The Humber lifeboat is the only permanently manned, full-time lifeboat in the country. Its coxswain, BRIAN BEVAN is one of the most decorated men in the RNLI's service. He, his six crew and their families live at the end of Spurn Point, a strip of land curving into the Humber. This series of six programmes looks at the life of the men who man Britain's busiest lifeboat. On average it is called out once a week. It will launch in any wind, at night, whatever the sea. But the weather the crew dread most is fog.
