points
of sail
The angle between
a sailboat's directions and the true wind is referred to as points of
sailing. The points of sailing are divided into three main categories:
running, reaching and sailing upwind.
Running - sailing with the wind blowing from behind. The true angle of
wind matches the heading of the boat.
Reaching - is sailing with the wind blowing across the boat. On a broad
reach the wind blows at an angle of 45 degrees over the transom.
Upwind - is sailing
towards the wind. The goal is to point the boat as high as possible towards
the wind, at approximately 30 degrees away from true wind
