The Ice Hole works equally as well with Polar Bears. I was in the Navy for 20 plus years and once when we were thousands of miles from no where, we had a terrible infestation of Vampire pirates. The CO was a wise old seaman and had dealt with this before, He ordered all the engine room crew, (Snipes) to hang their socks on the port yardarm.

The poor old Signalman had no other choices other than just hanging it over the fan tail, (Stern).
