Ronstan 45QT Orbit Winch - 2-Speed, QuickTrim

Ronstan 45QT Orbit Winch - 2-Speed, QuickTrim

Lightweight aluminium winch with QuickTrim self-tailer, 2 speeds, and Power Ribs for controlled grip on the line at all times.

Introducing Quicktrim

The innovative QuickTrim self tailer allows sailors to easily and safely ease line tension to make minor sail trim adjustments without having to remove the winch handle or take the line out of the self-tailer. Racing sailors can react and respond instantly to minor changes in wind direction or steering, providing an unmatched advantage when frequent sail trim adjustments are required. It’s also a nice convenience for cruising sailors.

On the water, using QuickTrim is intuitive and quickly becomes second nature. With one hand on the tail of the sheet, rotating the top cover of the winch anti-clockwise against spring pressure allows the self tailer to turn beneath it like a sheave as the rope is eased out, with smooth grip and control assured by the drum surface and Power Ribs. When the top cover is allowed to spring back, the self-tailer locks again and grips the line to resume normal use. This simple, reliable feature is a real advantage when making frequent minor adjustments to sheet and halyard tension.

As delivered from the factory, the Orbit 45QT operates as a traditional two-speed self-tailing winch. The QuickTrim feature is enabled by the user, simply by removing a single screw located within the self tailer. Step-by-step instructions are included in the Quick Reference Guide provided with the winch, and in the product manual available from the Support section of the website.

Power Ribs

Inspired by the distinctive drum profile of Andersen winches, Power Ribs have been incorporated into the fully machined drums of Ronstan’s Orbit Winches to deliver the same impressive line handling with maximum grip and minimal rope wear. The exceptional grip provided by the Power Ribs offers a multitude of benefits: requiring fewer wraps around the drum, reducing the load held in the self tailer, and encouraging the line to slide easily upward on the drum to avoid riding turns. The nonabrasive drum surface extends the service life of running rigging and allows for smooth and controlled easing, even under high loads.

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.
