Next deck over each end with a seat 12" wide nailed directly on top of the sides. Put in a seat, or thwart, 9" wide and 7/8" thick, next to the middle brace, as shown. Cleats can be nailed to the sides under this seat. This should be a fixed seat, nailed to the cross brace and to the sides of the boat, which will assist in stiffening the sides.
You can nail a gunwale strip, 2" wide by 7/8" or ¾" thick, on top of the sides and reaching from one end seat to the other, or you can put a somewhat smaller strip around the outer edge of the gunwale, which is quite as good a way. It is not really necessary to put any gunwale strip on so small a boat, but if omitted a cleat must be screwed on for the rowlocks (Fig. 409). If you put the gunwale strip on top, it will make a more workmanlike job to first plane the edges of the gunwale so that they will be horizontal across the boat, in the same way that you planed the bottom edges to receive the bottom boards.
Put the centre of the rowlocks about 12" aft of the centre of the boat, raising them an inch or so above the gunwale by means of a cleat (Fig. 416), as shown.
Fig. 416.
At a distance of about 28" from the bow, you can, if desired, put in a 6" thwart between the gunwales or a little lower, and in the middle of this thwart bore a hole for a small mast, putting below and slightly forward upon the floor a block with a smaller hole. Sailing does not amount to very much in a boat of this sort, but a small sail is often very useful when going before the wind and adds to the fun.
This makes a very useful and safe boat for a couple of boys for river or pond work.
If you wish to make a larger one you will have no difficulty after studying the process given above. The only difference need be in the dimensions.
For one 12' long you could make the beam at the gunwale (outside) 3' 6" and at the bottom 2' 10", the beam at the bottom of the ends (outside) 2' 10" (same as amidships)—the ends to flare upward at the same angle as at the centre, the boards for the sides being 14" wide.
