Southend-on-Sea, Essex. At 11.15 on the morning of the 26th of April, 1959, the coastguard told the honorary secretary that a motor barge needed help one mile north-east of the North Knob buoy. At 11.36 the life-boat Greater London II (Civil Service No. 30) was launched. The sea was rough, a south-westerly wind of nearly gale force was blowing, and the tide was flooding. The weather was cloudy with squally showers. A helicopter also took off, and her crew gave the coxswain a new position of the casualty by very high frequency radio-telephone. This placed the barge three miles nearer to the life-boat. The barge Glenwood of Rochester was found with two men on board. At their request the life-boat towed the barge to the Southend jetty, arriving at 3.30. Property salvage case..
