I have been onboard a couple of vessels in sea’s like
this and I always wondered why the welds that held the
steel plates together didn’t pop when she would drop
into a forty foot trough over and over again.
you don’t get a lot of sleep waiting to get through one
of these monsters.
Probably don't keep much food down, either.
My fear was not the welds, but the possibly of the darn thing turning over. I remember on one ship rated at 38 degrees before turning over, we hit a storm that put us at 42 degrees ... constipation was not a worry.
Try being aboard a fishing boat, in 30’ swells. can you say, experience six motions all at once ....rock, roll, pitch, yaw, surge, sway and heave! Terrifying. :)
