About the Pegasus 700

Designed by Gordon V. Harris and built by Rydgeway Marine Ltd. in the UK starting in 1980, this 23-foot masthead sloop represents a thoughtful approach to compact cruising sailboat design. The Pegasus 700's proportions reveal a boat engineered for coastal cruising and weekend adventures, with her fin keel configuration providing good upwind performance while maintaining manageable handling characteristics for smaller crews. With a displacement of 2,866 pounds and ballast of 1,323 pounds, she carries nearly half her weight in ballast, contributing to stability and seaworthiness that belies her modest size. The comfort ratio of 13.31 suggests a relatively light displacement design that prioritizes sailing performance over pure comfort, while the capsize screening formula of 2.33 indicates reasonable stability for coastal and protected water sailing. Her fiberglass construction and masthead sloop rig offer durability and straightforward sail handling. The 18.58-foot waterline length generates a theoretical hull speed of 5.78 knots, making her a pleasant performer in light to moderate conditions. This combination of characteristics makes the Pegasus 700 well-suited for sailors seeking an affordable entry into cruising sailing, day sailing, or as a stepping stone to larger boats.

Performance Ratios
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
 46.16
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
 199.48
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
 13.31
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
 2.33
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. 5.78 kn
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. 547.70 pounds/inch
