About the Lysander

With limited specifications available, the Lysander represents one of the more elusive sailboat designs in boating records. This scarcity of detailed information suggests either a limited production run or a boat that didn't achieve widespread market penetration during its era. Despite the sparse documentation, the Lysander name itself evokes classical maritime tradition, drawing from the ancient Spartan naval commander. This naming convention often indicates a designer's intention to create a vessel with strong seaworthy characteristics and reliable performance. Based on typical design patterns from boats of similar documentation levels, the Lysander likely targeted the recreational sailing market, probably suited for coastal cruising and day sailing applications. The limited availability of comprehensive specifications may actually appeal to certain buyers who appreciate discovering a lesser-known design with potential hidden qualities. For prospective owners researching this boat, the lack of detailed specs means any purchase would require particularly thorough inspection and sea trials. The Lysander could represent either an overlooked gem or simply a boat that didn't distinguish itself sufficiently in a competitive market, making hands-on evaluation essential for determining its true sailing characteristics and condition.

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
23.07
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
6.03
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
2.81
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. 5.46
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. 385.54
