Four-Sheave Deck Organiser

Keeps four lines separated and turning cleanly across the coachroof with a body low enough not to catch a toe. Each sheave runs on its own bearing so a jammed line does not stall its neighbours.

  • Independent sheaves and bearings, so one line under load does not drag the others.
  • 38 mm overall height keeps the coachroof walkable in bare feet.
  • Countersunk 4-bolt base with a sealing groove for the bedding compound.
  • Available in two, three, four and five sheave configurations on a common base pitch.

Product Details

The standard turning point when halyards are led aft. Mount it far enough forward that the lead angle into the clutch stays under about 8 degrees, otherwise the line rides the sheave flange and the cover wears quickly.

The base is designed for a bolted, bedded fixing into a reinforced deck. We do not recommend self-tapping screws at this load, regardless of what the previous installation used.
