With the HARKEN electric conversion kit, you can turn your manual Radial 35ST winch into a convenient electric winch in no time. This set is specifically designed to upgrade existing non-electric winches—ideal for sailors who want more comfort and less physical strain on board.
The powerful 700 W (12 V) motor provides reliable assistance when trimming sheets and halyards, even under high loads. This upgrade makes sail handling significantly easier, especially on longer passages or in demanding conditions.
The conversion kit is not pre-assembled and is designed for self-installation. However, thanks to its custom fit for the HARKEN Radial 35ST, it integrates smoothly into the existing winch system. This allows you to modernise your setup without replacing the entire winch.

I needed to replace another Harken winch, but with a single speed. This specific 35.2 dual-speed model is slightly larger but has double the reduction ratio, which allows me to work less hard. Very simple installation.
