A plough anchor, also known as a plow anchor, is a type of boat anchor that is widely used for its ability to provide strong holding power in various seabed conditions. The design of the plough anchor includes a pointed and curved fluke resembling a plow or moldboard, which allows it to dig into the bottom and resist dragging.
Key features of a plough anchor include:
- Plough-Like Design: The anchor has a plow-shaped fluke that is pointed at the end and curves along its length. This design allows the anchor to efficiently penetrate and hold in different types of seabeds, including mud, sand, and gravel.
- Hinged Shank: Many plough anchors have a hinged or pivoting shank, which allows the anchor to adjust its angle based on the force applied during deployment. The hinged shank assists in setting the anchor securely on the seabed.
- Roll Bar: Some plough anchors are equipped with a roll bar or roll stabilizer. The roll bar helps the anchor self-right when it is lying on its side on the seabed, ensuring that the fluke is in the optimal position for setting.
- High Holding Power: Plough anchors are known for their high holding power, making them suitable for a variety of boats and conditions. They are particularly popular for use in larger vessels, cruising sailboats, and long-distance sailing.
- Versatility: Plough anchors are versatile and can be used in both freshwater and saltwater environments. Their design allows them to perform well in a range of bottom types.
- Materials: Plough anchors are typically made from materials such as galvanized steel or stainless steel to resist corrosion and enhance durability in marine environments.
- Retrieval System: Some plough anchors come with a retrieval system that allows boaters to dislodge the anchor if it becomes snagged on the seabed or underwater structures.
- Popular for Cruisers: Plough anchors are commonly used by cruising sailors due to their efficiency in holding power and adaptability to different conditions. They are often favored for their reliability during extended voyages.
Boaters should consider factors such as the type and size of the boat, local seabed conditions, and personal preferences when selecting an anchor. Plough anchors are well-regarded for their performance, and their design makes them suitable for a wide range of anchoring situations.
