Quoins are also employed to wedge off the casks of wine, oil, spirituous liquors, &c. from each other, that their bilges may not rub against each other so as to occasion a leak, by the agitation of the ship, at sea.
R.
RABBIT, rablure, (rabatre, Fr.) a deep groove, or channel, cut in a piece of timber longitudinally, to receive the edge of a plank, or the ends of a number of planks, which are to be securely fastened therein. The depth of this channel is equal to the thickness of the plank, so that when the end of the latter is let into the rabbit, it will be level with the outside of the piece. Thus the ends of the lower planks of a ship’s bottom terminate upon the stem afore, and the stern-post abaft, with whose sides their surfaces are even. The surface of the garboard streak, whose edge is let into the keel, is, in the same manner, level with the side of the keel at the extremities of the vessel.
RACKING, the fastening two opposite parts of a tackle together, so as that any weighty body suspended thereby, shall not fall down, although the rope, which forms the tackle, should be loosened by accident or neglect.
This expedient is chiefly practised when the boats are hung up to the ship’s side, during the night time, in an open road or bay, lest the rope of the tackle should be untied by the inattention of some of the crew; by which accident the boat might be considerably damaged, and probably lost, or dashed in pieces.
RAFT, radeau, a sort of float, formed by an assemblage of various planks, or pieces of timber, fastened together side by side, so as to be conveyed more commodiously, to any short distance in a harbour or road, than if they were separate. The timber and plank, with which merchant-ships are laden, in the different parts of the Baltic sea, are attached together in this manner, in order to float them off to the shipping.
Raft-port, a square hole, cut through the buttocks of some ships, immediately under the counter, to receive the planks or pieces of timber which are brought to lade her for transportation; and which, on account of their great length, could not be received aboard otherwise.
RAG-BOLT, an iron pin, having several barbs, as explained in the article Iron-work, and represented in fig. 2, plate [II].
RAILS, are narrow planks, generally of fir, upon which there is a moulding stuck. They are for ornament, and are nailed across the stern, above the wing-transom and counters, &c. They are likewise nailed upon several planks along the side; one in particular is called the sheer-rail, which limits the height of the side from the forecastle to the quarter-deck, and runs aft to the stern, and forward to the cat-head; the wales are nearly parallel to this. Murray’s Ship-Building.
The reader will understand this article better by referring to the figures of the rails, as represented in plates [I], IV, VII, and VIII. and their explanations, in Naval Architecture, &c.
