Schafer Roller Furling adjustment?
The Schaefer RF foil and drum sections go over a regular normal wire forestay. Normally, there would be a turnbuckle at the bottom of the forestay that connects to a tang on the lower end. To access the turnbuckle, it is necessary to loosen a set screw to allow the drum to slide up on the foil. Refer to the Schaefer manual for location of the set screw. Good luck.
