About the Eastsail 25

Designed by Eliot Spalding and introduced in 1984, this compact cruiser represents a thoughtful approach to small boat offshore capability. The Eastsail 25's traditional long keel configuration and cutter rig arrangement reflect classic cruising priorities, emphasizing seaworthiness and self-sufficiency over pure performance. With a displacement of 7,200 pounds and 2,300 pounds of ballast, this fiberglass yacht carries substantial weight for her 25-foot length, contributing to her stability and sea-kindly motion. The long keel design provides excellent tracking ability and creates a protected aperture for the propeller and rudder, valuable features for cruisers venturing into challenging waters. The cutter rig offers exceptional versatility in varying wind conditions, allowing sailors to balance the sail plan effectively by using different combinations of headsails. This makes the boat particularly well-suited for coastal cruising and short-handed sailing, where the ability to reduce sail area forward while maintaining drive becomes crucial. Her comfort ratio of 29.13 indicates a motion that favors stability over quickness, while the capsize screening formula of 1.76 suggests reasonable offshore capability for experienced sailors. The 400 square feet of sail area provides adequate power for her displacement, though performance will be more about steady progress than exciting speed.

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
17.22
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
31.94
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
355.64
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
29.13
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
1.76
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. 6.12 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. 632.64 pounds/inch
