1. The ship and her sea room. 2. The track of the cyclone. 3. Its rate of traveling. 4. The ship’s run and drift. While, on the part of the commander, caution and watchfulness are essentially requisite, still all the circumstances being favorable, rules may be given in a very brief compass for trimming a vessel to the hurricane winds. These are embodied in the following tables. Where the directions of the wind vane, as set down in the first column are tangents to the whirlwind in its course, these indicate the quarter from which the storm sets in. The points of the compass in the second column show the position of the storm’s center as regards the vessel. The fourth column gives the direction in which to steer when the wind shifts as indicated in the third column; but if it shifts as indicated in the fifth column, then bear away as told in the sixth column.
