UNMOOR.--Pay out on your riding cable, heaving in the slack of the other. When the other is short, trip it, cat and fish, and heave in on your riding cable. Instead of this method, the anchor which you are not riding by may be weighed, if it is a small one, by the long boat. Send the long boat out over the anchor, take aboard the buoy-rope, carrying it over the roller in the boat's stern, or through the end of a davit, clap the watch-tackle to it, and weigh it out of the ground. This done, and the buoy-rope and tackle secured to the boat, heave in on the chain on board, which will bring the anchor alongside, the boat approaching at the same time. When under the bow, cast off the fasts to the boat, heave up the anchor, cat and fish. GETTING UNDER WAY FROM A SINGLE ANCHOR.--It is the duty of the chief mate to see all ready forward for getting under way; the rigging fair for making sail, the cat and fish-tackles rove, and the fish-davit at hand. Heave short on your chain and pawl the windlass. Loose all the sails, if the wind is light, and sheet home and hoist up topsails, topgallant sails, and royals. If there is a stiff breeze, set topsails alone, whole or reefed. You should always, if it will answer, cast on the opposite side from your anchor; that is, if you are riding by your starboard anchor, cast to port. Brace your head yards aback and your after yards full, for the tack you mean to cast upon. The sails being set, man the windlass again, give her a sheer with the helm, and trip your anchor. The mate reports when it is away. As soon as it is away, hoist the jib. The fore topsail aback will pay her head off. Put the helm for stern-board. When her head is off enough, fill away the head yards and haul out the spanker, shifting the helm for headway. Trim the yards for your course, and make sail on her. If the wind is light and the sea smooth, you may cat and fish your anchor after you get under way; but it is best in a rough sea to keep the vessel hove-to until the anchor is catted and fished.
