Before re-hoisting the bowman doesn't need to remove the headsail from the luff grove, he just has to open the prefeeder and close it around the luff tape. To open, simply push the spring with your thumb, the jaws will open automatically. To close, squeeze the jaws together between thumb and fingers, until the spring reengages.
The prefeeder can be easily installed below any headsail foil or headsail reefing configuration. In the closed position, it ensures a smooth and easy sail hoist.
