強風下における小型船のキャンバスによる受風効果

抄録

For small vessel, it is important to run into the nearest harbor as soon as possible when the sea state deteriorates. However, under such condition, it is difficult to keep her course especially when scudding with strong wind. Therefore the authors proposed the method to strengthen course keeping ability by spreading a canvas around the flying bridge. In order to verify the effects of a canvas, model experiments were carried out at the wind tunnel with water tank to measure wind forces and moment and numerical investigations were conducted using these experimental data. The results were summarized and presented in terms of deviation ratio.
