[1] In December 1963 Fredericia was sold to Cross Channel Container Services Limited, Greenore, County Louth, Ireland.

She passed Land's End on 25 March, at which time she altered course and made passage through the English Channel and entered the North Sea where she anchored off Felixstowe.

On 28 March, Radio Caroline began regular broadcasting at noon on 1520 kHz (announced as 199 metres in the medium wave band) with the opening conducted by Simon Dee.

[1] However, the original ship's bell from Fredericia was saved, being on display for many years at the Viking Longhouse, Peel, Isle of Man.

Although the ship's bell remains in private ownership, it was displayed at the Radio Caroline 60th Anniversary Lecture at the Mitre Hotel, Ramsey, Isle of Man, in August 2024.
