Deck organizers are an effective means of deflecting halyards and other control lines to winches, stoppers and cleats. Sheaves are made from impact resistant Acetal. The deck organizers have alloy cheeks, flared at rope entry and exit points to minimize chafing. All sizes can be stacked to create double versions - MWL of the top sheaves must not exceed 50% of the total block load rating.


  • Line deflection on larger yachts (depending on load and angle of deflection)
  • Halyard and control line deflection on boats to 11m (36ft)
