The 2024 Lagoon 51 is a luxury catamaran built on a fiberglass hull powered by twin Yammer 4JH80 diesel engines of 80 horsepower each. This 51-foot catamaran, with a 26-foot 7-inch beam, combines spacious accommodations with capable offshore performance. The boat features a full electronics suite from Raymarine including dual displays, autopilot with gyro, radar, AIS, and VHF systems, along with comprehensive navigation and entertainment equipment at both helm and navigation stations.
The interior layout provides four cabins and three heads throughout the twin hulls. Accommodations include Alpi Sand Oak woodwork with dark oak flooring, a convertible double berth in the salon, and comfortable sleeping arrangements across the bow compartments. The galley is equipped with dual refrigeration units totaling 230 liters, a 100-liter freezer, and pre-fittings for microwave, dishwasher, and washer/dryer. Three gray water holding tanks handle waste management, while a 100-liter-per-hour watermaker provides independent freshwater generation.
Systems throughout the boat reflect modern cruising requirements. Climate control includes reverse-cycle air conditioning on 110-volt North American specification. Power generation combines an integrated solar array totaling 2,728 watts—spread across roof and bimini panels—with a generator and 2,000-watt inverter; additional lithium battery options supplement the standard AGM service batteries. A 24-volt electrical bow thruster with dedicated power supports maneuvering in tight quarters.
Sailing capability centers on a white aluminum rig with full-batten mainsail, genoa, and code 0 asymmetrical configuration, all equipped with electric furlers and Harken flatwinder winches. The aft cockpit features an 80-liter refrigerator, ice maker, and plancha grill; the flybridge spans much of the boat's length with integrated solar paneling, forward sunpads, and dual steering stations. Exterior equipment includes a dinghy hoist system with hydraulic platform, tender lift, folding gangway, and a 34-foot tender with 20-horsepower outboard included. The boat was launched and rigged new, then antifouled before commissioning.
