The ULTRA anchor swivel is a pinnacle of anchoring technology, designed to simplify anchor handling and enhance safety. This device combines the functions of a swivel and an articulated joint, meaning it provides full 360° rotation around its axis along with a degree of bending (pivot) between the anchor and chain. The result: no matter how your anchor lands on the seabed or twists during retrieval, the ULTRA swivel will guide it into the correct orientation as it comes onto the bow roller.
Exceptional construction: Each ULTRA swivel is crafted from high-strength 316 stainless steel, and the material is not cast but machined/forged for maximum toughness. This eliminates the risk of hidden porosity or brittleness – the unit is not fragile and can withstand shock loads. The internal mechanism is simple and dependable – no unnecessary moving parts to corrode or jam. Manufacturer tests and certification by RINA (Italian Naval Registry) show that the breaking load of this swivel exceeds the breaking load of the equivalent anchor chain (i.e., the chain would fail before the swivel does).
Specially designed for ULTRA anchors: This model is engineered to complement ULTRA’s premium anchors, but it’s also compatible with other anchors of similar shank design. The swivel attaches directly to the anchor via its built-in bolt/axle – no separate shackle needed. There are also no additional safety pins – the unique locking system keeps the connection secure with no risk of loosening under load.
Available Sizes: The ULTRA swivel comes in multiple sizes to match different chain diameters and anchor weights:
- 00241-06: Length 121 mm, for chain Ø6 mm (up to 8 mm), recommended for anchors up to ~12 kg (approx 25 lbs).
- 00241-08: Length 147.5 mm, for chain Ø6-8 mm, suitable for anchors ~12–16 kg (30–35 lbs).
- 00241-10: Length 168 mm, for chain Ø8-10 mm, suitable for anchors ~16–20+ kg (35–45+ lbs).
- 00241-16: Length 250 mm, for chain Ø12-16 mm, built for very large anchors ~30–60 kg (66–132 lbs) on big yachts.
All versions share the ULTRA design advantages – strength, flexibility, and corrosion resistance. In practice, installing an ULTRA swivel eliminates common anchoring issues: your anchor won’t come up upside-down or sideways, your chain won’t develop twists over time, and your windlass operates with less strain. Plus, the polished finish and precision build lend a luxury appearance to your bow gear.
The ULTRA Marine manufacturer provides a 3-year warranty on this product, underscoring its long-term reliability. It’s an investment in hassle-free anchoring: with the ULTRA swivel, anchor deployment and retrieval become faster, smoother, and safer in all conditions.
