Beam

9

Beam reach (90 degrees to the apparent wind, sailing with the wind on the beam. Point of sail when the apparent wind comes from directly abeam). Sailing on a point of sail such that the apparent wind is coming from the beam side of the boat at about a 90 degree angle. A beam reach is usually the fastest point of sail. A beam reach is a point of sail between a broad reach and a close reach.

Broad on the beam In the direction of one of the sides of the vessel. Abeam. The position of an object that lies off to one side of the vessel. Broad on: In the general direction of. Ex: broad on the port bow describes the general direction forward of the beam on the port side.

17

Broad reach (22.5 degrees away from directly downwind sailing). A point of sailing in which the wind is within a few points of the beam, either forward of the beam (close reach), directly abeam (beam reach), or abaft of the beam (broad reach). A point of sail when the wind comes from either quarter. Broadside to the sea

Black diamond, ball, and cone shapes hoisted on vessels during the day to indicate restricted movement ability or type. For example three balls means aground.
