The Sailor's Word-Book Part 242

THREE HALF-HITCHES ARE MORE THAN A KING'S YACHT WANTS. An exclamatory remark to a green hand, meaning that two are enough.

THREE SHEETS IN THE WIND. Unsteady from drink.

THREE SISTERS. Formerly the badge of office of boatswains' mates and masters-at-arms, made of three rattans bound together with waxed twine.

THREE-SQUARE. An odd word applied to staysails, or anything triangular, as was the oblong square to a parallelogram.

THRIFT. _Armeria_, a genus of handsome plants growing on the sea-coast.

THROAT. The widened and hollowed end of a gaff next the mast; opposed to _peak_, the outer end. Also, the midship portion of the floor-timbers and transoms. The contrary of _breech_.

THROAT-BOLTS. Eye-bolts fixed in the lower part of tops, and the jaw-ends of gaffs, for hooking the throat-halliards to.

THROAT-BRAILS. Those which are attached to the gaff for trussing up the sail close to the gaff as well as the mast. (_See_ BRAILS, and TOPMAST-STAYSAILS.) Falconer says:--

"For he who strives the tempest to disarm, Will never first embrail the lee yard-arm."

Brail thus applies to leech-lines, clue-lines, &c.

THROAT-HALLIARDS. Ropes or tackles applied to hoist the inner part of the gaff, and its portion of the sail, and hook on to the throat-bolts, as above.

THROAT-SEIZING. In blocks, confines the hook and thimble in the strop home to the scores. Also, in turning in rigging, the throat-seizing is pa.s.sed with riding turns, through which the end is hove taut, and being turned up sharply, is well seized to the standing part of the rigging, making it a severe cross nip, which cannot render or slip.

THROT. That part of the mizen-yard close to the mast.

THROTTLE-VALVE. A valve in the steam-pipe of an engine for preventing the escape of steam, or regulating the velocity of its pa.s.sage from the boiler to the cylinder.

THROUGH ALL. Carrying canvas in heavy squalls without starting a st.i.tch.

It demands not only courage, but seamanlike judgment. Also applied to the cable, or any purchase where, by reason of its slipperiness, the purchase does not nip; she is then said to be "heaving through all."

"Fresh nippers, thick and dry, for weighing," are then called for, and sand applied to overcome the slipping.

THROUGH FASTENINGS. Applied to bolts and tree-nails driven through both the timber and plank of the sides.

THROUGH-PIECES. _See_ GRAVING-PIECES.

THROUGH THE FLEET. A seaman's being sentenced by court-martial to be towed by a boat from every ship through the fleet, and receive alongside each a proportion of the lashes to be inflicted. But this was only awarded where the offence deserved a less punishment than death, and is now discontinued, solitary confinement or penal servitude being subst.i.tuted.

THROW. A cast of the hand-lead.

THROWING A STEAM-ENGINE OUT OF GEAR. Disconnecting the eccentric rod from the gab-lever.

THRUM. Any coa.r.s.e woollen or hempen yarn. It is used for mops, &c., in the cabins; also for mats, which are worked on canvas with a large bolt-rope needle.--_To thrum._ A vessel, when leaky, is thrummed by working some heavy spare sail, as the sprit-sail, into a thrummed mat, greasing and tarring it well, pa.s.sing it under the bottom, and heaving all parts tight. The pressure forces the tarred oak.u.m into the openings, and thus, in part, arrests the ingress of water.

THRUMMED MAT. A small mat faced with rope-yarn or spun yarn, which is used in a vessel's rigging to prevent chafing.

THRUST. The effort of a screw-propeller.

THUD. The sound of a bullet on hitting the intended object.

THULE [Gaelic _thuath_]. An extreme object to the north.

THUMB-CLEAT. In shape resembling a thumb. They arrest the topsail-reef-earings from slipping, and are also lashed to the rigging with a hollow, cut out to act as a hook, to suspend the bight of a rope, as the truss-pendants on the lower masts.

THUNDERING. A sailor's emphatic word for anything choice, large, fine, or powerful.

THUNDER SQUALL. This is similar to the black squall, only that it is always preceded and attended by lightning and thunder, and accompanied by extremely heavy rain.

THUNNY. _See_ TUNNY.

THUS, VERY WELL THUS, OR DYCE. The order to the helmsman to keep the ship in her present direction, when sailing close-hauled. This truly sailor's motto was adopted by the Earl St. Vincent.

THWART CLAMPS OR KNEES. Those which secure the after, main, and fore thwarts to the rising and gunwales, and which support the masts.

THWART-MARKS, TO A HARBOUR. Two objects on the land, which, brought into line with each other, mark the safe course between shoals, as those on Southsea Common act for the Needles, Swashways, &c.

THWARTS (properly ATHWARTS). The seats or benches athwart a boat whereon the rowers sit to manage their oars.

THWART-SHIPS. Across the ship, or from one side to the other. (_See_ ATHWART.)

TIBRIC. An old name for the coal-fish.

TIBURON [Sp.] The shark.

TICKET. An official warrant of discharge, so that a heavy penalty attaches to the loss of any of the blank ones in the captain's charge.

It is always used in counterparts, which are ordered to be perfect duplicates of each other.

TICKET-BOOK. A register for accounting for all tickets and certificates received and used.

TICKLING OF FISH. The same as _gennelin_. (_See_ GROPING.)

TIDAL WAVE. The wave caused by the combined action of the sun and moon: its greatest influence is felt some time after the moon has pa.s.sed the meridian of any place.

TIDE. A regular periodical current of waters, setting alternately in a flux and reflux; it is owing to the attraction of the sun and moon, but chiefly to the latter. The highest as well as most rapid, perhaps, are in the Gulf of Fundy and the river Wye; and on the contrary the lowest, as well as feeblest, are in the Mediterranean generally.--_To tide_, is to work up or down a river or harbour, with a fair tide in a head wind or a calm; coming to anchor when the tide turns.

TIDE OR TIDAL HARBOUR. A port which can only be entered at a certain time of flood.

TIDE AND HALF-TIDE. Those roadsteads affected by several rivers or channels leading into them; as, for instance, Spithead.

TIDE-BALL. A ball hoisted to denote when the depth of water permits vessels to enter a bar-harbour, or to take the bar outside, from the known depth within.

TIDE-GATE. A place where the tide runs strong.

TIDE-GAUGE. An instrument contrived for measuring the height of the tides.

TIDE, EBB OF. The falling tide.

TIDE-POOL. A sort of basin worn in seaside rocks.
