_n_, _o_, _p_, _q_, _r_, _s_. The radii of the floor-sweeps, abaft the
midship-frame: those before the midship-frame are on the opposite side
of the line A F, to which they are all parallel.

1st R^d. 2d R^d. 3d R^d. 4th R^d. The diagonal ribbands abaft the
midships.

_t_, _u_, _x_, _y_. The same ribbands expressed in the fore-body.

It has been remarked above, that the horizontal plane is composed of
water-lines and ribbands; it also contains the main and top-timber
breadth-lines, or the longitudinal lines by which the main-breadth and
top-timber-breadth are limited in every point of the ship’s length. The
horizontal curve of the transoms and harpins are also represented
therein, together with the planes of the principal timbers; the cant of
the fashion-piece, the length of the rake afore and abaft, the
projection of the cat-heads, and the curve of the upper-rail of the
head, to which curves of the lower ones are usually parallel.


                       HORIZONTAL PLANE. Plate I.

B A C. The line of the ship’s length, passing through the middle of the
stem and stern-post.

B. The upper-end of the stern-post.

C. The upper-end of the stem.

B F. The length of the rake abaft.

D W X. The top-timber-breadth-line, or the line which limits the breadth
of each top-timber.

D F. The breadth of the aftmost timber at the taffarel.

B K. The wing-transom.

B L P. The horizontal curve of the deck-transom.

M M. The horizontal curve, or _round-aft_, of the first transom.

M N. The horizontal curve of the second transom: it is prolonged into a
water-line, N 8 7.

_k_ O. The horizontal curve of the third transom, which is also
prolonged into another water-line, O, _n_, U, _p_, Q.

_m_ O P. The plane of the fashion-piece, as canted aft.

⊕ W U. The plane of the midship-frame.

_a_, _b_, _c_, _d_, _e_, _f_, _h_. The planes of the timbers before the
midship-frame.

1, 2, 3, 4, 5, 6, 7, 8, 9. The planes of the timbers abaft the
midship-frame.

X X. The figure of the upper-rail of the head.

C Y. The projection of the knee of the head.

The Third horizontal ribband, is marked on the plate.

a a. The projection of the cat-head.

Thus we have endeavoured briefly to explain the nature and uses of the
principal draughts used in the construction of a ship, which
reciprocally correspond with each other in the dimensions of length,
breadth, and depth. Thus the plane of elevation is exactly of the same
length with the horizontal or floor-plane. The several breadths of the
timbers in the floor-plane and that of the projection are mutually
transferable; and the real height of the timbers in the projection,
exactly conforms to their height in the elevation. Thus let it be
required to transfer the height of the wing-transom from the elevation
to the projection:
