This paper presents a simple and practical method of obtaining the estimate of total investment costs for Turkish anchovy purse-seiners, designed by “traditional methods”. It is intended as a guide to fishing vessel designers, builders, owners and others concerned at the beginning of a new project who may wish to know the investment, and how it changes with alterations to principal design variables, such as main dimensions, and power. The method does not supplant more refined techniques used for professional cost estimators at later stages in the design, but it may be useful in circumstances where cost estimating expertise or actual shipyard costs are not immediately available. Fishing vessels discussed in this study are of 20 to 40 m long with an engine power of 300 to 1100 HP. It has been found that for the year 1997 total investment costs varied in the range from US$ 265000 to 532000, with an average value of US$ 391000. The average values for the proportions of investment cost components were found to be 25% for vessel production, 27% for machinery, and 48% for fishing gear and equipment cost.
