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.

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.
