Abstrak : Main size determination (principal dimension) ship by use of statistical methods (SPSS) can also be developed, this method go upon counts to get ship fundamental measure base fundamental measure statistical bound fast already be built. Acquired arithmetic formulas bases analisis regressions to statistical of numeric bureau register books Indonesian (BKI). This writing intent to determine ship fundamental measure on early design phase (preliminary design) by use of statistical method (SPSS). Type bounds fast that is used in this used in this case study is roll on roll off’s ship (RO-RO). Expected target is size main ship which accomplish maximal tech criterion. Analisis’s result statistic in inscriptive in points out that exist correlation that really significant among parameter among parameter tonnage’s gross RO-RO’S ship with elongated parameter among lines straightening (LBP) = -74,259 + 18.8411n (GT) with r = 0,944, broad bounds fast (B) = 4,833 + 2,587 ln (GT) with
