What the fleet has seen

The Lagoon 51, as the fleet has seen it

The Lagoon 51 is a 15.3-meter fractional sloop catamaran, designed by VPLP Design and built by Lagoon since 2022, featuring an exterior by Patrick le Quement and interior by Nauta Design. Its mast is moved forward compared to the Lagoon 50, resulting in a longer boom, a shorter mast, and a lower center of effort, replacing the self-tacking jib with a traditional genoa track system. The flybridge, accessible from both port and starboard, centers the helm for improved visibility and includes a large seating area. Aboard Igor Stropnik's Lagoon 51, a four-person crew departed the Canary Islands for Saint Lucia as part of the 2024 Atlantic Rally for Cruisers (ARC), carrying a mainsail, genoa, code zero, and a large parasail spinnaker.1:47 Downwind, a third-reefed main with a preventer and a large headsail reduced rudder load and kept the boat tracking straight.1:28:11 During the crossing, halyard chafe at the mast sheave emerged as a problem, a design issue seen across multiple catamaran brands.1:51:16 The Lagoon 51 features two kilowatts of solar panels and a large lithium battery bank.23:34 Its aft platform extends to create a spacious swimming terrace when the dinghy is deployed.1:04:15 The interior includes a redesigned saloon that eliminates the central mast support, providing more open space and an additional seating area.15:14 The boat's hydraulic steering contrasts with the cable steering on smaller Lagoon models.7:45
