About the Seafarer 29 Cb

Designed by the respected firm of McCurdy & Rhodes and first launched in 1972, this versatile coastal cruiser represents solid value in the sub-30-foot market. The Seafarer 29 Cb combines traditional full-keel characteristics with the shallow-water versatility of a centerboard configuration, making it equally at home in protected bays or venturing offshore for extended passages. Built by Seafarer Yachts using fiberglass construction, this masthead sloop delivers respectable performance with its moderate displacement of 6,665 pounds and well-proportioned sail plan of 356 square feet. The centerboard/keel hybrid design offers the best of both worlds: good tracking and seaworthiness from the fixed keel portion, plus the ability to explore thin waters with the board up. With a comfort ratio of 23.49, the boat provides a relatively stiff, comfortable ride in moderate conditions, while the capsize screening formula of 1.92 indicates good stability for coastal and near-offshore sailing. The generous beam of 9 feet creates a spacious interior for weekend cruising or short-term liveaboard situations. This design appeals to sailors seeking a capable, forgiving boat for learning offshore skills while maintaining gunkholing versatility.

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
 16.13
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
 37.36
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
 310.08
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
 23.49
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
 1.92
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. 6.18 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
 1.61
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. 683.36 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. 16.16
