Humber station at Spurn Point is a full time RNLI station.No, its at Waterloo Bridge on the Thames.
"Established in 1810, Humber is the only lifeboat station with a full-time crew and it has carried out some outstanding rescues during its 200-year history. The crews have been awarded 33 medals for gallantry."

They also helped me out once when I found myself short on fuel there. So top blokes!
