About the Privilege 510

Launched in 2020, this Marc Lombard and Franck Darnet Design creation represents Privilege Marine's continued evolution in luxury cruising catamarans. At just over 56 feet overall, the 510 strikes an impressive balance between performance and comfort, making it an excellent choice for serious bluewater cruising and extended liveaboard adventures. The twin-keel catamaran configuration offers exceptional stability and shallow-water access with its modest 5.15-foot draft, while the generous 26.18-foot beam provides remarkable interior volume and deck space. Privilege Marine's reputation for building robust, seaworthy multihulls shines through in the 510's GRP construction, designed to handle demanding offshore passages with confidence. The fractional sloop rig delivers respectable performance with nearly 1,518 square feet of sail area, supported by twin 55-horsepower engines for reliable auxiliary power. With a sail area to displacement ratio of 21.95, the boat offers a good compromise between sailing performance and the stability preferred by cruising sailors. Notable design characteristics include Privilege's signature emphasis on safety, comfort, and practical layout optimization. The 510 continues the builder's tradition of creating catamarans that excel in long-distance cruising scenarios where reliability and livability take precedence over pure speed.

Performance Ratios
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

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
3.15
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. 9.44 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. 27.85 pounds/inch
