Whenever I travel on a Mickey Mouse cruise ship, I carry this.

Smart move, a personal IR strobe, and epirb would be a good ideal to.

P.S. You may remember that my late Father-in-Law navigated 1800 miles
in an open lifeboat after being torpedoed at the end of WWII. They
had a sextant, tables and charts, and Movado wris****ch. Dave claims
they always knew where they were, and only missed Tobago because they
were afraid of going in at night. They ending up near Curacao, having
sailed from 800 miles west of Dakar.

Yes it was an epic story, I still like the baseball liberty story best
:0)

Check out this lifeboat story:

Funny read, situation... and sounds like a trip of a lifetime.
