Dutton-Lainson StrongArm® Electric Winch – 120V AC / 12V DC
The StrongArm® Electric Winch is built for demanding trailer and dock applications where a reliable, powered winch is essential. Its precision-engineered gear train delivers smooth, quiet operation session after session, while heavy-duty construction ensures it holds up in harsh marine environments.
Choose between a 120V AC model for dock or garage use where shore power is available, or a 12V DC model for on-the-road trailer use powered by your tow vehicle or a dedicated battery.

Parts Desk Insights
The StrongArm® is the right call when you need a step up from a basic strap winch — particularly for heavier boats or frequent launch-and-retrieve cycles where manual cranking becomes impractical. The 120V AC version is best suited for a fixed dock or garage setup where you have shore power and want push-button convenience. The 12V DC version is the go-to for trailering, wiring directly to your tow vehicle or a dedicated trailer battery. The included emergency crank handle is a valuable backup for power failures at the ramp. For best results, pair with a quality bow stop and a properly rated trailer roller or bunk system to reduce load on the winch during retrieval.
