Re: Using Jib and Genoa at the same time to create spinnaker
Boats set up for flying twin jibs often have double forestays so each jib is hoisted on its own forestay. That way the hanks don't interfere with each other. A double-slotted roller-furler setup could work the same way. You obviously need two halyards to do this, and any roller-furler snafus would be twice as bad as they might have been otherwise. Most often people seem to fly two jibs of the same size - as in the photo above . This helps to keep the forces even and make it easier to steer a straight course.
