A SQUALL.--If you see a squall approaching, take in the light sails, stand by to clew down, and keep her off a little, if necessary. If you are taken by one, unprepared, with all sail set and close-hauled, put the helm hard up, let go the spanker sheet and outhaul, and the main sheet. Clew up royals and topgallant sails, haul down flying-jib, haul up the mainsail, and clew down the mizzen topsail. When you are before the wind, clew down the topsail yards, and haul out the reef-tackles. You may run before the squall until it moderates, or furl the light sails, bring by the wind, and reef. A MAN OVERBOARD.[5]--The moment the cry is heard, put the helm down and bring her up into the wind, whether she is on the wind or free, and deaden her headway. Throw overboard instantly life buoys, or, if there are none at hand, take a grating, the carpenter's bench, or any pieces of plank or loose spars there may be about decks; and let two or three hands clear away a quarter boat. The best plan is, if the vessel was on the wind, to haul the mainsail up and brace aback the after yards and raise the head sheets; then, having her main yard aback, she will drift down directly toward the man. Keep your head sails full to steady her, while the after ones stop her headway. [5] See Totten's Naval Text Book, Letter XX. If you are sailing free, with studdingsails set, clew up the lower studdingsail, brace up the head yards, haul forward the fore tack, and keep the head yards full, while you luff up to back the after ones. Lower away the boat as soon as it is safe, and, as the vessel will have turned nearly round, direct the boat with reference to her position when the accident happened and her progress since. COLLISION.--If two vessels approach one another, both having a free wind, each keeps to the right. That is, the one with her starboard tacks aboard keeps on or luffs; and the other, if it is necessary to alter her course, keeps off. So, if two vessels approach one another close-hauled on different tacks, and it is doubtful which is to windward, the vessel on the starboard tack keeps on her course, and the other gives way and keeps off. That is, each goes to the right, and the vessel with her starboard tacks aboard has the preference. The only exception to this is, that if the vessel on the larboard tack is so much to windward that in case both persist the vessel on the starboard tack will strike her to leeward and abaft the beam; then the vessel on the starboard tack must give way, as she can do it more easily than the other. Another rule is that if one vessel is going dead before the wind and the other going free on the starboard tack, the latter must luff and go under the stern of the former. CHAPTER XIV.
