There is a particular size of vessel which suffers far more than others in heavy seas. For those who have seen the first
Pirates of the Caribbean motion picture, the vessel shown there as
Interceptor is the type of vessel to which i refer. That is a brig (two-masted, square rigged, ship's hull). The one used in the motion picture is
Lady Washington, a reconstruction of a brig which was posted to the Pacific Northwest in the 1790s. She was the first American vessel to visit Japan, and foundered in Philippine waters in 1798.
Originally rigged as a sloop, she was "re-rigged" as a brig after reaching the Pacific, which simply made sense, given that her hull type was actually your basic broad beamed tub. With a length at the load water line of 58', and at 22' at the beam, she was less than three times as long as she was broad.
Vessels of such dimensions, and that particular length suffer in most heavy sea conditions in most oceans (except, perhaps, for the Southern Ocean, which is where
Nimitz was in the episode to which FM referred) because her size is just right for losing the wind in her mainsails as she dips into a troth, while the topsails and top gallant (if she has them rigged) continue to draw, and then while rising to top of the next wave, being obliged to fight the sudden exposure of the mainsails, which "wants" to turn her broadside so that she'll broach.
When
Lady Washington was sailed to St. Vincent for the motion picture, she was caught in a heavy gale in the Pacific between Long Beach and the Panama Canal, and suffered heavy damage to her spails, spars and rigging.
