45QT and 50QT available as three-speed models.
Hard anodised aluminium drum and centre stem.
QuickTrim™ patented self-tailing feature for rapid
sail trim and smooth adjustment.
Machined aluminium drum – stronger and lighter
than traditional cast aluminium drums.
Grade 316 stainless steel shaft and pawls.
Ball bearings carry the thrust loads, roller bearings
carry the radial loads of the drum to minimise
rotational friction.
Lightweight aluminium centre stem provides
significant weight savings over traditional bronze
stems.
Aluminium bronze gears.
Proven gearing configuration.
Low line entry due to gearing configuration
geometry.
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.
THREE SPEED MODE
Featuring the fastest line speeds in our range, Ronstan three-speed
Orbit Winches™ o昀昀er signi昀椀cant advantages in many racing and
cruising situations that require rapid line retrieval. In the initial
stages of trimming or hoisting sails, the high-speed 昀椀rst gear
reduces the time and e昀昀ort required to adjust sails e昀케ciently. After
quick initial line recovery at low load, the winch can be shifted to
the slower second and third gears as load increases, using their
greater 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 昀椀rst 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 昀椀rst gear for extra speed, simply push
the button again.
Grade 316 and 2205 stainless steel axle pins.
Hard anodised aluminium self-tailing arm.
Glass-filled nylon jaws.
Self-lubricating acetal bearings.
