碩士 === 國立高雄海洋科技大學 === 造船及海洋工程研究所 === 106 === It is very important to implement marine science education. To improve ocean literacy , the Ministry of education promotes many marine courses. One of them is canoe building. The course starts with knowledge of shipbuilding, simplifies com-plex and abstracts scientific knowledge. Participants can experience the canoe building in a short time and paddles the canoe when it is completed. It further in-spires students’ knowledge of oceanic science and marine humanities. In this study, we used the StarCCM+ numerical analysis software to analyze the resistance of the hand-made canoe. There are two different loading condition: a sin-gle person of 105Kg, and 2-person of 185kg. Different pitch angles, eg. even keel, trim by stern and trim by bow are analyzed. We aim to find the most padding ar-rangement. Then through analysis of hydrostatic curve. We used the empirical for-mula 2/3D as the center of gravity as a benchmark. Then we calculated 1/2D less than the empirical formula and 3/4D higher than the empirical formula for compari-son. We can obtain the best stability of the canoe. The analysis provides the safety measure for the hand-made canoe teaching. This research found, trim by stern has the least resistance, and trim by bow has the greatest resistance. The stability of the even keel condition is the best, having the largest restoring arm GZ. The larger the restoring arm GZ is, the larger the relative stability range is.
