The Type Of Marine Anchor

Fluke Anchor
(Danforth Anchor)

This type of boat anchor features two flat, pointed flukes that dig into the seabed. It is lightweight, easy to handle, and suitable for smaller boats in mud or sand bottoms.

Plow Anchor
(Delta Anchor)

Plow anchors have a single pointed fluke and a curved shape resembling a plow. They provide good holding power in various bottom conditions, including mud, sand, and grass.

Claw Anchor
(Bruce Anchor)

Claw anchors have three curved, pointed flukes that dig into the seabed. They offer excellent holding power and perform well in a variety of bottom types, including mud, sand, and rocky bottoms.

Mushroom Anchor

Mushroom anchors have a large, rounded top and a weighted base. They are boat anchors which are suitable for soft bottoms like mud or sand. However, they are not ideal for strong currents or high winds.

Grapnel Anchor

Grapnel anchors feature multiple flukes attached to a central shank. They are commonly used for small boats, dinghies, or as a secondary anchor. Grapnel anchors are effective in rocky or weedy bottoms.

Danforth Hi-Tensile Anchor

This type of mooring anchor is an enhanced version of the traditional Danforth anchor. It is made from high-tensile steel, which provides increased strength and holding power.

Stockless Anchor

Stockless anchors are large, heavy mooring anchor commonly used on larger vessels. They have a stockless design and provide reliable holding power in various bottom conditions.

Advantages of Stockless Achor for Ship:

1. Streamlined Design: Their absence of folding arms or flukes simplifies the anchor’s overall structure, allowing for smoother operation and reduced risk of entanglement.

2. Ease of Stowage: Stockless anchors take up less space compared to stocked anchors, making them more convenient for storage on board ships and boats.

3. Improved Holding Power: Stockless anchors are designed to provide high holding power.

4. Versatility: Stockless anchors are versatile and suitable for a wide range of vessel sizes and types.

5. Reduced Risk of Damage: The absence of folding arms or flukes in a stockless anchor reduces the risk of damage to the ship anchor itself, as well as to the vessel’s hull or other equipment during deployment and retrieval.

6. Quick Setting: Stockless mooring anchors generally have a quick-setting capability.

The Holding Power Of Ship Anchor

The holding power of a ship anchor refers to its ability to remain securely embedded in the seabed, effectively preventing the ship from drifting or dragging. Several factors influence the holding power of an anchor:

Anchor Type

Different anchor types have varying holding power characteristics. Plow anchors, such as the CQR or Delta, and claw anchors, like the Bruce anchor, are known for their excellent holding power in a variety of bottom conditions.

Anchor Weight

The weight of the marine anchor plays a significant role in its holding power. Heavier anchors tend to have better holding abilities as they can penetrate the seabed more effectively and maintain a stronger grip.

Anchor Design

The design of the anchor affects its holding power. Anchors with sharp and well-designed flukes or blades, along with a suitable shank angle, are more likely to dig into the bottom and resist horizontal forces.

Bottom Conditions

The type of seabed or bottom conditions where the anchor is deployed can impact its holding power. Anchors generally perform well in mud, sand, or clay bottoms. However, holding power may be reduced in rocky, grassy, or hard-packed surfaces where it can be challenging to achieve a secure grip.

Scope and Scope-to-Depth Ratio

Scope refers to the ratio of the length of anchor rode (rope or chain) to the water depth. A larger scope allows the anchor to set at a lower angle, enhancing its holding power. A scope of 5:1 (for example, 5 feet of rode for every 1 foot of water depth) is commonly recommended, but a higher scope may be necessary in rough conditions.

Setting Technique

Proper setting technique is crucial for maximizing holding power. This involves slowly lowering the ship anchor, allowing it to penetrate the seabed, and applying backward pressure to set it securely. Setting techniques may vary depending on the anchor type and bottom conditions.
