One of the authors has been studying the berthing of ship theoretically as well as experimentally since 1957. The proto-type of this water pressure gauge -hand made- was used to measure the pressure on the hull of ship model in still water. The gauge was improved and refined so as to measure the wave forces in waves. In this paper, details and characteristics of the gauge are described. Its ordinary pressure range and natural frequency are about 3gr/cm^2 and 240Hz, respectively. Both the values may be chosen arbitrarily by changing the thickness of a thin plate with strain gauges and the gain of an amplifier.
