All’s well! an acclamation of safety or security pronounced by a centinel, and repeated by all the others who are stationed in different places of a ship of war, at the time of striking the bell each half-hour during the period of the night watch.

All hands high, or All hands hoay! tout le monde haut! the call or order by which all the ship’s company are summoned upon deck by the boatswain.

ALOFT, en haut, (loffter, to lift up, Dan.) up in the tops, at the mast-heads, or any where about the higher yards or rigging.

ALONG-side, bord à bord, flanc & flanc, side by side, or joined to a ship, wharf, &c. and lying parallel thereto.

To lay Along-side, alonger, to arrange a ship by the side of another.

Along-shore, along the coast; this phrase is commonly applied to coasting-navigation, or to a course which is in sight of, and nearly parallel to, the shore.

Lying Along, à la bande, (au longe, Fr.) the state of being pressed down sideways by a weight of sail in a fresh wind that crosses the ship’s course either directly or obliquely.

ALOOF, lof, this has frequently been mentioned as a sea-term, but whether justly or not we shall not presume to determine; it is known in common discourse to imply, at a distance; and the resemblance of the phrases, keep aloof, and keep a luff, or keep the luff, in all probability gave rise to this conjecture. If it was really a sea-phrase originally, it seems to have referred to the dangers of a lee-shore, in which situation the pilot might naturally apply it in the sense commonly understood, viz. keep all off, or quite off: it is, however, never expressed in that manner by seamen now. See Luff. It may not be improper to observe, that, besides using this phrase in the same sense with us, the French also call the weather side of a ship, and the weather clue of a course, le lof.

AMAIN, cale-tout, (from main, or maigne, old French) at once, suddenly; as, let go amain! i. e. let it run at once. This phrase is generally applied to any thing that is hoisted or lowered by a tackle, or complication of pullies.

AMIDSHIPS, the middle of the ship, either with regard to her length or breadth. Example in the first sense; The enemy boarded us amidships, i. e. in the middle, between the stem and stern. Example in the second sense; Put the helm amidships, i. e. in the middle, between the two sides.
