The sea in that clip was mild by comparison to what I went through (twice) in the Atlantic aboard a destroyer (USS English) that ran into two hurricanes a couple of years apart.
We found ourselves in the 'eye' (guessing 10-12 miles across) of the second, an extremely eerie sight, relatively calm seas, and a giant whirling wall of clouds all around us, extending thousands of feet above. The captain steamed along keeping us in the middle for a bit, told everyone to take a look, because we had to turn to stay with the rest of the HK group.
That storm ripped the depth-charge racks off the fantail, tore the steam torpedo mount off the 02 deck, ripped off all lifeboats, and tore the 'breakwater' fairing off both sides of the ship - literally tore half-inch steel plate as if it were paper. We lost one screw, a radar antenna, and several smaller radio antenna. Many thought there was no way we could survive - but we did. We were five-six months in dry-dock afterward for repairs.

Yep, that video was no hurricane. Judging from the white caps just a strong gale.
I was on the EDGE of a typhoon in 69 on a C-3 freighter in the South China Sea in seas like that. All we could do is stay in place and keep the bow headed into the seas for over 12 hours. Kinda scary.
Everyone was mad at the captain for choosing to try to beat the storm by routing us in the most direct line to Yokohama.
We left Da Nang before the ship has been secured for sea and were trying to drop the booms into the cradles on a rolling deck outside of the harbor. Good thing the Bosun knew his stuff!
Hit some really rough seas later returning to CONUS on the Great Circle Route in the North Pacific too. The third mate made us stand bow watch on the flying bridge. Bout froze my azz off.
What a long strange trip that was.
Ah memories, memories!
