he watch by constantly calling it unnecessarily to trim,
make, or shorten sail.

JIBBER THE KIBBER. A cant term for a diabolical trick for decoying
vessels on shore for plunder, by tying a lantern to a horse's neck, one
of whose legs is checked; so that at night the motion has somewhat the
appearance of a ship's light.--_Jib_ or _jibber_ means a horse that
starts or shrinks; and Shakspeare uses it in the sense of a worn-out
horse.

JIB-BOOM. A continuation of the bowsprit forward, being a spar run out
from the extremity in a similar manner to a top-mast on a lower-mast,
and serving to extend the foot of the jib and the stay of the
foretop-gallant-mast, the tack of the jib being lashed to it. It is
usually attached to the bowsprit by means of the cap and the saddle,
where a strong lashing confines it.--_Flying jib-boom._ A boom extended
beyond the preceding, to which it is secured by a boom-iron and
heel-lashing; to the outer end of this boom the tack of the flying-jib
is hauled out, and the fore-royal-stay passes through it.

JIB-FORESAIL. In cutters, schooners, &c., it is the stay-foresail.

JIB-GUYS. Stout ropes which act as backstays do to a mast, by supporting
the jib-boom against the pressure of its sail and the ship's motion.

JIBING, OR GYBING. A corruption of _jibbing_. The act of shifting over
the boom of a fore-and-aft sail from one side of the vessel to the
other. By a boom-sail is meant any sail the bottom of which is extended
by a boom, which has its fore-end jawed or hooked to its respective
mast, so as to swing occasionally on either side of the vessel,
describing an arc, of which the mast will be the centre. As the wind or
the course changes, the boom and its sail are jibed to the other side of
the vessel, as a door turns on its hinges.

JIB OF JIBS. A sixth jib on the bowsprit, only known to flying-kite-men:
the sequence being--storm, inner, outer, flying, spindle, jib of jibs.

JIB-STAY. The stay on which the jib is set.

JIB-TOPSAIL. A light sail set on the topmost stay of a fore-and-aft
rigged vessel.

JIB-TRAVELLER. An iron ring fitted to run out and in on the jib-boom,
for the purpose of bringing outwards or inwards the tack, or the outer
corner of the sail; to this traveller the jib-guys are lashed.

JIB-TYE. A rope rove through a sheave or block on the fore-topmast head,
for hoisting the jib.

JIFFY. A short space of time, a moment. "In a jiffy," in an instant;
equivalent with crack,
