About the Leopard 45

Built by Robertson and Caine from Simonis-Voogd's proven design, this popular catamaran has established itself as a standout choice for serious cruising sailors since entering production in 2016. With 368 hulls delivered through 2024, the Leopard 45 demonstrates the market's strong confidence in its blend of performance and livability. The fractional sloop rig with rotating spar delivers impressive sailing characteristics, while the twin-keel catamaran configuration provides the shallow 4.92-foot draft that opens up countless anchorages unavailable to deeper monohulls. At 24.17 feet of beam, the platform offers exceptional stability and interior volume without sacrificing seaworthiness for offshore passages. This fiberglass construction catamaran excels at both coastal cruising and extended blue-water voyaging. The design prioritizes the comfort and safety features that matter most to cruising couples and families, including excellent load-carrying capacity and multiple social areas both above and below deck. The generous sail area combined with moderate displacement creates a responsive sailing platform that doesn't require extreme weather to perform well. Twin 45-horsepower engines provide reliable auxiliary power and excellent maneuverability in tight quarters, making this an ideal vessel for exploring diverse cruising grounds from the Caribbean to the Mediterranean.

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
18.55
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
16.63
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
3.03
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. 8.78 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. 22.23 pounds/inch
