Shipboard Evaluation of Drag Coefficients for the Marine Regime

A considerable amount of overwater dissipation and wind profile data obtained from shipboard measurements were interpreted relative to the representation of the drag coefficient. Drag coefficients were interpreted relative to wind speed, wave and hydrostatic stability influence. It was noted that at all wind speeds and particularly at low wind speeds, drag coefficient values are larger when large waves are present. Likewise, it was noted that in unstable conditions drag coefficient values increase as neutral conditions are approached.
