At 4.30 p.m. on 2ist August, 1966, it was noticed that a cabin cruiser was broaching to in broken water on the North Tail. The life-boat Louisa Anne Hawker proceeded at 4.45 in a moderate westerly breeze and a choppy sea. It was low water. A helicopter was also alerted, but the cabin cruiser cleared the rough water without assistance. The life-boat then went to the aid of a small boat aground off Airy point. A life-boat crew member swam across with a tow line, and the small boat was towed clear of the breakers. The life-boat returned to her moorings at 7.45..
