About the South Coast 25

Designed by Warren Metcalf and built by South Coast Seacraft Co. beginning in 1969, this 25-footer represents solid coastal cruising capabilities in a compact package. With a moderate displacement of 4,200 pounds and substantial ballast ratio, the South Coast 25 offers reassuring stability for weekend cruising and day sailing adventures. The fin keel and spade rudder configuration provides responsive handling characteristics, while the masthead sloop rig delivers straightforward sail handling that appeals to both novice and experienced sailors. Her beam of 7.50 feet creates reasonable interior volume for overnight accommodations, though this boat truly shines as a coastal day sailer and short-term cruiser. The boat's comfort ratio of 20.28 suggests a relatively quick motion in seaways, making her better suited for protected waters and coastal sailing rather than extended offshore passages. Her capsize screening formula of 1.86 indicates good stability characteristics for coastal conditions. With only 100 hulls produced during her production run, the South Coast 25 remains a relatively uncommon find on the used boat market. This fiberglass construction offers durability and low maintenance, while her moderate sail area provides manageable power for single-handed sailing or small crew operations in typical coastal conditions.

Performance Ratios
PHRF Rating PHRF (Performance Handicap Racing Fleet) is a national racing handicap measured in seconds per nautical mile. Lower values indicate faster boats. Ratings are sourced from US Sailing's national database (median across 60+ regional fleets).
Under 0 — Ultralight racer0–90 — Performance racer90–150 — Cruiser/racer150–210 — Typical cruiserOver 210 — Heavy/slow cruiser
258
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
18.43
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
42.86
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
217.64
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
20.28
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
1.86
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. 6.07 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
2.66
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. 549.37 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. 18.44
