Abstract
In this research measuring resistance of sailing yacht, side Force and yaw Moment using resistance test, force measuring test at various combinations of heeling and leeway angles & Keel test when Keel attached and wasn't attached on the bottom of hull part. When sailing yacht is upright condition, measuring difference of side force when keel attached and wasn't attached on the bottom of hull part and comparing Keel's side force measured by Keel test. From this result searching correlation between hull and Keel. And case that leeway angle is 10° and heeling angle 20°, measuring flow of wake by PIV(particle Image Velocimetry) method when Keel attached on the bottom of hull part and Keel is alone in order to verify whether ignore of correlation between hull and Keel is possible when there is leeway angle and heel angle as well as sailing yacht is upright condition. From these results gaining conclusion of ignore of correlation between hull and Keel is possible. Therefore researching Hydrodynamic Force and Fluid Flow Characteristics change of 3 types of Keel using PIV(particle Image Velocimetry) method and Keel test. 3 types of Keel were Fin Keel, Bulb Keel, Winglet Keel.
