Andersen 46ST Compact Above Deck Electric Stainless Winch 12V
Andersen 46ST Compact Above Deck Electric Stainless Winch 12V — Product description
Andersen's compact above-deck electric winch in full stainless. The 46ST puts a brushless DC motor and integrated gearbox above the deck, so the topside stays clean while any crew member can hoist and trim sails at the push of a button regardless of physical strength.
The Andersen 46ST Compact Above Deck Electric Full Stainless Winch (MPN RA2046015100) is Andersen's 46-size electric self-tailing winch with the motor and gearbox configured for above-deck installation, 12-volt power, and Andersen's signature full-stainless construction. For sailing yachts where the helm and crew need push-button sail handling without the topside bulk of an above-deck motor installation, the above-deck configuration is the clean choice. The winch above the deck looks like a standard manual self-tailing winch, while the brushless DC motor and integrated controller sit out of sight below.
Why electric matters. Sailing yachts above 35-40 feet hit the practical limit of manual winch operation, particularly for grinding the genoa under load, hoisting a heavy mainsail, or trimming in heavy weather. Electric winches let any crew member, regardless of physical strength, hoist and trim sails at the push of a button. For shorthanded sailing, family cruising with non-athletic crew, single-handed operation, and any situation where you want to focus on sail trim rather than winch grinding, electric is the operational upgrade that transforms the sailing experience.
Andersen Compact Motor architecture. The Compact Motor combines a brushless DC motor with an integrated planetary gearbox and controller in one compact unit. No separate control box, no separate relay panel, no complex wiring topology. Connect positive and negative power cables to the motor terminals, connect the push button using the included output cable, and the winch is operational. For installs where electrical complexity matters (refit jobs, charter operations, owners who want serviceable systems), the integrated architecture is a significant operational advantage.
Brushless DC for efficiency and longevity. The brushless DC motor draws considerably less current than traditional brushed-motor or AC-motor winches, which reduces the load on the boat's house DC bus and extends battery runtime for sailing operations. Brushless motors also have longer service life than brushed alternatives, no brush replacement, no commutator wear, and reduced electrical noise. For boats where the winch is operated daily during a cruising season, the brushless architecture pays back in lower long-term ownership cost and reliability.
Variable-speed operation. The Andersen Compact Motor operates at variable speed in proportion to the pressure applied to the push button. Light press for slow precise operation (final sail trim, light loads), full press for fast hoisting and high-load grinding. The variable speed makes the winch behave like an extension of the operator's intent rather than an on/off motor, which matters for precise sail handling and avoiding shock loads on the sail or rig.
Illuminated intelligent push button. The included push button has an integrated LED that illuminates when power to the winch system is on, so you have visual confirmation of system status. A hinged safety cover prevents inadvertent operation. The push button is IP67 water resistant for exposed-cockpit installation. The button also acts with the controller to flash status codes for troubleshooting in the event of overload or system protection intervention, which makes diagnosis significantly easier than older winches with no operator feedback.
Integrated overload protection. The controller is pre-set to stop the winch if the maximum pull load is exceeded. Operation resumes automatically within a few seconds once the load returns below the limit. For situations where a sheet snags or a halyard hangs up during operation, the overload protection prevents damage to the winch, the line, the sail, or the rig. The auto-reset behavior means you don't have to walk to a circuit breaker to recover after an overload event.
Thermal overload protection. The motor includes a thermal cutout that disables operation if the motor overheats during prolonged high-load operation. Automatic reset once the temperature returns to normal. For long high-load operations (hoisting a wet mainsail, recovering from a tangle, prolonged grinding), the thermal protection prevents motor damage from overheating.
Full stainless construction. Andersen's signature is full-stainless winch construction, which delivers the corrosion resistance and finish that aluminum-bodied winches can't match in saltwater service. For boats where the winch is exposed to continuous salt spray, UV, and the rest of the marine environment, full stainless is the construction that lasts decades rather than years.
Above-deck install considerations. The motor and gearbox mount above the deck (typically in a locker, cabinet, or dedicated motor space directly below the winch position) with the winch drum mounted on deck through a standard winch base. Power cabling routes from the boat's house DC bus to the motor terminals (heavy gauge for high current draw). The push button cable routes from the operator position to the motor controller. Total install is a marine yacht installer day-plus for a clean job, including the deck cutout (if not already present), motor mounting, electrical integration, and commissioning. Not casual DIY because the deck cutout precision, structural backing, and electrical sizing all need professional setup.
