water pressure and a righting moment force against its inside skirt surface as the gas pocket rises also the gas pressure increase in the moment due to a more horizontal hull surface area for the gas pressure to work against resistance to heaving motions will be increased both in height and velocity because of the dampening effect of the gas pockets to the heaving force against the ships 39 hull partial protection from hull damage will be afforded by the surrounding hull skirt with its attendant gas pockets from underwater or surface objects such as mine explosives and other objects better operating cost efficiencies as a result of greater weight carrying capacities and or increased speed will be afforded due to less friction drag exerted by the water particles on a lessened area of the skirted hull of the moving ship as compared with a non skirted hull the underwater hull and skirt surface area in contact with the water will be reduced because of a smaller draft depth and also the gas pockets the water gas friction will be very minor compared with the water hull friction when the ships apparatus is active as addressed below air compressors 14 or compressed gas bottles 15 diagrammatically shown in general by fig3 coupled to sea pressured gas pockets 8 via pipe lines 16 air accumulator 17 pressure regulator 18 stop check valves 19 shut off valves 20 control valves 21 relief valves 22 and pressure gauges 23 inflates the gas pockets until they are full of gas.
