RE: heat index
Well, Pete, I gotta tell you.. my last patrol on the USCGC Comanche was a foreign fisheries patrol in the Pacific off of Northern CA, OR, and WA. When we left port, we went out about 25 miles and turned north.
Later on that day, the wind and seas picked up to the point where our progress was averaging - 2.5 knots for about 6 hours (yeah, negative progress).
At about quarter to one in the morning, I was on the bridge on watch as ships Navigator. I would do a "round" of weather sensors, a RADAR fix, LORAN "C" numbers, jot everything down, throw up, then wedge myself between the bulkhead (wall for you land-lubbers) and the RADAR indicator. We took a wave that put GREEN water (not the white frothy stuff on top of a wave, but the darned wave itself) up as high as the flying bridge. That was the first and last time (meaning that whole 4 hour watch cycle) that I was ever sick on a ship, Navy or Coast Guard.
Yup, it was nasty, and my last patrol before being transferred to NY City, Governors Island.
