Naval ARCHITECTURE (continued)

With regard to the qualities required in the construction of a ship, to fit her out for the various purposes of navigation, the reader is referred to the article BOTTOM.

We shall now proceed to explain the sheer draught, or plane of elevation, of a sixty-gun ship; wherein we have been attentive to make the same letters refer to the same objects, as in the explanation of the PIECES, as above; at least when the same objects are in both figures. This conduct we shall invariably pursue throughout this work, although it seems to have been forgot by our predecessors. Thus in all the plates of ship-building, the keel, whether separate or joined, is represented by A, the stern-post by B, the stem by C, the beams by D; unless where those objects do not all appear, and then something else is placed instead thereof. Thus in plate III. of the deck, where the keel cannot be seen, the main hatchway is represented by A, as not being inserted in any figure wherein the keel appears.

QR. The main skeeds, for hoisting in the boats clear of the ship's side.

L QZ. The main wale, with it's sheer afore and abaft.
