According to the statistics of fisheries in 1998, number of the fishing boats within 20 gross tonnages were 98% of all fishing boats in Japan, and the material which are built up of the hull were mostly FRP. The fishing boat has to perform many functions. The hull performances, such as to negotiate rough seas and economical to navigate, have to consider when make plan the hull design. In other words, lines of hull of the fishing boats are essential to understand and discuss for improving these abilities. The researches of hull form measurements have done by means of procedures, such as a level meter and pantograph. But difficulties are induced in handling these procedures, especially measuring in the shapes around stern and stem included sharp curves. The authors intend hull measuring by using laser telemeter. The purpose of this paper is to examine the accuracy of characteristics of this procedure in applying for hull form measurement.
