Abstract

1425573 Pumping water from boats DEFENCE SECRETARY OF STATE FOR 18 June 1973 [21 March 1972] 13091/72 Heading B7M [Also in Division F1] A single seat inflatable survival dinghy has a pump chamber 1 formed between the two layers 2, 3 of a double layer floor. One way valves 4 and 5 lead to the interior and exterior of the dinghy, and the pump is operated by using a handle 9 to expand and contract the chamber. Resilient reticulated foam inserts 6, 7, 8 bias the chamber to its expanded condition with such a force that the floor in the region of the pump can be depressed by acting on the handle 9 while the chamber 1 remains expanded. The pump can thus always draw water from the lowest point of the dinghy floor. The pump is located to lie between the thighs of an occupant so that ease of operation is assured.
