I did that in open ocean for 2 hours once. Every wave swamped the whole bow and often the wheelhouse of our 50 foot charter boat (I was deckhand).
I was sure I was going to die. The Coasties wouldn’t come out.
While we were about to die, the sun came up and spread gorgeous golden G-d rays through the dark purple scudding clouds.
Then groups of pilot whales started jumping from the tops of the 40 foot waves, frolicking for fun.
While we were going to die. For sure. I’m feeling sick again.
Amended: The waves were peaking around 40 feet, and our bow would climb one, the front half of the boat would go airborne, then plunge down into the trough, and plow THROUGH the next wave. So we only buried the bow every-other wave.
