RIBS OF A PARREL. An old species of parrel having alternate ribs and bull's-eyes; the ribs were pieces of wood, each about one foot in length, having two holes in them through which the two parts of the parrel-rope are reeved with a bull's-eye between; the inner smooth edge of the rib rests against, and slides readily up and down, the mast.

RICKERS. Lengths of stout poles cut up for the purpose of stowing flax, hemp, and the like. Spars supplied for boats' masts and yards, boat-hook staves, &c.

RICOCHET. The bound of a shot. Ricochet fire, that whereby, a less charge and a greater elevation being used, the shot or shell is made to just clear a parapet, and bound along the interior of a work.

RIDDLE. A sort of weir in rivers.—To riddle. To fire through and through a vessel, and reduce her to a sieve-like condition.

RIDE, To. To ride at anchor. A vessel rides easily, apeak, athwart, head to wind, out a gale, open hawse, to the tide, to the wind, &c. A rope rides, as when round the capstan or windlass the strain part overlies and jams the preceding turn.—To ride between wind and tide. Said of a ship at anchor when she is acted upon by wind and tide from different directions, and takes up a position which is the result of both forces.

RIDEAU. A rising ground running along a plain, nearly parallel to the works of a place, and therefore prejudicial.

RIDERS. Timbers laid as required, reaching from the keelson to the orlop-beams, to bind a ship and give additional strength. They are variously termed, as lower futtock-riders and middle futtock-riders. When a vessel is weak, or has broken her floors or timbers, riders are introduced to secure the ship, and enable her to reach a port where she can be properly repaired. Stringers are also used, but these run horizontally.—Riders are also upper tiers of casks, or any stowed above the ground tier in the hold.

RIDING A PORT-LAST. With lower yards on the gunwales.

RIDING-BITTS. Those to which the cable is made fast.

RIDING-DOWN. The act of the men who throw their weight on the head of a sail to stretch it. Also, of the man who comes down a stay, &c., to tar it; or foots the bunt in.
