A requirement has arisen at R.A.E. Aberporth to measure sea-state at considerable distances off-shore. To meet this requirement, it is necessary to define the surface profile of the sea at a given point to an accuracy of or - 6 inches under maximum peakpeak wave conditions of 8 feet. A system has been developed based on a stable platform in the form of a spar-buoy insensitive to wave-motion upon this is mounted a resistive type of electronic sensing unit to generate an electrical analogue of wave height, which is transmitted to a shore base by means of a telemetry link. This report describes the design features of stabilised spar buoys and the development of the electronic sensing unit ect. it gives experimental data from tests and outlines the development of an engineered system for operational use.
