The patent application relates to a method of determining the watertight integrity of the floatation hull of air cushion vehicles, ground effect machines, and hovercraft by measuring the differential air pressure between the air pressure in the hull or individual airtight floatation compartments during operation of the vehicle and the air pressure in the static condition. Under normal operating conditions, the compartment air pressure-atmospheric pressure differential is the same as when the vehicle is static. If a leak occurs in the hull, the cushion air pressure, higher than atmospheric, will enter the hull or compartment causing therein a rise in pressure above atmospheric, detectable on differential pressure gauges. Continuous surveillance may be maintained by relaying the information to an annunciator or alarm system at a control station.
