I remember back in the late 70's doing Flank Speed runs back and forth through the Straits of Messina one night. We were doing war games with subs best I remember and were not escorted. A carrier at Flank Speed you can feel it throughout the ship. Under normal Full or lower you don't feel the rise and fall or list but you sure do at Flank and you can also hear the turbines from Hanger Deck and lower.
I think I have probably told you this before (hehehe...doing the same thing with Freepers now that I do with my wife and friends “I’ve probably told you this before”...:)
On my first transatlantic crossing out of Norfolk, we left late in the day, and I hit my rack. I woke at the early hours of the morning around 0200-0300 I think, and the entire compartment was shaking in time with a thudding sound. It was going “WHAM WHAM WHAM WHAM WHAM WHAM” about 240 times a minute. (That might mean something to you, but when I reconstruct it today, I remember the sound, and can time it for 24 “whams” in six seconds multiplied by 10.
I got out of my rack and went back to the fantail, and there was a mountain of white water behind the ship!
You probably know this-was that “Wham” one rpm, or was it one of the screw blades making the noise (so divide 240 by the number of blades on the screw?) I don’t know how that works...I always just assumed one wham was an RPM.
