The technical challenge of rolling and trimming sails

Admittedly, the mechanisms for rolling the sails in strong winds and storms and for adjusting the sails in moderate winds are not simple. But the problems are solved technically. We will hide servomotors under the gondola roof, so that the technology of SAILWIND is not visible. Almost a pity, but otherwise the charm of a traditional sail windmill would be lost. The picture above is just a scetch from SAILWIND 4.
