The Ensign jib halyard fine tune adjustment system is very unique and effective. The key to the ease of adjustment is the 8:1 magic box. As Harken stopped making in early 2000, we are fortunate to offer the RWO 8:1 magic box.

The line from the box is cleated to a H338 small cam cleat. The other end has a 3/16” AmSteel strop running from the clevis pin on the box, through a 40mm Harken carbo block (which is shackled to a second of the same block) and spliced to a welded pad eye (SC7803).

The halyard leads through a 40mm carbo cheek (2644) block mounted on the side of the mast just off of the deck. It the runs through the second of the united singles, back through another cheek (mounted on the deck to port) and back to a large cam cleat (H150). Once the halyard is hoisted and cleated off you can play the line off of the magic box to fine tune halyard tension.
