Comparative Analysis of the Performance of Boats According to Shapes

Abstract

The present study compared the performances of three types of boats of different shapesto develop boats that are more efficient for the activation of water leisure. Three types of inflatable boats were used in the experiment: kayak boat A, which is relatively wide; kayak boat B, which is relatively long; and boat C, in which a frame was installed. The paddles used in the experiment were 230 cm long and made of plastic by the same company, and six healthy male university students participated in the experiment. In the experiment, boat C, which is an inflatable boat with an added frame, showed the highest straight sailing speed, leading to the conclusion that the straight sailing performance of boat C is superior to that of boats A and Bwithout any frame. Boat C was greater in stability and rotation capacity compared to the other boats, although the differences were not statistically significant. The reason why boat C, which is a framed boat, could sail faster than other boats is considered to be based on the fact that the experimental subjects psychologically judged that boat C was safe because its lateral rolling was lesser than that of the other two boats and it took stronger and faster stroke motions.
