Abstract
The present invention relates to an arrangement for a driving device for sails on a boat and comprises a worm gear acting between the driving device and a sail furling stay and/or sail furling shaft on the mast. In order, amongst other things, to obtain a compact driving unit, and thus to reduce the space requirements on board the boat in question, the driving device is accommodated internally within a space in the worm gear, inside its worm gear screw, with the driving device arranged coaxially with the screw.
