Lewmar Anchor Swivels

Lewmar Anchor Swivels: Engineered to Keep Your Rode Running Clean

When you drop the hook in a rolling anchorage, the last thing you want is a twisted, kinked rode jamming your windlass or fouling your anchor shank. That's exactly the problem that Lewmar anchor swivels are built to solve — and they do it with the same uncompromising material standards that have defined the brand since its founding in 1946.

Since 1946, Lewmar Marine has been crafting marine equipment, originally specializing in dinghy fittings before evolving into a leading supplier of anchors, winches, windlasses, hatches, hardware, rigging, and steering systems. That deep anchoring expertise carries directly into their swivel line.

What Makes Lewmar Anchor Swivels Stand Out

Lewmar anchor swivels are heavy-duty stainless steel components designed to keep the rode — whether rope or chain — from twisting and wrapping itself around the anchor shank, and can be connected between the line and chain or between the chain and anchor.

Lewmar stainless anchor swivels are made from 316 stainless steel to hold up in marine environments and provide complete 360° swivel capability. Grade 316 is the go-to alloy for saltwater hardware because of its elevated molybdenum content, which dramatically improves resistance to chloride-induced corrosion — critical for gear that lives at the bow in spray and surge.

The swivels are welded for high strength and include stainless steel screw pins — construction details that matter when a storm rolls through and the full force of the vessel loads up on the ground tackle.

Lewmar's Fixed Swivel Product Line

Lewmar offers anchor swivels in two key fixed-swivel models sized to cover the most common recreational and offshore chain diameters:

• SWIVEL312F — designed to keep anchor chain from 1/4" and 5/16" (6.0 and 8.0 mm) from twisting, crafted from premium 316 stainless steel for durability and resistance to harsh marine environments. It supports a working load of up to 4,500 pounds, ensuring reliability in various sailing conditions.
• SWIVEL500F — crafted from durable 316 stainless steel, designed to handle heavy loads while maintaining flexibility in challenging conditions. It fits chain sizes of 3/8", 1/2", and 7/16" (10.0, 12.0, and 11.0 mm), making it versatile for various marine applications.

Both swivels include stainless steel screw pins and 360-degree stainless steel swivel pins, allowing anchor rodes to spill easily out of the locker when deploying.

Why Pair a Lewmar Swivel with Your Lewmar Ground Tackle

Lewmar Marine is a globally recognized leader in marine equipment, delivering high-quality solutions for both recreational and commercial vessels — from anchors and windlasses to hatches, winches, and steering systems. Running a Lewmar swivel in line with a Lewmar anchor and windlass means your entire ground tackle system is designed and spec'd to work together, matching load ratings, chain dimensions, and deployment characteristics end to end.

Best used for connecting an anchor to a chain, the swivel prevents chain kinks and tangles, providing smoother deployment and retrieval of your anchor — whether you're power-retrieving with a windlass or hauling by hand. For any boater serious about reliable anchoring, a quality swivel is the small fitting that protects the big investment.
