Trimaran width can magnify carrier-deck motion

Would a trimaran aircraft carrier's flight deck create problems for pilots?

Yes; its extreme width can create large height differences across the deck in ocean waves, complicating landings.

A trimaran can be stable, but the great distance across its outer hulls creates a large differential when ocean waves set the platform moving. A flight deck spanning that width can present markedly different heights from one side to the other. That geometry matters during an aircraft's final approach, when the landing surface must remain predictable. The concept offers abundant deck area, but its seakeeping problem is operational rather than merely structural.
