Ronstan RA6201 20ST Orbit Single Speed Self-Tailing Winch

The Ronstan 20ST Orbit Winch sets a new standard for high-performance alloy winches in marine applications. Combining innovative design with proven manufacturing expertise, this single-speed winch delivers exceptional performance while weighing significantly less than comparable models in its class. The remarkably low line entry height improves ease of use and efficiency on deck.

Power Ribs™ Technology:

The machined aluminum drum features Ronstan's distinctive Power Ribs™ technology, proven on Andersen Stainless Steel Winches. This unique ribbed profile provides exceptional line grip while minimizing rope wear. The superior grip requires fewer wraps around the drum, reduces load on the self-tailer, and encourages lines to slide smoothly upward to prevent riding turns. Even under high loads, the non-abrasive surface allows smooth, controlled easing.

Tool-Free Maintenance:

Complete disassembly and reassembly can be performed without any tools. Simply pull back the spring-loaded release latch and rotate the self-tailing arm slightly counter-clockwise to remove it from the center stem. The drum then lifts off easily. During reassembly, an audible click confirms positive engagement. The bayonet notch design allows the self-tailing arm to be locked in eight positions at 45-degree increments for optimal line routing.
