To quickly assess the difficulty of the text, read a short excerpt:
43, let 154-164 be the frame lines in way of the boss and the recess, the shaft being arranged in the design drawings to leave the ship at 160. Let SL be a line drawn through the centres of shait, which is seen to incline both to the sheer and the half-breadth. Draw a diagonal plane through the centre of shaft about normal to the frame lines; this will be indicated by its traces with the plane of each frame shown dotted in the body. A straight line XY is drawn perpendicular to these traces. In ...the half-breadth X'Y' is drawn to represent the line XY, and by measuring along the traces from XY to (1) each frame, and (2) the centre of shaft, we obtain the lines shown in half-breadth, viz. HMN and S'L' (the expansion due to the run down of the shaft is ignored). WORK ON THE MOULD LOFT FLOOR 45 The amount of swell at 160 is settled according to the par- ticular design adopted, and the distance CA is set off from the centre of shaft. AB is drawn parallel to the centre of shaft ; the frame line must not approach the centre of shaft nearer than this.
