Another safety first for the RNLI: The 52ft Arun which will soon be going on station at Fishguard is the first lifeboat to be fitted with a radar scanner which has been made watertight. During her righting trials at Cowes on May 5, the Arun was capsized with her Decca 150 radar operating. The radar automatically switched off before the scanner entered the water. Then, after the boat had righted herself, the radar was switched on again manually and a picture was once again obtained on the display..
