ANDERSEN 50ST E1 Electric Full-Stainless Sailing Winch, 24V

The 50ST E1 is ANDERSEN's complete electric self-tailing winch in the 50-size, sold as a single unit rather than as a conversion kit for an existing manual winch. The 50ST is positioned for sailboats roughly 45 to 60 feet where the primary winches are sized to handle the loads from the main and the genoa on serious cruising and racing applications. The E1 designation calls out the single-speed electric drive with the integrated contactor and controller built directly into the winch base. There's no separate control box to mount somewhere else on the boat. Internal contactors and the controller live inside the winch, which keeps the install neater and lighter than older electric winch designs that required a remote control box.

The motor is a European-engineered and manufactured series-wound design carefully matched to the gearbox for the specific 50-size winch. The matching is what delivers the dual-speed characteristic without a dual-speed gearbox. At low load (sheeting in slack line) the motor runs fast and the winch pulls quickly. At high load (the moment the sail loads up the line) the motor slows down and the winch delivers high torque for fine trim control. That speed-and-torque curve is what most sailors actually want from an electric winch. Smooth and quiet operation across the working load range is what separates ANDERSEN E1 from cheaper electric winches that bog down or run too loud under load.

The illuminated intelligent push button is the user-facing control. The button has an integrated LED that confirms power to the winch system is on, a hinged safety cover that prevents inadvertent operation if somebody steps on it, and an IP67 water-resistant rating that handles the wet cockpit environment of a serious offshore boat. The button also acts as a status indicator. When the controller intervenes (overload, thermal cutout, or other protection event), the button flashes a status code that tells you what happened, which makes troubleshooting much faster than guessing what tripped the system. The cable for connecting the push button to the winch ships in the box, so the install is straightforward.

Monitoring and protection is what most operators notice once they start using the winch in real conditions. Integrated overload protection stops the winch automatically if the maximum pull load is exceeded, with operation resuming within a few seconds once the load returns below the limit. This prevents the kind of damage that bringing a heavily-loaded line up against a stopped winch can cause. Thermal overload protection on the motor disables the winch if the motor temperature exceeds the safe operating range, which prevents the motor from burning out during sustained heavy use (a long upwind beat with the genoa heavily loaded, for example). Both protections reset automatically once conditions return to normal.

The full-stainless construction is the second defining feature of this SKU. ANDERSEN's standard winches use chromed bronze for some internal components. The Full Stainless (FS, also marked as the standard 50ST configuration) uses 316 stainless steel throughout the load-bearing components. For boats kept on long-term saltwater moorings or for owners specifying the best corrosion resistance, the stainless option is the long-term answer despite the slightly higher initial cost. Maintenance is also reduced because the stainless internals don't require the periodic re-chroming that bronze components eventually need on heavy-use boats. Installation is simplified by the integrated controller design: connect the positive and negative power cables to the motor terminals, connect the push button using the included cable, and the system is ready. ANDERSEN sells marine-grade circuit breakers separately for proper circuit protection and isolation.

One thing worth knowing about specifying an electric winch versus retaining a manual winch on a sailboat. For boats sailed short-handed (single-handed offshore work, two-person cruising), the electric drive is the difference between being able to bring in a heavily-loaded sheet at the end of a long day and not. Manual winches at the 50-size on a 50-foot boat with the genoa loaded up demand real strength, and even strong crew get tired by the end of an offshore passage. The push-button operation lets any crew member control the winch regardless of strength or fatigue. For boats sailed with full racing crews on short legs, manual winches are still the cleaner answer because the electric drive's slower top speed at low load isn't fast enough for short tacking duels. For 90 percent of cruising and short-handed applications, the electric drive earns its cost within the first season.
