GENERAL REMARKS ON THE HULL, SPARS, AND SAILS.-DEFINITIONS.
Wooden ships are usually built on stocks and launched on ways, which are inclined planes leading to the water’s edge. Sometimes vessels are built in docks, which are artificial basins with level floors, shut off from outside waters by gates or by a single dam known as a caisson. These gates are water-tight and can be opened or closed; the dock is supplied with means for pumping out the water or letting it in.
The lowest fore and aft piece which forms the foundation of a ship is called the keel (Plate 1, No. 1). It is of live-oak, or elm, and made of several pieces, the joints of which are known as scarphs.
To receive the edge of the first row, or strake, of outside planking, called the garboard strake (2), the keel is scored throughout its length, the score being styled a rabbet (3).
To protect the main keel from injury in grounding there is fitted under it a false keel (4), bolted on after the bolts which secure the frames to the main keel are clinched.
The forward end of the ship is formed of the stem (5), usually of live-oak, and inclining forward from the keel. A rabbet, similar to the one scored in the keel, is cut into the sides of the stem and receives the forward ends of the outside planking, which are called the fore hood-ends.
The stem is backed and strengthened by the apron (6), placed abaft it, and by the deadwood (7).
Deadwood consists of timbers that fill the spaces where, owing to the shape of the vessel, the floor-timbers have to be discontinued.
Inside of the forward deadwood and the apron is the stemson (8), a large knee which joins the apron to the upper part of the deadwood.
The after-end of the ship is bounded by the stern-post (9), usually of live-oak, which stands perpendicular to the keel or slightly inclined aft. It is fitted like the stem with a rabbet on each side to receive the after-ends of the outside planking, or after-hoods, and it is strengthened by the introduction of a stern-post knee (10), inner post (11), and the after-deadwood (12). Above the latter is the after-deadwood knee (13).
|Screw vessels have generally two stern-posts; the after one, which carries the rudder, is called the rudder-post.The joining of the stern-post to the keel is effected by tenons and bolts.The frames (14) form the ribs of the ship. They stand mostly at right angles to the keel and each is formed of two parts joined together, each part being in itself made up of several pieces. The lowest portions of a square frame are called the floor-timbers; above these come the futtocks, then the long or short top-pieces. The starboard and port side of each frame form one continuous piece.|
Where, owing to the form of the ship, the frames do not stand at right angles to the keel, they are called cant frames.
The following parts of the ship serve to secure the above-mentioned portions together and give the structure stiffness and strength; viz., the keelsons, breast-hooks (15) and stern-hooks (16), outer and inner planking, beams (17) and diagonal braces.
The main keelson (18) is a fore and aft timber which is laid directly over the keel on the floor-timbers and may extend beyond the latter and over the deadwood, forward and aft. The keelson is bolted through frames, keel, and deadwood. There are usually additional keelsons at each side of the main keelson, known as sister keelsons (20). There are also boiler or bilge keelsons to support the boilers (19). Bilge-keels are exterior keels bolted on to the bottom of the ship on either side of and parallel to the main keel, and at some distance from the latter, to prevent rolling in vessels of certain form.
To hold the two sides of the ship together in the forward and after ends, where the frames have no floor-timbers crossing the keel, owing to the form of the ship, there are worked in knee-shaped, horizontal timbers, either with a natural curve, or formed of two or more pieces backed by an iron or wooden knee. These curved supports, secured to either side of the ship, are termed breast-hooks (15) forward and stern-hooks (16) aft; when they support a deck they are called deck-hooks.
The outer planking of a ship is formed of a number of oak planks of varying thickness, but nearly parallel when placed in position over the frames.
To check marine growth on the bottom of vessels and the consequent decrease of speed, all wooden vessels of war are sheathed with copper from the keel to a point some distance above their line of flotation, or “water-line.”
Inner planking. This planking is not continuous, as in the case of outside planking, and in different parts of the ship is called by different names. It is known as the limber-strakes (21) nearest the keelson. These strakes extend along the bottom of the ship on either side of the
|keelson. As the planking is carried up the side beyond the limber-strakes it is known as the ceiling (22); following it up higher we find projecting ledges, called shelf-pieces, or clamps, placed inside the frames to receive the deck-beams.The deck-beams (17), extending from side to side of the ship, holding the sides together, form the support for the deck-planking. The beams are supported by posts or stanchions (23) in their centre, and by clamps at each end. They are joined to the sides of the ship by iron or wooden knees, known as hanging (24), lodging (25), lap (26), or dagger (corruption of diagonal) knees, from their positions and form.The waterways (27) are timbers set in the side over the tops of the deck-beams and bolted to these and to the frames at the side.|
Decks are of oak, teak, or yellow pine, and are spiked to each deck-beam over which they pass.
Vessels owe much of their strength to the use of diagonal trusses or braces, of metal, secured inside of the frame-timbers and forming a net-work which binds the frames firmly together.
