A series measurement of coastal fishing boats (small purse seiners) has been made in North Sulawesi province, Indonesia. The goal of this study is to clarify the physical characteristics of the small purse seiners in North Sulawesi. First of all we examined the boat form of the purse seiners and practical conditions under fishing operations. Based on the data, the characteristics such coefficient of fineness and the boat's stability were calculated. Typical fishing boats in Indonesia have conventional round hull shapes with a long bar keel. Purse seiners in North Sulawesi have different characteristics in every region, especially for principal dimensions and boat's designs. The results of the analysis are as follows: the boat types are relatively slim around the hulls and have the round shape under water, stability values are relatively small, and the cluster based on the principal dimensions and the coefficient of fineness has been categorized into two groups and three classes.
