BODY PLAN[COURSE OF CONSTRUCTION intersection of the bow plane tB with square station 2, and t2 is the projection in the sheer of the intersection of water-line 2WL with the same bow plane. The water-lines and diagonals in the half-breadth and the diagonals and bow and buttock lines in the sheer may thus be drawn as fair lines by the help of battens, and if the lines do not pass through all the points obtained by projection from the body plan, the sections in the latter are rubbed out and new ones obtained from the lines in the half-breadth. This process should be repeated until the curves in both plans are fair and the intersections correspond accurately with one another as the projections of points in space. No frame of the ship, however, is made to the curves of these water and diagonal lines, so that their true shapes are not required for any practical purpose except fairing the body. For the whole Contracted length of the ship, except about three to four twentieths at method of each end, space and labour are therefore saved and greater faking. accuracy is ensured by using the contracted method of fairing. In this method the ordinates of the half-breadth are set only from Ith to nth of their true distance apart, while the transverse
