Karver Anti-Twist Halyard Swivel 4.5T: A Versatile Solution for Code Zero and Mainsail 2:1 Halyard Systems

The Karver Anti-Twist Halyard Swivel 4.5T is designed to address the common issue of halyard twist in 2:1 halyard setups, whether for Code Zero sails or mainsails. In this configuration, the halyard is dead-ended at the masthead, passes through a block on the top of the sail, and returns to the masthead sheave. This looped system often leads to twisting, increasing friction, reducing efficiency, and risking wear on the halyard.

Key Features:

• Eliminates Halyard Twist: The swivel allows the halyard loop to rotate freely, preventing the accumulation of tension and twist that can impact sail performance and cause damage.
• High Load Capacity: Engineered for working loads up to 3 tons, it meets the demands of high-tension applications, including large Code Zero sails and mainsails on larger yachts.
• Advanced Bearing System: Equipped with low-friction, high-load bearings, ensuring smooth, efficient rotation even under heavy loads and demanding conditions.
• Flexible Integration: Supplied with eye-eye fittings as standard, with optional fork-fork fittings available upon request, making it compatible with various rigging setups.
• Durable and Reliable: Constructed with robust materials to withstand harsh marine environments, providing long-lasting performance and dependability.

Applications:

• Code Zero Halyards: Prevents twist in 2:1 halyard setups, ensuring smoother furling and reduced wear.
• Mainsail Halyards: Optimizes performance and reduces friction, especially in high-load configurations, for more efficient sail handling.

The Karver Anti-Twist Halyard Swivel 4.5T is a versatile and essential addition for both Code Zero and mainsail 2:1 halyard systems. By incorporating this swivel, sailors can achieve smoother sail handling, enhanced performance, and longer equipment life, ensuring a more reliable and efficient rigging system.
