Pictured on the day they were loaded onto 'GRANAT', IMO 9004499, at Felixstowe on 01/04/2013.
There were three of these "Hauk" Class, ex Norwegian Navy, patrol vessels aboard; one foreward, & these two aft.
I have identified the foreward vessel as ex P988 Terne, but these two are proving more difficult.
All three patrol vessels have been purchased by Nigeria and were on route to Lagos.
"Granat" remained alongside for a few days after loading, due to being detained by Customs over paperwork irregularities.
