In the South-East Asia countries and Japan located in the northwestern part of the Pacific, there are many rowing fishing boats used for small-scale coastal fisheries. Many of such being boats are made from wood and are decreasing every year due to the material shortage and the aging of ship carpenters besides the deterioration of boats. Ro-scull is traditional devices in Japan. It is the traditional propeller for small boat using hydrodynamic lift force. It runs the boat very gently and economically. However, the wooden Wasen has almost disappeared. Whereas FRP boats partly inheriting hull form from wooden Wasen are replacing such Wasen. Meanwhile many of rowing fishing boats in subtropical and equatorial zones is dugout canoes or outrigger canoes, which also are decreasing in number and gradually fading away for the same reason. Indonesia outrigger canoes are propelled mechanically, but many fishermen want to change the propelling method to human power due to rising fuel oil prices. On the other hand, in Japan the small fishing boats are used to be propelled by Ro-Scull. Based on this reason the author tried to find the potential of applying Ro-Scull of Japanese Wasen to Indonesian outrigger canoe. The author compared the hull form of canoe to the Japanese wasen and examined the possibility of applying Wasen’s Ro-scull to outrigger canoe in order to transfer the skill of working Japanese wasen to Indonesian outrigger canoe. Therefore, it was found the enhancement of stability was necessary by mounting a floating structure on the after part of canoe to reduce oscillation in addition to Rogui and Rodoko, a bed to which Rogui was mounted. Rogui is a pivot for Ro-scull and becomes a fulcrum when wasen is propelled by Ro-scull. Chapter 2 : This chapter discussed about on statistical analysis of hull type and characteristics of Indonesian outrigger canoe and Japanese Wasen. Indonesia is divided into five major islands, such as Sumatera, Jawa, Kalimantan, Sulawesi and Papua. The research areas are Jawa, North Sulawesi (Manado, Minahasa and Sangihe), Gorontalo province, South Sulawesi (Ujung vii Pandang), Molucca and Sulu Island (Philippines). The material consists of the data on 604 Japanese Wasen and 492 Indonesian Canoes (Jawa, South Sulawesi, North Sulawesi and Sulu Island). The outriggers of Indonesian double-outrigger canoes (Jukungs) are sophisticated in
