Popis: In the previous report, the authors examined the potential of transfer of the skill of working a Ro-scull to traditional Indonesian outrigger canoe (hereinafter just called canoe). Since the "Ro-scull" has been primarily used in traditional Japanese Wasen boat, it is difficult to apply Ro-scull directly to canoe with the hull form different from that of Wasen. The authors intended to find from image analysis the way of working a Ro-scull of canoe in comparison with Wasen and the suitable way of working that. The authors also intended to search the impact of varied skill level to work a Ro-scull on the introduction of working a Ro-scull to canoe from the comparison among testees with different skill level. In consequence, the following became apparent: (1) the motion of working a Ro-scull of canoe is smaller than that of Wasen since a testee could not plant its feet firmly on a canoe floor because of narrower breadth than Wasen; and (2) as for the difference of skill level, there was no clear distinction by testee because of the narrow range in which the blade apex of Ro-scull moved.
