Mine Host at Amble, When Amble's 44ft Waveney class Margaret Graham launched on 5 December 1989 to act as a safety boat for some RN divers about to explode a war-time mine she also found herself acting as a different kind of mothership - to a local bottle-nosed dolphin! Worries had been expressed about the safety of the dolphin, which has made its home in Amble Harbour, and so after delivering the divers to the area of the mine Margaret Graham set of for the harbour area to try to attract the dolphin's attention and keep him in a safe area while the SOOlb mine was detonated.

The mission was succesful, much to the delight of the spectators and the local media, and the dolphin found the lifeboat interesting for long enough to avoid giving him a severe headache..
