Boomer Muscle Man Anchor Swivel

Boomer MuscleMan Anchor Swivel

The Boomer MuscleMan Anchor Swivel is a premium heavy-duty anchor swivel engineered to improve anchor performance, reduce chain twist, and eliminate dangerous side-loading during anchor deployment and retrieval. Designed and manufactured by Boomer Anchors, this robust swivel is the perfect companion for the Boomer All Terrain Anchor while also being compatible with many other leading anchor brands.

Manufactured from marine-grade 316 stainless steel, the MuscleMan Anchor Swivel is built to withstand the harsh saltwater environment. Its corrosion-resistant construction delivers exceptional strength and long-term reliability, making it ideal for recreational fishers, trailer boats, and offshore vessels that demand dependable anchoring performance year after year.

Unlike conventional swivels, the MuscleMan is specifically engineered to reduce the side-loading forces that can affect anchor performance. By allowing the anchor to self-align correctly during deployment and retrieval, it helps the anchor set more effectively while reducing unnecessary stress on the anchor shank, chain, and bowsprit. It also minimises chain and rope twisting, making anchor retrieval smoother and helping prevent tangles during repeated use.

Rated to an impressive Safe Working Load (SWL) of 2,500kg, the MuscleMan Swivel is suitable for boats using 6mm to 8mm anchor chain. Its heavy-duty construction provides confidence when anchoring over reef, sand, mud, or mixed seabeds, while maintaining smooth movement under load.

Installation is made simple with Boomer’s custom-designed oversized Allen key bolts, allowing for easier tightening and future servicing compared to many traditional anchor swivels. Both the required 5mm and 6mm Allen keys are included, making installation quick and straightforward straight out of the box.

Whether you’re anchoring for a day chasing SNAPPER, deep-dropping for HAPUKU, or spending the night at anchor, the MuscleMan Anchor Swivel provides smoother deployment, improved anchor alignment, and greater confidence every time you anchor.
