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 30QT and 40QT operate 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 Ronstan website.
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.

POWER RIBS™
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 non-abrasive drum surface extends the service life of running rigging and allows

NO TOOLS REQUIRED
Full disassembly and reassembly can conveniently be performed without the need for any tools. To remove the drum, pull back the spring-loaded release latch and a slight anti-clockwise rotation will allow the self-tailing arm to be lifted from the winch. From there, the drum can be removed from the winch center stem.
When completing reassembly in reverse order, an audible click confirms positive engagement between the self-tailing arm and bayonet notches on the center stem. These notches allow the self-tailing arm to be locked in one of eight positions at rotational increments of 45 degrees.

1. No tools required for configuration and servicing

2. Sprung self-tailing jaws to accept 7 - 12mm line

3. Aluminium centre stem, lighter weight compared to bronze stems

4. Low line entry due to gearing configuration geometry

5. Proven Andersen winch gearing configuration

6. QuickTrim™ patented self-tailing feature for rapid sail trim and smooth adjustment

7. Power Rib™ ensures a controlled grip at all times, whether tensioning or easing

8. Machined aluminium drum, stronger and lighter than traditional cast aluminium drums

9. Ball bearings carry the thrust loads, roller bearings carry the radial loads of the drum to minimize rotational friction
