About the Abbott 27

Designed by Bill Abbott Sr. and built by Abbott Boats Inc. in Canada starting in 1986, this 27-footer represents a thoughtful approach to coastal cruising and club racing. The fiberglass construction with balsa core hull and deck creates a strong yet lightweight platform that delivers respectable performance while maintaining comfort for extended sailing. With its masthead sloop rig and fin keel configuration paired with a transom-hung rudder, the Abbott 27 offers responsive handling and good upwind performance. The moderate displacement of 6,000 pounds, supported by 2,700 pounds of ballast, strikes an appealing balance between stability and sailing ability. A capsize screening formula of 1.98 indicates solid seaworthiness for coastal waters, while the comfort ratio of 20.59 suggests this boat leans toward performance rather than heavy cruising accommodations. The sail area to displacement ratio of 17.3 positions this boat as a capable performer in moderate conditions, making it well-suited for day sailing, weekend coastal cruising, and club racing. Its Canadian heritage and robust construction have earned it recognition among sailors seeking a reliable, well-built boat that can handle both spirited sailing and comfortable cruising in protected and near-coastal waters.

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
 165
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
 17.3
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
 45
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
 227.49
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
 20.59
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
 1.98
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. 6.39 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
 2.43
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. 731.59 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. 17.26

I (Foretriangle Height) 34.25 ft / 10.44 m
