Humber, Yorkshire - At 3.21 p.m. on 13th September, 1966, it was seen that a cabin cruiser was being towed towards Spurn Head by the pilot launch. They were kept under observation for some tune, and as there was a heavy swell running and nowhere to shelter, it was decided to launch the life-boat. The life-boat City of Bradford III was launched at 3.30 in a strong west north westerly wind and a rough sea. It was four hours after low water. As this was a busy period for the pilot launch she took over the tow of the cabin cruiser Petan at the military pier, and proceeded to Grimsby. Just before they entered the harbour the Petan's mast was carried away when the mast stays parted under the heavy pitching. She was moored safely without further mishap and the life-boat returned to her station, arriving at 5.50..
