Maybe not the most modern roller furling system, but it ALWAYS worked. I like that it is open and does not leave any space for the roller furling line to get stuck. I could even cut it though with a good knife. Built-in options in the Schaefer System 1100 allows for performance sailing, racing or cruising. Open, split drum makes conversion to full hoist headsails a snap. Round, twin groove extrusions allow for easy sail changes, or carrying dual "wing-on-wing" headsails downwind.
