Bamenda Palm
United Kingdom of Great Britain and Ireland
The freighter accidentally rammed a Romanian Fish factory ship in Carrick Roads, Falmouth, Cornwall in a Force 9 Southerly gale. The anchorage was very crowded with many vessels sheltering from the storm. A major disaster was averted because the bulbous bow punctured the fishing vessel in the fish hold. After 5 days repairs, Bamenda Palm was seaworthy to continue the voyage to West Africa.[24]
