Lagoon 450 catamaran powers through choppy blue seas
What this video covers
The Lagoon 450 catamaran experienced reports of structural deformation in the forward bulkhead, a critical component that ties the two hulls together and resists torsional loads.▶ 0:58 Starting around 2020, owners identified cracks and visible distortion in this area, sparking widespread concern regarding the vessel's structural integrity.▶ 1:24 According to data reported by *Yachting Monthly*, approximately 155 boats were inspected by 2021 out of a fleet exceeding 1,000 units.▶ 1:56 Lagoon, in collaboration with naval architects at VPLP, attributed the deformation to a combination of factors, including heavy charter use, improper haulouts, groundings, and inconsistent construction methodology.▶ 3:23 The manufacturer implemented a formal program to provide inspections, engineering guidance, and structural reinforcement kits for affected vessels.▶ 4:57 While the company maintains that deformation in the side sections of the bulkhead does not pose an immediate dismasting risk, prospective buyers should verify the structural history of any Lagoon 450, specifically seeking documentation of official inspection and certified repairs.
