The Ship's Key?
Well Hell Son, the Snipes keep it, usually in the oil shop or in main control. Check with the Oil King or the MPA...they'll know where to find it! They use it to open the grease locker wherein the Relative Bearing grease is stored . The special grease is often used to grease the special "water line" for use in the motor whale boat before coming alongside of the mail buoy. Saves wear and tear on the line. We even set the "Mail Buoy Detail" once when entering Norfolk shortly after our commissioning. I had seven eager young swabs in the detail too. They were all decked out in foul weather gear (It was winter in the North Atlantic after all!), kapoks, portable battle lanterns to find the damn thing in the waning twilight, and one even had his boat hook with which to snare the mail buoy as we came alongside, which is an alternative to putting the boat in the water if the mail bag isn't too full.
One word of caution though. In the far southern latitudes, near 'round Cape Horn, making up to the mail buoy can be a bit hard, especially in the summer. The reason is because that is the breeding season for the seabats. During breeding season, the seabats are as crazy as a virgin swab on his first overnighter in Subic!
The damn things go absolutely nuts, flying around the ship in droves, especially at night of course. Sometimes if you are really lucky, you can catch one!
We caught one once...had it in a box on the foc'sle. We showed the seabat to several of the new members of the crew too...after the bridge announced that we had caught one.
Damn...I do miss those days...
