ULTRA Products by Boyut – exclusive European distribution by cromox®
The Swivels category covers critical connection components between anchor and chain. In an anchoring system, a correctly selected swivel supports controlled articulation, helps reduce unwanted torsion in the connection, and can improve how the anchor aligns and seats during retrieval.
Your swivel selection should match the chain diameter and anchor weight as defined in the respective selection tables. For safe long-term use, follow the provided safety and inspection guidance and avoid undersizing. Use the selection documents on each product page to specify correctly.
The ULTRA Flip Swivel is a one-piece, machined stainless-steel swivel designed to connect chain and anchor without additional shackles. Made from solid 316Ti stainless steel, its compact shape supports smooth passage at the bow during deployment and retrieval. A built-in flipping feature helps the anchor recover right-side up, supporting cleaner seating at the bow roller. The spherical joint provides controlled articulation with 360° swivel capability and up to 30° rotation as specified, and the breaking strength is stated as typically higher than the chain it is connected to. It is supplied with a standard 5-year warranty.
The ULTRA Classic Swivel is designed to connect Side Pocket and stockless anchors and support correct alignment during recovery. Machined from a single piece of solid 316Ti stainless steel, it combines high strength with controlled articulation at the connection point. The spherical joint allows 360° rotation and up to 30° tilt as specified, helping the anchor correct its position as it comes home. The breaking strength is stated as higher than the connected chain, and the swivel is supplied with a 5-year warranty.
A swivel is designed to connect the anchor and chain while allowing controlled movement between both components. By accommodating rotation and articulation, a swivel can help reduce torsional loads and support smoother anchor recovery.
During retrieval, an anchor may approach the bow from different angles or orientations. A correctly selected swivel can help the anchor rotate into a more favourable position, supporting cleaner seating at the bow roller and reducing the likelihood of misalignment.
A flip swivel incorporates a mechanism that helps rotate the anchor into an upright position during recovery. A classic swivel primarily provides controlled articulation and rotational movement, making it suitable for applications where flipping functionality is not required.
The swivel forms a critical connection point within the anchoring system and should be selected according to the chain diameter, anchor weight, and expected loads. Proper sizing helps ensure reliable load transfer and long-term operational safety.
A one-piece machined swivel is manufactured from solid material rather than cast components. This manufacturing method can provide greater dimensional accuracy, consistent material properties, and high mechanical strength for demanding marine applications.
A swivel with 360° articulation is designed to rotate freely around its axis while also accommodating movement between connected components. This flexibility helps minimise chain twist and supports smoother operation during anchor deployment and recovery.
Yes. One of the primary functions of a swivel is to reduce torsional forces within the anchoring system. By allowing controlled rotation between the anchor and chain, a swivel can help minimise chain twisting and improve overall system handling.
