About the Coronado 25 Cb

Built from 1966 to 1975, this compact cruiser represents solid American fiberglass construction from the early days of production sailboats. Designed by the team of Ed Edgar and Frank Butler for Coronado Yachts, the masthead sloop configuration provides straightforward sailing characteristics that have made it a popular choice for coastal cruising and day sailing. The boat's moderate displacement of 4,300 pounds and substantial ballast ratio create stable sailing manners, while the keel/centerboard configuration offers versatility that pure keel boats cannot match. This hybrid design allows access to shallow anchorages and launching ramps while maintaining reasonable windward performance. The centerboard setup makes trailer sailing practical, expanding cruising possibilities beyond a single home port. With a comfort ratio of 19.33, this design leans toward the sportier end of the cruising spectrum rather than heavy-displacement passage making. The capsize screening formula of 1.97 indicates good stability characteristics suitable for coastal waters. The 273 square feet of sail area provides adequate power for the boat's size, making it responsive in light to moderate conditions. For sailors seeking an affordable entry into cruising or a manageable boat for coastal exploration, this Coronado offers proven seaworthiness with the practical advantages of shallow-draft capability.

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
16.56
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
41.86
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
238.16
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
19.33
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
1.97
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. 6.00 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
2.45
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. 573.13 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. 18.62
