ULTRA Side Pocket Anchor

Our ULTRA Side Pocket Anchor for fast setting and secure holding in demanding applications

The ULTRA Side Pocket Anchor is the result of long-term research and engineering development and is designed to set quickly and hold securely. Its geometry engages immediately on contact with the seabed and build holding power through a wide contact surface and strong fluke profile. The angled shank is designed to embed without resistance, supporting deeper engagement. The anchor is produced in different versions to match installation and performance requirements.

Design and construction of our ULTRA Side Pocket Anchor

The ULTRA Side Pocket Anchor is engineered to engage immediately: bent rear wings are described as forcing a scraping action as soon as the anchor touches the seabed, supporting instant “bite”. Thin fluke tips promote penetration, while the broad contact area and robust fluke profile are designed to deliver holding performance across different seabed conditions.

The angled shank slices through seabed material with reduced resistance, increasing embedding depth. A dedicated swivelling mechanism is described as self-cleaning and designed to operate smoothly over time without jamming.

Construction details

  • Engagement geometry: rear wings and fluke design for immediate seabed engagement. 
  • Shank: angled for resistance-free embedding and increased depth. 
  • Mechanism: self-cleaning swivel mechanism designed to avoid jamming (as described). 
  • Materials: premium stainless steels specified as 316L and 318LN, hand polished. 
  • Options: Standard or Compact – balanced or unbalanced configurations (as listed).

FAQs

What is a side pocket anchor?

A side pocket anchor is designed for vessels that store the anchor within a recessed pocket in the hull rather than on a conventional bow roller. This installation method requires a specific anchor geometry that supports reliable deployment, secure stowage, and smooth recovery while maintaining the vessel’s exterior lines.

What are the advantages of the ULTRA Side Pocket Anchor?

The ULTRA Side Pocket Anchor is engineered for fast engagement, deep penetration, and high holding power. Features such as the thin fluke tips, angled shank, and wide contact surface work together to help the anchor establish a secure hold quickly across a variety of seabed conditions.

How does the ULTRA Side Pocket Anchor achieve high holding power?

Holding power is generated through a combination of penetration depth and contact area. The ULTRA Side Pocket Anchor is designed to embed deeply into the seabed while its broad fluke profile creates significant resistance against movement, helping the anchor remain secure under load.

Why is deep seabed penetration important for anchor performance?

An anchor that penetrates deeply into the seabed can develop greater holding power and is generally less likely to drag when exposed to increasing wind or current loads. Deeper embedding also helps maintain stability when conditions change during an anchoring period.

What is the purpose of the self-cleaning swivel mechanism?

The self-cleaning swivel mechanism is designed to maintain smooth operation during deployment and retrieval by reducing the risk of debris accumulation and mechanical jamming. This can contribute to more reliable anchor handling over time, particularly in demanding marine environments.

Which vessels are typically suited for side pocket anchors?

Side pocket anchors are commonly found on larger motor yachts, superyachts, commercial vessels, and custom-designed boats with integrated anchor pockets. The correct anchor size and configuration should always be selected according to the vessel’s dimensions, displacement, and installation requirements.
