Gord... It is entertaining. I reported as Chief Engineer of USS Ernest G
Small (DDR 838), shortly after she emerged from a long rebuild with lots
of new equipment. I couldn't find a record of the shipyard having
performed a new inclining experiment, so I persuaded the CO to let me Sally
Ship. He was a good-humored fellow who would sometimes stop the ship to go
fishing.
We lined up a goodly portion of the crew - deck gang, gunners, & snipes -
on the forecastle, quarterdeck, & fantail and I got on the ship's PA system
with a whistle. (I wanted to use the loud ship's whistle but the skipper
didn't want to bring down the wrath of the harbor.) I blew the whistle and
the crew ran from port to starboard (Not too far; the maximum beam of our
destroyer was only 39 feet.) Blow again, and they ran back to port, and so
on. We got the timing down quickly and the Ernie G took on a noticeable
roll at her sympathetic period, which I can't remember now but
I think was around 11 seconds.
The crew enjoyed it thoroughly. Sailors can get a little buggy after a
while at sea. There was a minimum of good-natured (?) elbowing and shoving,
and a few bloody knees. My calculations showed that the engineers at the
Bureau of Ships were pretty good because our stability remained ok. I was
told an aircraft carrier can do the same thing by driving trucks from side
to side, though I've never actually heard of it being done.
Perhaps now that you're a senior officer you can persuade the RCN to do a
little Sallying and spread the science.
An Alberg couple is pretty small beer compared to that, but it would be
nice to claim that my period is shorter than yours.
