Portable Operating at Sea

Maritime Mobile (/MM)

When holidaying on cruise voyages, I have operated Maritime Mobile from various ships sailing European and international waters.

Fred Olsen Cruise: MS Braemar (July 2008)

Between 13th and 24th July 2008, I operated /MM aboard the Fred Olsen ↗ cruise liner MS Braemar ↗.

The voyage sailed from Southampton down the Atlantic coast, through the Straits of Gibraltar, and across the Mediterranean to Rome. Because the vessel was registered in Nassau, Bahamas, and navigated international and various territorial seas, a sequence of CEPT and maritime mobile callsigns were used.
