Abstract
In this research, the effects of oar vibration on boat speed and comfort in rowing were evaluated. First, the significance vibration difference by two types of boat oar to the handle part was observed by modal analysis. And then, the oar vibration transferred to the front end of a boat on the feature when turning oar blade in rowing. Therefore, it was clarified that the relation between the boat speed by GPS and the boat vibration had a negative correlation. Secondly, the boat vibration by two types of boar oar was different, and then the large catch vibration by a type of oar was observed. Finally, it was clarified that the vibration effects on the comfort in rowing by a subjective evaluation on the simulation test by using a shaker.
