on the wind screen, unless the pontoon be moored in a place where the current is very strong, would always have the effect of keeping the pontoon head to the wind. If it be necessary to moor the pontoon in a position where there is a strong cross-current, it might be found desirable to drop a couple of kedges, one from each side, at the stern, from which lines could be made fast on the pontoon, which could thus be made to lie in any desired direction. FEBRUARY 19, 1920 to receive the incoming flying boat. The latter would taxi up to the entrance at the aft end of the pontoon, and be man- handled on to the cradle, where it would be suitably secured. Compressed air would then be blown into the top of the four lifting tanks from the receiver, and the water driven there- from, control being maintained by the water valves pre- viously mentioned. These valves are operated by hand levers situated in the house. The pontoon would thus rise, The Bristol mooring pontoon as it appears floating on the ^ water, with a ^ flying-boat hull _ "in dock " 55 SS 55 The pontoon is operated by means of compressed air, and for this purpose a small petrol-driven air compressor would be provided in the house mentioned, with the necessary receiver connected by pipes to the ballast tanks. The pontoon would be sunk by admitting water through convenient valves in the ballast tanks. She would then be in a position carrying the flying boat with it, which would thus be left high and dry. The same compressed air plant could be utilised to blow petrol or fresh water on to the flying boat and also for pressing water out of the ballast tanks through fire hydrants preferably arranged on the two aft ballast tanks.
