The 2023 Lagoon Seventy 7 is a 77-foot fiberglass catamaran built for serious cruising and entertaining. Twin Nanni 230hp diesel engines drive Brunton folding propellers, paired with two Cummins generators and 180,000 BTUs of Dometic air conditioning. The yacht carries a comprehensive navigation suite: six Raymarine Axiom displays, 3D downvision and 3D sonar systems, Quantum Doppler radar, SEA AI collision avoidance, Evolution autopilot with a backup independent system, and dual aft-facing cameras. A hydraulic Tenderlift manages a 110hp Williams diesel tender.
The layout features five cabins and five heads, configured with four owner staterooms and a forward galley that opens the main saloon. The owner's master suite includes Lagoon's signature opening side door that extends into a private swim platform. Accommodation flows from the aft cockpit—a shaded lounge and dining area—through the light-filled interior, while a sunken forward lounge and custom foredeck shade tent provide additional outdoor living space. The flybridge offers daybeds, generous seating, and a full wet bar with three refrigerators and an icemaker.
The sail plan consists of Incidence ZZ Ultra cloth main, G1, and G3 sails, plus a 2.25 oz A2 and new C0 by Precision Sails. Facnor hydraulic furlers independently manage the Genoa, Jib, and Code Zero. The yacht was professionally crew-managed from delivery in France in 2023 and has been consistently well-maintained throughout her operation.
