About the Lagoon 47

Launched in 1992, this groundbreaking catamaran from renowned French designers Van Peteghem & Lauriot Prévost marked a significant milestone in production multihull sailing. The Lagoon 47 introduced many sailors to the advantages of twin-hull cruising, offering exceptional stability and interior volume that would influence catamaran design for decades to come. Built with fiberglass construction by Lagoon/Jeanneau, this 46-foot catamaran features twin keels and a fractional sloop rig with rotating spar technology that enhances sailing efficiency. The generous 24.92-foot beam provides remarkable deck space and allows for spacious accommodations below, while the shallow 3.58-foot draft opens up anchorages impossible for deeper monohulls. Perfectly suited for coastal and offshore cruising, the Lagoon 47 excels in charter fleets and long-distance voyaging. Its twin 40-horsepower engines (80 total) provide reliable auxiliary power and excellent maneuverability in tight quarters. The catamaran's design prioritizes comfort and practicality over racing performance, making it ideal for extended cruising with family or friends. This model established Lagoon's reputation as a leader in production catamarans, combining French design sophistication with practical cruising capabilities that appeal to sailors seeking space, stability, and comfortable passages.

Under 20 — Uncomfortably rough20–30 — Acceptable coastal30–40 — Good offshore comfortOver 40 — Very comfortable offshore
9.6
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
3.69
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. 8.75 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. 22.79 pounds/inch
