how wind is important for sailing a boat?
Answers
Answer:
because of the cloth on the boat it gives force to the boat because of the wind
Answer:
Explanation:
Many larger sailboats, especially those that race or cruise long distances have electronic wind instruments, which are coming down in price but still tend to be expensive. Sensors at the masthead measure wind speed and direction reported on gauges or readouts typically in the cockpit where the helmsperson can easily see them. These precise measurements help sailors determine the best strategies not only for sail trim but also for routing and strategic planning. Changes are easily noticed, allowing for sail changes, reefing, etc. at an appropriate time.
The latest trends in electronic wind instrumentation are wireless sensors (to avoid having to route more wires through the mast) and integration of wind information with other data on a single display such as a plotter or computer screen. Sophisticated routing software integrates wind data in course planning.
The average recreational sailor, however, does not need expensive or sophisticated wind instruments to sail well. Wind direction is not difficult to determine, and with a little experience, one can estimate wind speed fairly accurately. A sailor wanting more precise wind speed data can use an inexpensive handheld wind-meter.
After electronics, the best wind direction indicator is a wind vane or masthead fly, such as the Windex. Like an old-fashioned rooftop weather vane, the masthead fly is essentially an arrow pointing into the direction from which the wind is coming (remember this is apparent wind, affected by the boat's direction of motion and speed, not true wind direction). Most masthead flies also have two backswept arms that help the sailor determine how close the boat can come to the wind when close-hauled.
Finally, small sailboats and even medium-sized or larger ones without a masthead fly may simply have telltales on the shrouds to help one judge wind direction. Commercial telltales are available but usually work no better than short lengths of light yarn tied to the shrouds on both sides. Remember to observe the telltales on the windward side, not those on the leeward side which are more affected by the sails.
