She was bought in September 1964 and renamed MV "Galaxy". She had a 50 kilowatt RCA ampliphase transmitter installed and an approximately antenna mast erected behind the funnel (though a height of was claimed for publicity purposes). She set sail from Miami on 22 October 1964 for England via Puerto Rico and Madeira. The ship arrived in the Thames Estuary on 19 November 1964. Radio Caroline's owner Ronan O'Rahilly warned Radio London that this anchorage might fall within British territorial waters. They responded by moving the ship to a position four and a half miles from Walton on the Naze, Essex, close to Radio Caroline South's ship MV Mi Amigo. Radio London later regularly advertised this position on air as 51° 47.09" N, 01° 20.55" E.
