BOWSPRIT, OR BOLT-SPRIT. A large spar, ranking with a lower-mast, projecting over the stem; beyond it extends the jib-boom, and beyond that again the flying jib-boom. To these spars are secured the stays of the fore-mast and of the spars above it; on these stays are set the fore and fore-topmast staysails, the jib, and flying-jib, which have a most useful influence in counter-balancing the pressure of the after-sails, thereby tending to force the ship ahead instead of merely turning her round. In former times underneath these spars were set a sprit-sail, sprit-topsail, &c.
BOWSPRIT, RUNNING. In cutter-rigged vessels. (_See_ CUTTER.)
BOWSPRIT-BITTS. Are strong upright timbers secured to the beams below the deck; they have a cross-piece bolted to them, the inner end of the bowsprit steps between them, and is thus prevented from slipping in. The cross-piece prevents it from canting up.
BOWSPRIT-CAP. The crance or cap on the outer end of the bowsprit, through which the jib-boom traverses.
BOWSPRIT-GEAR. A term denoting the ropes, blocks, &c., belonging to the bowsprit.
BOWSPRIT-HEART. The heart or block of wood used to secure the lower end of the fore-stay, through which the inner end of the jib-boom is inserted. It is seldom, if ever, used now, an iron band round the bowsprit, with an eye on each side for the fore-stays, being preferred.
BOWSPRIT-HORSES. The ridge-ropes which extend from the bowsprit-cap to the knight-heads.
BOWSPRIT-LADDER. Skids over the bowsprit from the beak-head in some ships, to enable men to run out upon the bowsprit.
BOWSPRIT-NETTING. The netting placed just above a vessel's bowsprit, for stowing away the fore-topmast staysail; it is usually lashed between the ridge-ropes.
BOWSPRIT-SHROUDS. Strong ropes or chains leading from nearly the outer end of the bowsprit to the luff of the bow, giving lateral support to that spar.
BOW-STAVES. Early supplied to our men-of-war.
BOW-TIMBERS. Those which form the bow of the ship.
BOX. The space between the back-board and the stern-post of a boat, where the coxswain sits.
BOXES OF THE PUMPS. Each ordinary pump has an upper and lower box, the one a fixture in the lower part of its chamber, the other attached to the end of the spear or piston-rod; in the centre of each box is a valve opening upwards.
