is to fit in the space, A, B, D, C of the centre-piece, Fig. 114. There is to be a 1-inch plank at each end (see Fig. 117), next to which the side-supports at each end of cabin fit. The supports are two-by-twos; so, allowing 1 inch for the plank and 2 inches for the upright support, the next pair of ribs will be just 3 inches from A B, Fig. 114, of the centre-piece (see Figs. 116 and 117). The twin ribs at the forward end of the cabin will be the same distance from D C, Fig. 114, as shown in the plan and elevation, Figs. 116 and 117. This leaves five pairs of ribs to be distributed between the front and back end of the cabin. From the outside of each end-support to the inside of the nearest middle-support is 2 feet 6 inches. Allowing 2 inches for the supports, this will place the adjoining ribs 2 feet 8 inches from the outside of the end-supports. The other ribs are placed midway between, as may be seen by the elevation, Fig. 117.
at the forward end of the cabin, which are placed flush with the line D, C, Fig. 114 (see Figs. 116 and 117). The two pairs of ribs in the bow are spaced, as shown in the diagram. This description may appear as if it was a complicated affair; but you will find it a simple thing to work out if you will remember to allow space for your pump in the stern, space for the end-planks at after and forward end of cabin, and space for your uprights. The planks at after and forward end of cabin are to box in the cabin floor.
by sliding it over the rollers, which will not be found a difficult operation.
--two in the bow under the hatch and one under the rear bunk--but if it is deemed necessary the space between-decks, at each side of the cabin, may be utilized as lockers. In this space you can store enough truck to last for months. A couple of doors in the plank at the front of the cabin opening, under the deck, will be found very convenient to reach the forward locker in wet weather.
is a triangular piece of 2-inch board, made to fit exactly in the middle of the stern, and had best be nailed in place before the boat is launched (see Fig. 117). The keel must have its bottom edge flush with the bottom of the boat, and a strip of hard-wood nailed on the stern-end of the keel and bumper, as shown in the diagram. A couple of strong screw-eyes will support the rudder.
