This, sadly, is the best picture I could come up with (from one of the early Beam magazines) of the MV Valonia, which served in Irish Lights from 1950. This diesel-engined motor vessel was purchased from Trinity House as a replacement for the Nabro, which had served as relief vessel for lighthouses on the Cork and Kerry coasts. Captain J. Oscar O'Hehir, formally Captain of the Granuaile (the first one), was chosen to be her first skipper.
Other skippers during her ten-year tenure included Captain J. Coma, Captain Dermot E. Cormack, tragically drowned at Castletownbere in 1954, the exotically-named Captain Plato Harrison and Captain Herbert Greenlee.
Four years before the Valonia was sold to David MacBrayne, the Hebridean ferry company, a mysterious incident occurred on board the vessel, in September 1958. The story was related in the Irish Lights staff magazine, date unknown. The first nine words of the report, in particular, made my hair stand on end.
