The XXC0812 is an ultra-high-performance clutch designed to meet the growing demand for secure handling of high loads. It offers a 30% higher working load capacity compared to the standard XX0812 while maintaining controlled release under load. This model delivers a 50% increase in power-to-weight ratio and is 15% lighter than its predecessor. It is optimized for high-performance line diameters ranging from 8mm to 12mm. The unit features advanced materials and design for durability and ease of maintenance on deck.
Performance and Load Capacity
Working Load: Holds up to 2350kg, providing a 30% higher capacity than the standard XX0812 model.
Controlled Release: Maintains controlled release capabilities even under maximum load conditions.
Power-to-Weight: Delivers a 50% increase in power-to-weight ratio while being 15% lighter.
Line Compatibility: Optimized for high-performance line diameters between 8mm and 12mm (5/16" to 1/2").
Jaw Technology: Ceramic coated jaws hold hybrid covered lines at loads up to 2350kg and resist heat generated at higher line speeds for extended jaw life.
Construction and Materials
Lightweight Design: Features a lightened handle and body, locally reinforced with unidirectional carbon fibre.
Titanium Components: Critical components are constructed from Titanium for superior strength and weight savings.
Stainless Steel Option: Available with 17-4PH stainless steel parts for teams competing in classes where Titanium is prohibited.
Bearing System: Internal Torlon roller bearings ensure lasting performance and durability under high loads.
Installation and Maintenance
On-Deck Access: Allows easy access for removing the complete internal assembly even when banked together.
Flushing Ports: Includes access ports for fresh water flushing to maintain internal cleanliness.
Mounting Options: Side mounting is the neatest solution for spars, side decks, and coamings. Available in handed port or starboard configurations. Use the bolted version for conventional installation or the bonded version for building directly into the deck or rig to save installation weight.
Color Variations: Available in black, silver, and amber versions.
Lock Open Mode: The XXC0812/L variant allows the line to run freely in or out with the handle closed. Ideal for applications such as spinnaker sheets and mainsheets where locking is rarely needed. Lifting the rear switch instantly applies clutching mode.

Selection Guide
XXC vs ZS: Choose the XXC for working loads and diameters that cannot be held reliably with conventional clutches but where the winch release of the ZS Jammer is impractical. Choose the ZS for bigger diameters and higher loads where winched release is a positive safety feature and instant release is unnecessary.