Why pay this much. Three reasons. First, the 46ST is a serious electric winch sized for sailing yachts in the 35-50 foot range where manual operation hits practical limits. Second, the Andersen Compact Motor architecture (brushless DC, integrated controller, variable speed, intelligent push button, dual overload protection) is operationally meaningful, not just a spec sheet. Third, the full-stainless construction means the winch lasts the life of the boat rather than needing replacement every 5-10 years like aluminum-bodied alternatives. For owners building or refitting a serious sailing yacht where push-button sail handling matters operationally, the Andersen 46ST above-deck electric earns its position.

Frequently asked questions
Why above-deck instead of above-deck motor?
Topside aesthetics and clean deck. The above-deck configuration puts the motor and gearbox in a locker or cabinet directly below the winch, so the topside looks like a standard manual self-tailing winch. For sailing yachts where the cockpit needs to stay uncluttered and the deck stays clean, above-deck is the right choice. For boats with limited above-deck space, the above-deck Andersen Compact Motor configuration is the alternative.
What size boat is the 46ST sized for?
Generally 35-50 foot sailing yachts depending on the specific application (genoa winch, halyard winch, mainsheet winch) and sail plan. The 46-size is a serious electric self-tailing winch that handles typical cruising sail loads in this size range. For larger yachts or extreme high-load applications, Andersen's larger 58/68 sizes are the alternative.
Why brushless DC motor?
Three reasons. Lower current draw than traditional brushed motors, which reduces house DC bus load and extends battery runtime. Longer service life, no brush replacement, no commutator wear. Reduced electrical noise compared to brushed motors. For boats where the winch is operated daily during a cruising season, the brushless architecture pays back in lower long-term ownership cost and reliability.
How does variable speed work?
The motor speed is proportional to the pressure applied to the push button. Light press for slow precise operation (final sail trim, light loads), full press for fast hoisting and high-load grinding. The variable speed makes the winch behave like an extension of operator intent rather than an on/off motor, which matters for precise sail handling and avoiding shock loads.
What if the line gets snagged?
Integrated overload protection. The controller is pre-set to stop the winch if maximum pull load is exceeded. Operation resumes automatically within a few seconds once the load returns below the limit. The auto-reset behavior means you don't have to walk to a circuit breaker to recover. The push button flashes status codes during overload events for troubleshooting.
Can the motor overheat?
Thermal overload protection prevents motor damage. The motor includes a thermal cutout that disables operation if the motor overheats during prolonged high-load operation. Automatic reset once the temperature returns to normal. For long high-load operations (hoisting a wet mainsail, recovering from a tangle), the thermal protection prevents motor damage from overheating.
Why full stainless instead of aluminum?
Corrosion resistance and service life. Full stainless construction delivers the corrosion resistance and finish that aluminum-bodied winches can't match in continuous saltwater service. For boats where the winch is exposed to continuous salt spray and UV, full stainless lasts decades rather than years. The cost premium versus aluminum is paid back in not needing replacement.
What's the electrical installation like?
Simpler than traditional electric winches. No separate control box, no relay panel, no complex wiring topology. Connect positive and negative power cables to the motor terminals, connect the push button using the included output cable, and the winch is operational. For installs where electrical complexity matters, the integrated architecture is a significant operational advantage. Heavy-gauge wiring sized for the motor current draw is required.
Where does the push button mount?
Typically in the cockpit at the operator station for the winch (helm, navigator position, or dedicated winch operator location). The IP67 water-resistant rating means the button can mount in exposed cockpit positions without weather protection concerns. The included output cable handles the connection from button to motor controller above deck.
Can I install it myself?
Not recommended for most owners. The deck cutout requires precision for clean integration with the cockpit layout, structural backing under the winch base needs proper design for the dynamic loads, motor mounting above deck needs adequate space and access, and the electrical install requires heavy-gauge wiring sized correctly for the motor current draw. Plan a marine yacht installer day-plus for a clean job.
What's the 12V versus 24V choice?
Match the boat's existing house DC bus. Most sailing yachts in the 35-50 foot range run 12V house systems, so the 12V Compact Motor is the right pairing. Larger yachts and modern designs often run 24V house systems, in which case the 24V variant (different MPN) is the right choice. Don't run a 12V winch on a 24V system without proper voltage conversion.
What's the warranty?
Andersen standard warranty applies. Andersen's marine warranty service network is established for the stainless winch product line, with dealer support for installation and service. The full-stainless construction is part of the long-term value proposition, and the warranty backs the build quality.
