FEATURES

  • Sprung self-tailing jaws to accept 8 - 14mm line.
  • QuickTrim™ patented self-tailing feature for rapid sail trim and smooth adjustment.
  • Ball bearings carry the thrust loads, roller bearings carry the radial loads of the drum to minimise rotational friction.
  • Proven gearing configuration. Power Rib™ ensures a controlled grip on the line at all times, whether trimming or easing. Minimal rope wear compared to more abrasive drum surface finishes.
  • 45QT and 50QT available as three-speed models.
  • Machined aluminium drum – stronger and lighter than traditional cast aluminium drums.
  • Lightweight aluminium centre stem provides significant weight savings over traditional bronze stems.
  • Low line entry due to gearing configuration geometry.

 

THREE SPEED MODE

Featuring the fastest line speeds in our range, Ronstan three-speed Orbit Winches™ offer significant advantages in many racing and cruising situations that require rapid line retrieval. In the initial stages of trimming or hoisting sails, the high-speed first gear reduces the time and effort required to adjust sails efficiently. After quick initial line recovery at low load, the winch can be shifted to the slower second and third gears as load increases, using theirgreater mechanical advantage for precise control of heavy loads.  The added versatility provided by the extra gear results in improved performance and safety on the water.

To engage the first gear with a fast 1.4:1 gear ratio, push the button on top of the winch and turn the winch handle clockwise. When the load becomes too heavy, turn the handle anti-clockwise to switch to the second gear. The winch will now operate as a two-speed winch, shifting between second and third gear with changes in handle direction. To return to the first gear for extra speed, simply push the button again.
