That video should make you think about learning
how to heave to or run off.The big fish
boats or military boats can bash into this stuff but us sailors cant. It made me think of a passage
I made from Antigua
in a 44 foot cutter
. In 25 to 30 knots dead down wind
I passed an 8oo or 9oo foot tanker that was bashing to windward. The tanker was taking green water
a third of the way down its decks while we were dry and comfortable .That video was truly nasty conditions, but what direction you are going has a great effect on your conditions.____Grant.
