It is the … WebMay 14, 2024 · Wind Angles. Knowing the optimal wind angle for your boat is the first step to choosing the right downwind sail type. Wind angle is the single most important factor in downwind sail design, but the terminology can be confusing. Many sailors think in terms of True Wind Speed (TWS) and True Wind Angle (TWA).

At this speed relative to wind speed the apparent wind angle closes down rapidly and TWA is limited. An old 12m went much slower relative to wind speed hence could probably manage tighter TWA values for similar AWA values.

"WebDec 1, 2015 · "Beam reach is when the apparent wind is 90-degrees (sideways) to the boat. Because of the way boat speed and true wind interact, you've got to go downwind 130 degrees to the true wind (40 degrees past perpendicular) to get to a beam reach." All the diagrams I've seen define beam reach as 90 degrees to the true wind, not the apparent … " - True wind angle

WebJun 24, 2024 · But both "apparent wind" and "true wind" normally mean angles relative to the boat - 42º to stbd, for instance, or 120º to port. With traditional separate instruments you get apparent wind from the wind unit alone, and then if you feed it a speed-through-water from the log you will also get true wind.

WebApparent vs. True: Once we have the measures for Apparent, our software (the SailTimer API) can convert to True wind speed, wind direction and wind angle by accounting for the boat's movement. Apparent is what the wind cups and arrow measure. But when you are sailing along, the boat's movement will cause air flow (the same as if you put your ... WebIf you are using a wind meter you can estimate the true wind speed by sailing close hauled and subtracting 80% of the boat speed from the apparent wind reading of the wind meter. That will get you very close. For example, if the apparent wind is 20 knots and the boat is going 6.2 knots at 45 degrees to the true wind then the true wind is 20 - 6 ...

The recognized points of sail are in reference to the true wind direction, as indicated by a fixed wind indicator (flag, windsock, etc.), and encompass: • Into the wind where a sailing craft is pointed directly upwind in the middle of the no-go zone, where sails cannot generate power. • Close-hauled where a craft is sailing as close to the wind as its sails can generate lift (like a wing) to powe… WebJul 6, 2024 · Good question, one that had me thinking for a second. Actually, the text and the illustration are both right. the text actually says the true wind is 15 degrees more towards the rear of the boat. It’s a matter of the addition of the vectors. If you look at the actual angles, the true wind is coming from behind more than the apparent wind.

WebThe true wind is said to be "Aft" of the apparent wind. This page is an excerpt from the NauticEd FREE Basic SailTrim course.
