| 11. | Although the boat is sailing perpendicular to the true wind, its sails are set for close hauled sailing.
|
| 12. | Note that the true wind is added using vector addition to the head wind created by the boat's speed.
|
| 13. | Figure 1 shows the relationship of the true wind and apparent wind vectors as differing by the yacht velocity.
|
| 14. | Bryant recommended further removal of the point which would allow a true wind along the whole channel past the dangerous sandbar.
|
| 15. | It can sail slightly faster, as a multiple of the windspeed, if it sails at a greater angle off the true wind.
|
| 16. | She then sailed for 40 minutes on a south-south-east course with true wind speeds of about, attaining a top recorded speed of.
|
| 17. | These devices can be calibrated to measure the true wind speed and the apparent wind speed ( speed that a sailor would'feel').
|
| 18. | The boat will accelerate, so the apparent wind will be less than the true wind and will shift forward of the true wind.
|
| 19. | The boat will accelerate, so the apparent wind will be less than the true wind and will shift forward of the true wind.
|
| 20. | "Apparent wind " velocity is the vector sum of the " true wind " and the headwind an object would experience in still air.
