Abstract
This study is to evaluate hydrodynamic performance evaluation between three kinds of inflatable kayaks, that is, a frame kayak, a needle knife kayak, and a v-hull kayak. In order to test, inclining and turning trial test are performed in the Ocean Engineering Basin. Also, a resistance test is performed with a reduced scale kayak in the circulating water channel. Consequently, First, the moment arm of a v-hull kayak is the largest with 132.4mm, but turning radius of one was the smallest of them. Second, the resistance of a needle knife kayak is the smallest with 71N, the center of gravity of one was the lowest with 0.128m of them, and then needle knife kayak occurs in a draft overall. Consequently, the v-hull kayak has had the advantages on restoring force and turning performance than others. The needle knife kayak has been more excellent on resistance and center of gravity than others.
