20ST Orbit Winch 1 Speed
Ronstans Orbit Winches are the new benchmark in high performance alloy winches. With a combination of fresh design thinking and proven manufacturing expertise, Orbit Winches weigh significantly less and offer lower line entry heights than any other winch in their class.
Remarkably easy to service, they require no tools for disassembly or maintenance. The machined aluminium drums feature the same Power Ribs that many sailors will recognize from Andersen Stainless Steel Winches, well-known for their impressive line grip, smooth control, 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 smooth and controlled easing, even under high loads.
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's 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.
