What the fleet has seen

The Lagoon 51, as the fleet has seen it

The Lagoon 51 is a fractional sloop catamaran, designed by VPLP Design with exterior styling by Patrick le Quement and interior design by Nauta Design, built by Lagoon from 2022. It measures 15.3 meters LOA, with an 8.1-meter beam, 1.4-meter draft, and 19,914 kg displacement. Aboard Igor Stropnik, a Lagoon 51 was delivered from Bordeaux, France, to Croatia, covering approximately 2,700 nautical miles through the Gironde river, Bay of Biscay, Portugal, the Strait of Gibraltar, and the Mediterranean.0:39 The delivery crew navigated a swing bridge and lock system in Bordeaux, which opens four times weekly, and managed a 50-nautical-mile river transit to the Atlantic.1:41 The vessel consumed an average of five liters of fuel per hour at 2,000 RPM, achieving roughly one nautical mile per liter from its 1,000-liter tank.16:58 The crew used the GT Orca Atlantica app to track orca sightings and attacks between Portugal and Gibraltar, mitigating risk by hugging the coast at depths under 20 meters; the Lagoon 51's short, forward-mounted rudders and twin propellers were considered less attractive to orcas than a monohull's deep, free-hanging rudder.53:39 Downwind sailing favored a butterfly configuration over gybing to improve VMG and reduce hobby-horsing in following seas.1:22:11 The flybridge offered crew capacity, shade, and enhanced visibility for spotting marine hazards.5:30
