FLOATING ANCHOR. A simple machine consisting of a fourfold canvas, stretched by two cross-bars of iron, rivetted in the centre, and swifted at the ends. It is made to hang perpendicularly at some distance below the surface, where it presents great resistance to being dragged through the water, diminishing a ship's leeward drift in a gale where there is no anchorage.[307]

FLOATING BATTERY. A vessel expressly fitted for action in harbours or sheltered waters, having heavier offensive and defensive dispositions (generally including much iron-plating) than would be compatible with a sea-going character. Also, a vessel used as a battery to cover troops landing on an enemy's coast. Also, one expressly fitted for harbour defence.

FLOATING BETHEL. An old ship fitted up in a commercial port for the purpose of public Worship.

FLOATING BRIDGE. A passage formed across a river or creek by means of bridges of boats, as over the Douro, Rhine, &c.

FLOATING PIER. As the stage at Liverpool.

FLOATING STAGE. For caulkers, painters, &c.

FLOATS. Large flat-bottomed boats, for carrying blocks of stone. Also, the 'thwart boards forming the circumference and force of the paddle-wheels of steamers.

FLOE. A field of floating ice of any extent, as beyond the range of vision, for notwithstanding its cracks the floes pressed together are assumed as one; hence, if ships make fast to the floe-edge, and it parts from the main body, sail is made, and the ship goes to the next available floe-edge.

FLOGGING THE GLASS. Where there is no ship time-piece the watches and half-hour bells are governed by a half-hour sand-glass. The run of the sand was supposed to be quickened by vibration, hence some weary soul towards the end of his watch was said to flog the glass.

FLOME. An old word for a river or flood.

FLOOD AND FLOOD-TIDE. The flux of the tide, or the time the water continues rising. When the water begins to rise, it is called a young flood, next it is quarter-flood, half-flood, and top of flood, or high water.

FLOOD-ANCHOR. That which the ship rides by during the flood-tide.

FLOOD-MARK. The line made by the tide upon the shore at its greatest height; it is also called high-water mark. This denotes the jurisdiction of the High Court of Admiralty, or vice-admirals of counties.

FLOOK, or Fluck. The flounder; but the name, which is of very old standing, is also applied to various other pleuronects or flat-fish.

FLOOR. The bottom of a vessel on each side of the kelson; but strictly taken, it is only so much of her bottom as she rests upon when aground. Such ships as have long and withal broad floors, lie on the ground with most security; whereas others which are narrow in the floor, fall over on their sides and break their timbers.[308]

FLOOR-GUIDE. In ship-building, is a ribband placed between the floor and the keel.

FLOOR-HEAD. This, in marine architecture, is the third diagonal, terminating the length of the floors near the bilge of the ship, and bevellings are taken from it both forward and abaft. The upper extremities of a vessel's floor-timbers, plumb to the quarter-beam.

FLOOR-HOLLOW. The inflected curve of the floor, extending from the keel to the back of the floor-sweep, which the floor does not take.

FLOOR-PLANS. In naval architecture, are longitudinal sections, whereon are represented the water-lines and ribband-lines.

FLOOR-RIBBAND. This is an important fir-timber which runs round a little below the floor-heads, for the support of the floors.

FLOOR-RIDERS. Knees brought in from side to side over the floor ceiling and kelson, to support the bottom, if bilged or weak, for heavy cargo.

FLOORS, or Floor-timbers. Those parts of the ship's timbers which are placed immediately across the keel, and upon which the bottom of the ship is framed; to these the upper parts of the timbers are united, being only a continuation of floor-timbers upwards.

FLOOR-SWEEPS. The radii that sweep the heads of the floors. The first in the builder's draught, which is limited by a line in the body-plan, perpendicular to the plane of elevation, a little above the keel; and the height of this line above the keel is called the dead-rising.

FLOP, To. To fall flat down: as "soused flop in the lee-scuppers."

FLORY-BOATS. A local term for boats employed in carrying passengers to and fro from steamers which cannot get alongside of a quay at low-water.

FLOTSAM. In legal phraseology, is the place where shipwrecked goods continue to float and become derelict property. Sometimes spelled flotson.

FLOUNDER. A well-known pleuronect, better to fish for than to eat. Called also floun-dab.

FLOW. In tidology, the rising of the tide; the opposite of ebb. Also, the course or direction of running waters.[309]

FLOWER of the Winds. The mariner's compass on maps and charts.

