Unfurling a main sail is easy.
Release vang and topping lift
tension. Bring the boat to beam reach on the side opposite to the furling direction. (helps pull the sail from inside the groove)
For furling in, apply tension to the outhaul
and go slightly upwind keeping in mind the direction of the furl.. and bring in the sail. Keep the tension until fully furled.. not too tight.
Ensure all components are cleaned and well lubricated... works very well.
Changing to hanked on will cost you for the hardware
and a new sail!!!
If you are not already in the buy phase, look at Hanse... most have hanked on mains with battens.
