About the Newport 41S

Designed by the renowned C&C Design Group and built by Capital Yachts starting in 1974, this masthead sloop represents solid 1970s sailing yacht engineering with a focus on performance cruising. The fin keel and spade rudder configuration delivers responsive handling characteristics that made these boats popular among sailors seeking both comfort and sailing ability. With a moderate displacement of 18,000 pounds and substantial ballast ratio, the Newport 41S offers reassuring stability for coastal and offshore passages. The boat's sail area of 750 square feet provides adequate power in light to moderate conditions, while the hull's 30-foot waterline length contributes to a respectable hull speed of 7.34 knots. The comfortable 33.26 comfort ratio suggests good motion at sea, making extended cruising more pleasant for the crew. The fiberglass construction and proven design have helped many of these boats maintain their seaworthiness over the decades. The moderate beam of 11.25 feet balances interior volume with sailing performance, while the 6.25-foot draft provides good upwind ability. Powered by a reliable 35-horsepower engine, these boats handle well under power in tight quarters or calm conditions, making them versatile choices for serious coastal cruisers and occasional offshore sailors.

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
17.54
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
45.64
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
297.62
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
33.26
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. 7.34 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
1.79
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. 1,205.92 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. 17.33
