Lewmar 16AST & 16CST Single Speed Self-Tailing Winches
Models:
16AST– Single Speed Self-Tailing Aluminum Winch
16CST– Single Speed Self-Tailing Chrome Winch
Product Description
The Lewmar 16AST and 16CST Single Speed Self-Tailing Winches feature the innovative 'Wavespring' self-tailer design, combining gentle wave grip jaws with self-adjusting springs for secure handling of both modern smaller diameter lines and traditional larger Dacron ropes. A sleek, low-friction feeder arm ensures completely snag-free operation, making these winches ideal for precise sail control. Mount using 5 x M6 (1/4") countersunk screws on 94mm (3 11/16") PCD, with recommended rope entry angle of 5-10° to the base axis (base wedge may be required). Both models are made to order for custom marine applications.
