Series tests were carried out to investigate the relations between hull form and wave resistance obtained by wave pattern analysis. The eleven models selected were composed of four series, namely ∇/ L ³-series, B / d -series, C _p-series and l _cb-series. The hull characteristics of these models are as follows : (1) Water lines meet with base line tangentially at both ends. (2) Frame lines are consisted of Lewis forms. (3) Sectional area curves are equivalent to Tchebycheff's functions. (4) Models are symmetric about midship except for l _cb-series. The wave pattern measurements were performed simultaneously with ordinary resistance tests, and wave data were analyzed by the method of J. N. Newman. The test results of wave resistance, residual resistance and sinkage for each series were presented in non-dimensional form. Form factors were derived from these results by deducing wave pattern resistance from residual resistance. Some consequences of experiments were compared with the results of linearized theory, which may be usefull information for the basic hull form design.
