The leading aim of this paper is to explain with plain equations the relationships among the various particulars of Japanese fishing boats and then using these equations, determine a method for calculating the various particulars necessary in the basic design stage. Almost all the equations shown in tables 3 and 4 take tha form (1) Y=a+bX. In special cases, however, forms (2) Y=a+blnX and (3) Y=ae^<bX> are also assumed. Regression coefficients a and b are obtained by regression analysis and r^2_<xy> for all the equations are larger than 0.9. The procedure for calculating the various particulars of fishing boats is shown by the arrow diagram in Fig.1. First of all, calculate the full load displacement △_f and fish hold capacity FH from gross tonnage, then using △_f and FH as initial conditions, determine two sets of various particulars. The average values got from the two sets of data are the various particulars of fishing boat. The comparison between the average calculated value and that which is currently used for designing a Japanese fishing boat is shown in Fig.4. Eighty percent of the data is within a five percent range.
