Recently, ski guide Kent McBride experienced this first hand when he was returning from an expedition to the Antarctic in which he, and some teammates, skied a variety of locations in the region. After finishing up that excursion, the team was on its way back to Chile, when they caught out in the Drake Passage when things began to get a bit dicey. You can see the results in the video below, which show the waters there rolling dramatically, while we're informed that the wind gusts are topping out the Beaufort Scale, which is a ranking between 1 and 12 that indicates the force and danger of the winds. In this case, the ship was experiencing a 12 on that scale, which is hurricane force.
You can read more about Kent's adventures over at the Born Out There Blog, which is the official blog of First Ascent gear.
Warning: If you're prone to sea sickness, this video may be enough to put you over the edge.
