The Difference Between a Spek Anchor and a Hall Anchor

2025-02-28

What Is Spek Anchor

The Spek Anchor is an improved studless swivel Anchor of the Hall Anchor, widely used as a ship's main anchor. By optimizing the anchor head structure and center of gravity position, the design significantly improves the stability and operation convenience, which is especially suitable for the anchoring needs of modern ships.

Core structure and design features

1. Anchor head and anchor claw design

- The center of the anchor head is located below the center line of the pin shaft, and the anchor crown plate and reinforcing rib are added to the anchor crown to enhance the structural strength and optimize the force distribution.

- The Angle of the anchor claw is about 45°, and the two claws can rotate synchronously around the pin shaft, which makes it easier to turn to the ground when sinking into the earth, improving the efficiency of holding the ground.

2. Center of gravity and stability optimization

- By adjusting the center of gravity position of the anchor head, the anchor claw naturally faces up when the anchor is pulled in, and automatically turns over when it touches the hull plate, avoiding scratching the hull and solving the problem that the Hall anchor may rub the hull when recovering.

- No cross bar design simplifies the structure for easy storage, while strengthening the stability of the anchor grip with the subsoil through the anchor crown plate.

Key Differences From Hall Anchors

1. Structural improvement

- The center of the anchor head of the Hall anchor is located above the pin, while the Spek anchor moves the center of gravity of the anchor head down and adds the crown plate to make it easier for the anchor claw to steer toward the subsoil.

2. Operation safety

- The Hall anchor can get caught in the hull when the anchor is being pulled in. The Spek anchor completely solves this problem by adjusting the center of gravity.

3. Grip stability

- Spek anchor is not easy to roll over when the flow is turned or the bottom material is uneven, and the pulling resistance is stronger.
