About the Continental 25 Whitby

Designed by T. Sunden and built by Canada's Whitby Boat Works starting in 1961, this traditional masthead sloop represents classic sailboat design from the early 1960s. With only 35 hulls produced, the Continental 25 has become a relatively rare find among vintage sailboat enthusiasts seeking authentic character and time-tested seaworthiness. The boat's long keel configuration with transom-hung rudder delivers exceptional directional stability and predictable handling characteristics that new sailors appreciate. At 5,500 pounds displacement on a 25-foot hull, this fiberglass yacht carries substantial ballast for its size, contributing to impressive stability and comfort in varied conditions. The generous comfort ratio of 28.29 indicates a motion that favors relaxed cruising over aggressive performance sailing. Built for coastal cruising and weekend adventures, the Continental 25 excels in protected waters and moderate offshore conditions. Her conservative sail plan and substantial construction make her well-suited for sailors prioritizing safety and ease of handling over racing performance. The long keel tracks beautifully and forgives steering mistakes, while the masthead sloop rig keeps sail handling straightforward. For buyers seeking vintage charm with proven seaworthiness, the Continental 25 offers the appeal of traditional design principles in a manageable trailerable package.

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
 261
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
 14.83
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
 314.88
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
 28.29
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
 1.65
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. 5.97 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
 1.51
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. 513.70 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. 15.28
