Over the lid blankets are folded, making a divan during the day and a bed at night. The top bunk is made like the frame of a cheap cot, but in place of being upholstered it has a strong piece of canvas stretched across it. This bunk is also hinged to the back of the cabin, so that when not in use it can be swung up against the roof and fastened there as the top berth in a sleeping-car is fastened. Four 4-by-4 posts can be bolted to the side-support at each corner of the bottom bunk; they will amply support the top bunk, as the legs do a table-top when the frame is allowed to rest upon their upper ends. This makes accommodation for two boys, and there is still room for upper and lower side bunks, the cabin being but six feet wide. If you put bunks on both sides you will be rather crowded, it is true, but by allowing a 1-foot passage in the middle, you can have two side bunks and plenty of head room. This will accommodate four boys, and that is a full crew for a boat of this size. On board a yacht I have often seen four full-grown men crowded into a smaller space in the cabin, while the sailormen in the fo’castle had not near that amount of breathing-room. [Illustration: FIG. 122.] Figs. 118, 119, and 120 show A More Simple Set of Plans. Here the cabin is built on top of the upper deck, and there are no bottom-ribs, the uprights being held in place by blocks nailed to the bottom of the boat, and by the deck of the boat. This is secure enough for well-protected waters, small lakes, and small streams. Upon the inland streams of New York State I have seen two-story house-boats, the cabin, or house, being only a frame-work covered with canvas. One such craft I saw in central New York, drifting down-stream over a shallow riff, and as it bumped along over the stones it presented a strange sight. The night was intensely dark, and the boat brightly lighted. The lights shone through the canvas covering, and this big luminous house went bobbing over the shallow water, while shouts of laughter and the “plinky-plunk” of a banjo told in an unmistakable manner of the jolly time the crew were having. Canvas-Cabined House-Boat. If you take an ordinary open scow and erect a frame of uprights and cross-pieces, and cover it with canvas, you will have just such a boat as the one seen in central New York. This boat may be propelled by oars, the rowers sitting under cover, and the canvas being lifted at the sides to allow the sweeps to work; but of course it will not be as snug as the well-made American boy’s house-boat, neither can it stand the same amount of rough usage, wind, and rain as the latter boat.
