FORWARD THERE! The hail to the forecastle.
FOSSE [Ital.] Synonymous with moat or ditch.
FOTHER [Anglo-Saxon foder]. A burden; a weight of lead equal to 191⁄2 cwts. Leaden pigs for ballast.
FOTHERING. Is usually practised to stop a leak at sea. A heavy sail, as the sprit-sail, is closely thrummed with yarn and oakum, and drawn under the bottom: the pressure of the water drives the thrumming into the apertures. If one does not succeed others are added, using all the sails rather than lose the ship.
FOUGADE, or Fougass. A small charged mine, from 6 to 8 feet under a post in danger of falling into the enemy's hands.
FOUL. Generally used in opposition to clear, and implies entangled, embarrassed, or contrary to: as "a ship ran foul of us," that is, entangled herself among our rigging. Also, to contaminate in any way.
FOUL AIR. May be generated by circumstances beyond control: decomposing fungi, timber injected with coal tar, hatches battened down, and ashes or coal washed about. Whole crews on the coast of Africa, and in the West Indies, have been thus swept away, despite every precaution. But generally it may be avoided by cleanliness.
FOUL ANCHOR. An anchor is said to be foul, or fouled, either when it hooks some impediment under water, or when the ship, by the wind shifting, entangles her slack cable a turn round the stock, or round the upper fluke thereof. The last, from its being avoidable by a sharp look-out, is termed the seaman's disgrace.
FOUL BERTH. When a ship anchors in the hawse of another she gives the latter a foul berth; or she may anchor on one tide so near as to swing foul on the change either of wind or tide.
FOUL BILL. See [Bill of Health].
