Marine Spek Anchor | Self-Balancing Stockless Anchor

A balanced stockless anchor designed to protect your hull. During retrieval, the flukes automatically pivot upward. This smooths the stowing process and prevents the flukes from scratching the ship’s paint. You get a reliable anchor that is simple to operate and gentler on your vessel.

Overview
Our Spek anchor is an improved version of the Hall anchor. Its main working principle is its self-balancing design. The anchor head is designed so that when the shank is lifted, the flukes automatically tilt towards the hull. This orientation allows the anchor to slide smoothly into the hawsepipe pocket. You avoid the common problem of flukes catching or scraping the bow. Its holding power is consistent and reliable for general-purpose use.

FAQ :

Q: How does the balanced design help during anchor retrieval?

A: The center of gravity is located to make the flukes tilt upward when lifted. This prevents the sharp fluke points from dragging against the ship’s bow as the anchor is pulled into the hawsepipe.
