In this paper, the author proposes a new quick drawing process of the lines of under w ater form for the basic designs of merchant ships having block coefficient ranging between 0.65 and 0.80.With systematic hand work, this process needs less labour than the customary process.The key points of this process are as follows : -(1) Drawing the sectional area curve from standard series of sectional area curves with C_⦻ and l_<cb> corrections.(2) Picking up the offset points at standard size from the offset curves.(3) Drawing the body plan of actual size from standard size by means of the similar translation method.In this first report, the item (1) is described in detail, while the item (2) and the item (3) will be reported in the second report.Nomenclature.L=Length between perpendiculars B=Moulded breadth D=Moulded depth d=Designed moulded draught C_b=Block coefficient C_⦻=Midship coefficient C_p=Prismatic coefficient l_<cb>=Relative longitudinal center of buoyancy from midship v_<cb>=Vertical center of buoyancy from base line of sectional area curve
