About 98% of fishing boats in Japan are registered as less than 20 gross tonnages. In such a small fishing boat, the hull performance standards have not been examined enough, because the data of hull forms are unpublished in general from the production site in major manufacturer and local shipyard. To understand and discuss for improving of hull performance of fishing boat, lines of hull which are now used in the surface of the sea are essential. The authors examined the accuracy of characteristics of laser telemeter by the distance to object and measurement accuracy by angle. And these examinations confirmed to measure accuracy according to the condition in setting the range of the measurement. In consideration of such a result of the accuracy characteristics, the measuring method of hull of small fishing boats by laser telemeter is considered in this paper. In addition, the effectiveness of the examined measuring method is able to be verified by measuring a small fishing boat.