FLOWERING. The phenomenon observed usually in connection with the spawning of fish, at the distance of four leagues from shore. The water appears to be saturated with a thick jelly, filled with the ova of fish, which is known by its adhering to the ropes that the cobles anchor with while fishing, for they find the first six or seven fathom of rope free from spawn, the next ten or twelve covered with slimy matter, and the remainder again free to the bottom; this gelatinous material may supply the new-born fry with food, and protect them by clouding the water.

FLOWING-HOPE. See Forlorn Hope.

FLOWING-SHEET. In sailing free or large, is the position of the sheets or lower clues of the principal sails when they are eased off to the wind, so as to receive it more nearly perpendicular than when they are close-hauled, although more obliquely than when going before the wind; a ship is therefore said to have a flowing-sheet, when the wind crosses the line of her course nearly at right angles; that is to say, a ship steering due north with the wind at east, or directly on her side, will have a flowing-sheet; whereas, if the sheets were hauled close aft, she would sail two points nearer the wind—viz. N. N. E.

This explanation will probably be better understood by considering the yards as plane faces of wedges—the more oblique fore and aft, the less head-way force is given, until 22° before the transverse line or beam. This is the swiftest line of sailing. As the wind draws aft of the beam the speed decreases (unless the wind increases), so that a vessel with the wind abeam, and every sail drawing, goes much faster than she would with the same wind before it.

FLUCTUATION of the Tide. The rising and falling of the waters.

FLUE. See Flukes.

FLUES. In a steamer's boiler, are a series of oblong passages from the furnaces for the issue of heated air. Their object being, that the air, before escaping, shall impart some of its heat to the water in the boiler, thereby economizing fuel.

FLUFFIT. The movement of fishes' fins.

FLUID COMPASS. That in which the card revolves in its bowl floated by alcohol, which prevents the needle from undue vibrations. The pin is downwards to prevent rising, as in the suspended compass-card. The body, or card, on which the points of the compass are marked, is constructed of two segments of a globe, having a diameter of 7 inches to the (double) depth of 1 inch at the poles.

FLUKES. The two parts which constitute the large triangular tail of the whale; from the power of these the phrase obtained among whalers of fluking or all-a-fluking, when running with a fresh free wind. Flukes, or palms, are also the broad triangular plates of iron on each arm of the anchor, inside the bills or extreme points, which having entered the ground, hold the ship. Seamen, by custom, drop the k, and pronounce the word flue.

FLUMMERY. A dish made of oatmeal, or oats soured, [310]&c.

FLURRY. The convulsive movements of a dying whale. Also, a light breeze of wind shifting to different points, and causing a little ruffling on the sea. Also, hurry and confusion.

FLUVIAL LAGOONS. Contradistinguished from marine lagoons, in being formed by river deposits.

FLUX. The flowing in of the tide.

FLY of a Flag. The breadth from the staff to the extreme end that flutters loose in the wind. If an ensign, the part which extends from the union to the outer part; the vertical height, to the head-toggle of which the halliards are bent, or which is next to the staff, is called the hoist; the lower (which is a rope rove through the canvas heading, and into which the head-toggle is spliced) is the long tack; on this rope the whole strain is sustained.

FLY, or Compass-card, placed on the magnetic-needle and supported by a pin, whereon it turns freely. (See Compass.)

FLY-AWAY. Fictitious resemblance of land; "Dutchman's cape," &c. (See Cape Fly-away.)

FLY-BLOCK. The block spliced into the topsail-tye; it is large and flat, and sometimes double.

FLYING DUTCHMAN. A famous marine spectre ship, formerly supposed to haunt the Cape of Good Hope. The tradition of seamen was[311] that a Dutch skipper, irritated with a foul wind, swore by donner and blitzen, that he would beat into Table Bay in spite of God or man, and that, foundering with the wicked oath on his lips, he has ever since been working off and on near the Cape. The term is now extended to false reports of vessels seen.

FLYING JIB. A light sail set before the jib, on the flying jib-boom. The third jib in large ships, as the inner jib, the jib, and the flying jib, set on the flying jib-boom. (See Jib.)

FLYING JIB-BOOM. A spar which is pointed through the iron at the jib-boom end. It lies beside it, and the heel steps into the bowsprit cap.
