The price of liberty is constant vigilance, and the price of a good sail is the same. I have seen a mast snapped off clean at the deck by a jibe, and once when out after ducks every one was so intent upon the game that proper attention was not paid to the sail. The wind got round and brought the boom with a swing aft, knocking the captain of our boat club overboard. Had the boom hit him in the head and stunned him, the result might have been fatal.

Figs. 131½, 132, and 133.—Jibing.

Wing and Wing.—When a schooner goes before the wind with one sail out at nearly right angles on the port side and the other in the same position on the starboard side she is said to be wing and wing and presents a beautiful sight.

Tacking.—Working to the windward by a series of diagonal moves.

Legs.—The moves or diagonal courses made in tacking. It is apparent to the most unthinking observer that no vessel propelled by sail can move against the direct course of the wind—that is, nothing but electricity, naphtha, steam, or some such power can drive a boat into the eye of the wind. But what cannot be accomplished in a direct manner can be done by a series of compromises, each of which will bring us nearer to the desired point.

First we point the boat to the right or left, as the case may be, as near or as close to the wind as the boat will sail. Then we come about and sail in the other direction as close as practicable to the eye of the wind, and each time we gain something in a direct line.

When your boat changes its direction on a tack it is done by "jibing," or "coming about."
