The internal design creates an 8:1 mechanical advantage for adjusting the depth of the draft of your mains'l, yet eliminates a confusion of line. Mounting the exit block at the extreme aft end of the boom allows enough room for maximum class size sails without crowding. Wires are pre-swaged to the proper length. Line and fasteners are all included.
