There's something incredibly hypnotic about this Danish Iver Huitfeldt-class frigate bounding through some moderate waves. Up, and down. Up, and down. Splashy splash splash.
"Splashy splash splash" is, I believe, the technical term for what is happening here.
Though they are classified as frigates, the Iver Huitfeld-class ships are 455 feet long and displaces over 6,000 tons each, making them nearly as big as destroyers. And it definitely looks like they can take everything the North Sea throws at them, which is useful, because they're from Denmark.
