For the line representing the bottom of the keel, fix upon a point 8in. below _the L.W.L., and draw a line right across the board; the vessel will now measure in height from the keel 12 in. at stem and stem, and at the midship section 10% in. To give the necessary rake to the stem, measure to the right of N0. 17 station a distance of 8% in., and through this point draw a line from top to bottom of the board, and at right angles to the load water-line; this line cutting the line of the deck determines the extreme length forward at this point. The form of the stem can now be struck in as shown in Fig. 79. The propeller aperture and the counter are next to be considered. The propeller aperture is to be 3in. measured fore and aft, and the counter is to be 5 in., measuring from the after end of the rudder-post; the forms of these are shown in Fig. 79. In drawing down the space for the propeller aperture, keep it as large as possible, in order to get into it a screw propeller of large enough diameter. To effect, this better, the body, or stern-post, and the rudder-post are made in one piece. The inverted half plan, Fig. 80, known as the halfbreadth plan, shows the longitudinal transverse section of the vessel at the load water-line, and at other water-lines parallel to it. Fig. 81 is the body plan; the right-hand portion of the middle line Z Z sets forth the curve of every station from N o. 17 to...
