conditions while remaining manageable for smaller crews. The boat's SA/Displacement ratio of 17.79 suggests moderate performance characteristics that favor reliability over racing speed. The Newport 27 3's design emphasizes practical sailing qualities over extreme performance, making it an appealing choice for sailors seeking their first keelboat or those wanting a straightforward coastal cruiser. Its 5.16-foot draft allows access to many harbors and anchorages while providing enough depth for stability. The comfort ratio of 20.34 indicates this boat will have relatively quick motion in a seaway, typical of boats in this size range prioritizing sailing ability over pure comfort.

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
 17.79
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
 251.56
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
 20.34
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
 2.04
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. 6.29 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
 2.23
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. 727.13 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. 17.78
