From Wikipedia ![]() But if you pedal 10 mph due south, you will feel anapparentwindof 5 mph from the south. From Wikipedia ![]() If you pedal at 10 mph due north, you will feel anapparentwindof 15 mph from the north. From Wikipedia ![]() If the ship moves upwind, the two winds are cumulative, and theapparentwindis larger than the actual wind. From Wikipedia ![]() The shape of the sail is approximated by a plane perpendicular to theapparentwind. From Wikipedia ![]() Theapparentwindis at an acutely aft angle to the axis of the ship. From Wikipedia ![]() At each speed increaseapparentwinddirection moves. From Wikipedia ![]() This is consistent with the yacht being able to sail at about 15 degrees off theapparentwind, see the table above. From Wikipedia ![]() Figure 1 shows the relationship of the true wind andapparentwindvectors as differing by the yacht velocity. From Wikipedia ![]() The effect of this is to radically change theapparentwinddirection when sailing downwind. From Wikipedia ![]() Theapparentwindis not constant for two reasons: wind and sea.

From Wikipedia ![]() The more the boat accelerates the more theapparentwindincreases. From Wikipedia ![]() Setting smaller sails moderates thisapparentwindeffect.

From Wikipedia ![]() The polar plot is independent of theapparentwindspeed. From Wikipedia ![]() The more the boat approaches the true wind speed the lower theapparentwindpushing the sail. From Wikipedia ![]() Iceboats can sail even closer to theapparentwind. From Wikipedia ![]() Alpha is the angle of the sails to theapparentwind.
