>for the sailors it feels like there is no wind, but the sails are carrying massive pressure The only way this is possible is if the sails are moving at a different airspeed than the sailors, which is only possible if 1) the sailor is running up and down the deck or 2) there is an windspeed gradient with altitude, which the sails penetrate by virtue of being tall. |
