As an aid to the amateur designer in deciding on the proportions of his craft, the following table has been compiled, giving the elements of some of the best known boats. The first column gives the length on waterline, the second the beam at loadline, and the third the ratio of length to beam or L/B. The fourth column gives the distance of the midship section from the fore end of waterline, and the fifth and sixth give the proportions of fore body and after body. The seventh column contains the product of the length on waterline, beam, and depth from waterline to rabbet, giving an approximate comparison of the displacements. In order to compare the relative fullness of the various models on the waterline, the forward part of the waterline is divided in half, and a line K C, Plate I is drawn and measured. This line is called the "middle ordinate," and is greater as the waterline is fuller. Column seven shows the ratio of this middle ordinate to the extreme breadth of the waterline, the average being about .36. As a further comparison, a dividing buttock line v r, is drawn in the half breadth plan, parallel to the centerline, and mid way between it and the greatest beam. This line intersects the waterline in two places, r in the forebody, and v in the afterbody. The distance of each intersection from its respective end of the waterline, or the lines r s t v, are measured, and columns eight and nine give respectively the ratios of r s, to the length of forebody, and t v to the length of afterbody. By the aid of those three columns the waterlines may be run in readily in the preliminary drawing. All measurements, for the convenience of calculation, are in feet and decimals.
