Product Overview

The Ronstan Series 40 Deck Organizer is engineered for optimal line management on larger yachts, efficiently deflecting halyards and control lines to winches and cleats. With a robust aluminum and Acetal construction, it ensures durability while minimizing chafing at key tension points.

Technical Specifications

Key Features:

  • Lightweight design with cheek cut-outs for easy bearing maintenance
  • Through-hub mounting for maximum strength and stability
  • All-purpose bearing system for enhanced static load capacity
  • Mounting size with 4 x 6mm (1/4”) fasteners (not supplied)
  • Overall length: 116mm (4 9/16 inches)

Deck organizers effectively deflect halyards and control lines, reducing chafing with alloy cheeks designed for smooth entry and exit of ropes. The system can be stacked for versatile configurations, ensuring the MWL of the top sheaves does not exceed 50% of the total block load rating.

Ideal Applications:

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

Durable Materials:

  • Cheek plates made from anodized aluminum
  • U.V. stabilized Acetal sheaves
  • Grade 316 stainless steel hubs
