Growing up I always wanted to be a captain on a ship. Wear a white hat, have a great big gray beard, hold a pipe but never actually smoke it, all those fun things. After seeing what massive storm swells look like off the south coast of Ireland, I might want to rethink that.
The Reddit user that posted this video, stevgoldhound, says that he's a merchant mariner on a 203-foot boat, and that this is a bit of a typical storm. Previously he's encountered sees as high as 80 feet before.
In a storm like this, you've got two options. Keep all your future sailing to inner-city ponds, while you cower in terror at the sea and the incessant squeaking of the windshield wiper, or lash yourself to the bow, and screaming at the mighty ocean to hit you with all it's got.
I don't know why those are the only two options, but that is what they are and I don't make the rules.
Good luck out there, sailor.
