Re: another (easy to answer) roller furler question
It probably has to go the other way because the UV cover was sewn onto the other side of the sail. If you wind it up backwards bare sail cloth will be exposed, and the sail will get UV damaged much more quickly.
To change the furling line direction you need to drop the sail, unroll the furling line the whole way, and wrap it in the other way before installing the other sail.
It's odd that he had two sails made with the UV cover on opposite sides.
