Why 90% of Catamarans Will Never Cross an Ocean - They Fail this ONE Ocean Test

Catamarans cross the Atlantic every single winter — so why do naval architects, marine surveyors, and the insurance industry quietly agree that most of them were never actually built to survive an ocean? In this video we break down the real engineering gap between a charter-optimized cruising cat and a genuine bluewater boat: the bridge deck clearance test almost no buyer checks, why published displacement figures are routinely wrong, the Lagoon 450 structural bulkhead scandal, four recent real-world catamaran failures on ocean passages, why a capsized catamaran can never right itself again, and the one line buried in the CE "Category A – Ocean" certification that quietly excludes the exact conditions that sink boats. We also look at what the other 10% — genuine offshore designs like Outremer, Balance, and HH — actually get right.
