On the USCG Confidence winter time Gulf of Alaska , I recall two or three days where it seemed everyone on the crew was sea sick. I recall on watch puking in the bridge trash can one time. After then not eating until off watch till we got out of the weather. That thing rode terrible.
On a tug we did have a rough ride leaving Yakatat Alaska one time into strong westerly wind and sea Transiting the entrance outbound the seas were too high and steep the screw was out of the water too much to get enough bite to pull the barge out to sea against the wind. It was dark night and it was raining sideways but we could see that the seas ahead of the tug were dirty green colored from our lights. We let out some wire to get the tug in deeper water and got a better bite and got the barge across. Once we got out to sea there was another big swell from the SW. Had to turn the tug into the swell for the big ones then back into the sea for the smaller swell sets. I puked into a bunch of paper towels and threw it over the side. The deck of the barge had sand on it we we went aboard the next time.
Edit: I remember another thing about that night, we took one big roll and I heard a crash then a whistling sound. I went down to the galley and the TV, this big old thing which had it’s own shelf built into the bulkhead, was missing and there was a cloud of white fog-like smoke about four feet deep filling the galley. WTH? No time to wonder, had to get back to the wheelhouse. Next morning we found the TV jammed under the table. It has worked loose and dropped to the deck, hitting the handle of the big CO2 fire extinguisher setting it off.
