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).
