rection, use stationary flags. If a boat is moving, the
speed of the boat affects the way its
onboard flags are flying.
Wind Awareness When preparing to sail, you need to know the wind direction. Look around. You might see a flag waving from a pole, or the telltale, a piece of yarn tied to the shroud, streaming in the breeze. Position your boat so the bow points into the wind.
Wind Detection Te speed and direction of the wind are variable. Increases in wind velocity are known as puffs, while decreases are lulls. Wind direction can shiſt dramatically over hours or just slightly every few minutes. With practice, you will learn to “see” changes in the wind’s strength.
direction and
Wind Direction Indicators 1. Telltales on the shrouds of your boat.
2. Ripples on the water. Te wind creates rows of wavelets at right angles to its direction. Calm glassy areas with few ripples characterize lulls, and darker ripples show areas of puffs.
3. Feel the wind on your face, neck or hands.
4. Notice how boats at anchor usually face into the wind, unless they also have current pushing them.
5. Look on shore for flags that are fluttering (luffing) in the wind and smokestacks.
