The transom (E) is sunk into the stem piece (D), as shown in [Fig. 2], and secured at right angles to it by two screws at e1 and e2. The whole stem piece can now be fixed to the keelson (a b) by two strong screws at the points d and d2, [Fig. 2].
The next part requiring attention is the amidships (section F of [Figs. 2] and [4]; see also [Fig. 8]); this can be made of deal 7⁄8 in. thick, 2 ft. 9 in. wide at the top, and 1 ft. 3 in. deep. The outline beginning at f1 is for 6 in. straight and at right angles to a line drawn across the boat, then it follows a curve of 7 in. radius whose centre is at f2 to the point f3, which is 1 ft. 11⁄2 in. below the top and 1 ft. from the centre line: from this point the outline runs straight until it joins the centre line at 1 ft. 3 in. from the top. A mortise 1 in. wide and 11⁄2 in. deep must be cut in the centre of this section at the bottom, in order that it may fit accurately over the keelson and at right angles to it, in which place it is fastened by a strong screw passing through the keelson from beneath. As its name implies, this section must be exactly amidships.
The notches and spaces are, beginning at f1, (11⁄4 in.,) 23⁄4 in., (11⁄4 in.,) 23⁄4 in., (11⁄4 in.,) 23⁄8 in., (11⁄4 in.,) 23⁄8 in., (11⁄4 in.,) 27⁄8 in., (11⁄4 in.,) 23⁄4 in., (11⁄4 in.,) 21⁄4 in. mortise for keelson in centre. The other side is the same.

Amidships Section
The middle of this section is cut out for the sake of lightness, as shown in [Fig. 4], and a seat 7 in. wide, and 4 in. from the top, is fixed across it.
Under the centre of the seat an upright support (f4) is fixed, of the same width as the seat, being also made to fit over the piece F and rest on the keel.
The seat must be screwed firmly into its place, so that the future rower may feel himself in no danger of being precipitated to the bottom of his boat among the débris of a broken seat.
