SPINLOCK: Built-In Digital Jaws for XX MK3


The XX0812 clutch is capable of holding and releasing loads up to 1800kgs. For 2010, the XX Mk3 has been re-engineered to exploit the very effective ‘Digital Jaw’ technology introduced this year (in the ZS Jammers) for holding blended-cover ropes.

Some of the latest performance ropes use polyester covers reinforced with high tensile Aramid, Technora or Dyneema fibre. The Mk3XX gives consistently excellent performance across the full spectrum of rope types and rigs, good for a 44’ X-Yacht up to a Grand Prix raceboat.

In developing the new XX gripping system, jaw weight has been reduced and jaw
engagement and release reconfigured for minimal friction.
This helps streamline handling at the fast line speeds of 7+ metres/second now demanded for bigger race sail hoists using driven pit winches as in TP52 and Mini Maxi classes. A ‘straight-through’ rope alignment, parallel to the deck ensures neater side-mounting.

The Mk3 XX uses the clever ‘Grip Switch’ feature developed on the award-winning ZR Jammer. This ensures useful ‘hands-free’ protection for faster and more controlled winched release, say of asymmetric spinnaker sheets and mainsheets under full load. As with the ZR, ‘Release’ or ‘Lock’ modes are clearly indicated by the up or down position of the switch lever.

The new XX Digital Jaw set is removable in one piece for service and is available as an upgrade for existing Mk2 XX models.
