Way back around 1967 I was on an Army 1466 class LCU off the coast of Viet Nam in a typhoon. Green water over the conn. I watched a navy tin can off to our starboard, it was pitching wildly, taking green water over the bridge. Just as we used our light and asked if they needed assistance their light was asking us the same thing.
Well, since we're telling sea stories...
In the early 80's I was aboard the USS Tarawa, again transiting the edge of a Typhoon.
Her flight deck was 90ft above the water line, with the signal bridge 150ft above water line.
From the signal bridge I saw wave after wave put Blue Water over the flight deck and white water inundating the signal bridge.
She only had 28ft of draft with a flat bottom.
Once we cleared the storm we had to medevac nearly 60 Marines due to life threatening sea sickness.
Raw sewage and puke was sloshing around throughout the hanger bay and the mess decks.
