About the Cal 2 25

Designed by the renowned C. William Lapworth, this compact 25-footer represents classic California sailing heritage from the late 1970s and early 1980s. Built by Bangor Punta Marine between 1977 and 1983, the Cal 2 25 found favor among sailors seeking an affordable yet capable coastal cruiser, with 392 hulls launched during its six-year production run. The boat's fin keel and spade rudder configuration delivers responsive handling and decent windward performance, while the masthead sloop rig provides straightforward sail handling. With a displacement of 4,500 pounds and 2,000 pounds of ballast, she offers reasonable stability for coastal adventures and weekend cruising. The 22-foot waterline generates a hull speed of 6.29 knots, making her sprightly in light to moderate conditions. Lapworth's design emphasizes sailing performance over interior volume, though the 9-foot beam provides adequate space for a small galley and V-berth accommodations. The relatively low comfort ratio of 16.21 suggests she's better suited for day sailing and short coastal hops rather than extended offshore passages. Her capsize screening value of 2.18 indicates good stability characteristics for protected waters and near-coastal sailing, making her an excellent choice for sailors developing their skills or seeking an economical entry into keelboat sailing.

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
 18.48
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
 44.44
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
 188.67
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
 16.21
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
 2.18
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
 3.03
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. 707.48 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. 18.51
