Begin by drawing a straight line with pencil down the exact centre of
what will be the deck; continue it down the part that will be the stern;
then carry it along the bottom of the block, where the keel will be, and
up the front part, or bow. If this line has been correctly drawn, the
end of it will exactly meet the place where you began to draw it. On
the correctness of this line much will depend; therefore it is necessary
to be careful and precise in finding out the centre of each surface of
the block with the compasses. Next, draw a line on each side of this
centre line (as in the accompanying diagram), which will give the
thickness of the keel and stern-post. Then on the upper surface of the
block draw the form of the boat to correspond with the bird's-eye view
(Figure 4, on page 82) already referred to. Then draw _one-half_ of the
stern on a piece of thin card-board, and when satisfied that it is
correct cut it out with scissors; apply it to the model, first on one
side, and then on the other side of the stern-post. By thus using a
pattern of only one-half of the stern, exact uniformity of the two sides
is secured. Treat the bow in the same way. Of course the pattern of
the bow will at first be drawn on the _flat_ surface of the block, and
it will represent not the actual bow, but the thickest part of the hull,
as seen in the position of Figure 3, on page 82. After this, turn the
side of the block, and draw the form represented in Figure 1, page 82,
thereon, and mark _on the keel_ the point where the stem and keel join,
and also where the stern and keel join. This is necessary, because in
carving the sides of the boat these lines will be among the first to be
cut away. The next proceeding is to cut away at the sides and bottom of
the block until, looking at it in the proper positions, the bow
resembles Figure 3, and the stern Figure 2, above referred to. This
will be done chiefly with the gouge, the chisel and spoke-shave being
reserved for finishing. Then saw off the parts of the bow and stern
that will give the requisite slope to these parts, being guided by the
marks made on the keel. In cutting away the upper parts of the bow and
stern, be guided by the curved lines on the deck; and in forming the
lower parts of the same portions, keep your eye on your drawing, which
is represented by Figure 1.
