Abstract

The design and implementation on a Small Waterline Area Twin Hull (SWATH) vessel of a complete system for measuring the directional distribution of wind waves and the concomitant fluctuations of air pressure and wind speed immediately above them are described. Data taken with the system on board the Canadian Coast Guard Ship Frederick G. Creed during the 1999 Shoaling Waves Experiment (SHOWEX) are used to calculate the wave-supported fluxes of momentum and energy between the air and the sea.
