The Lagoon 51, as the fleet has seen it

The Lagoon 51 is a fractional sloop catamaran, designed by VPLP Design and built by Lagoon since 2022, with exterior design by Patrick le Quement and interior design by Nauta Design. It measures 15.3 meters LOA, has an 8.1-meter beam, a 1.4-meter draft, and displaces 19,914 kg. Aboard *Igor Stropnik*, a Lagoon 51 departed the Canary Islands for Saint Lucia as part of the Atlantic Rally for Cruisers (ARC) 2024, carrying a mainsail, genoa, code zero, and a large parasail spinnaker.watch The crew found that a third-reefed main with a preventer and a large headsail reduced rudder load downwind.2:04:46 During this passage, halyard chafe at the mast sheave emerged as a problem, a design issue seen across multiple catamaran brands.1:09:43 Another Lagoon 51 was delivered from Bordeaux, France, to Croatia, a 2,700-nautical-mile passage where the crew used the GT Orca Atlantica app to navigate the orca-attack zone, assessing the boat's short forward-mounted rudders and twin propellers as less attractive to orcas.54:31 The flybridge was noted for its crew capacity, shade, and visibility. *Lauren Landers Sailing* chartered a Lagoon 51 in the British Virgin Islands, where a loose mainsail halyard required a videographer from another vessel to climb the mast due to the charter boat's lack of a bosun's chair.2:19:50
