In the Gulf stream it's the wave period as well as wave height that causes damage.

This from a buoy of the Ga coast this evening

Dominant Wave Period (DPD): 10 sec
Average Period (APD): 5.0 sec

If wave height was 6 meters, that's a roller coaster that can quite possibly rip out mast stays.

People make it a habit not to go outside when there's a north wind blowing against the Gulf Stream. It's all about waiting for the weather window.
