A reliable anchor is one of the most critical pieces of safety equipment on your boat. It provides security when you need to stop, whether for a quiet lunch in a sandy bay, a fishing trip over a reef, or an unexpected engine issue. But with so many different types and sizes available, choosing the right one can feel overwhelming.
This guide is here to help. We’ll walk you through the key factors to consider, explain the most common anchor types used by Australian boaters, and help you understand how to build a complete anchoring system. Making an informed choice will give you the peace of mind to enjoy your time on the water, knowing you have a secure and reliable Boat Anchor ready for any situation.
What to Consider When Choosing a Boat Anchor
Selecting the right anchor isn’t just about picking one off the shelf. Several factors come into play to ensure you have the best holding power for your vessel and boating style.
Mooring Conditions
The type of seabed you anchor in is the most important consideration. An anchor that holds firm in soft sand might struggle on a rocky bottom. Think about where you do most of your boating.
- Sand and Mud: Soft seabeds require an anchor that can dig in deep to get a firm grip.
- Rock and Coral: Here, you need an anchor that can hook onto the structure without getting permanently stuck.
- Changing Conditions: If you frequent various spots, a versatile, all-round anchor is your best bet.
Boat Size and Weight
Your boat’s size and displacement (its total weight) determine the size of the anchor you’ll need. A heavier boat creates more force on the anchor, so it needs a larger, heavier anchor to hold it securely. Always check the manufacturer’s recommendations for your specific boat model.
Tides and Currents
Areas with strong tides or currents put extra strain on your anchoring system. In these conditions, it’s wise to choose an anchor that is one or two sizes larger than what’s recommended for your boat size. This provides an extra margin of safety and ensures your boat stays put.
Single vs. Dual Anchors
In most situations, a single anchor at the bow is sufficient. However, there are times when two anchors are better than one. When beaching your boat, for instance, using an anchor at the bow and another at the stern will keep your vessel straight and prevent it from swinging with the wind or waves.
Types of Boat Anchors
We’ve handpicked a selection of the most common anchor types used in Australia to help you find the perfect match.
Sand Anchors
As the name suggests, sand anchors are designed for soft seabeds like sand and mud. They are a favourite among Australian boaters due to their excellent holding power in these common conditions.
- How they work: Their design allows them to penetrate deeply into the soft ground, creating strong resistance that holds your boat in place.
- Features: Most sand anchors are hot-dipped galvanised to protect them from corrosion in the saltwater environment. Many also include a retrieval eye, which makes it easier to dislodge the anchor if it gets snagged on an underwater obstacle.
Reef Anchors
If your adventures take you fishing or diving near rocky bottoms or coral reefs, a reef anchor is an essential piece of kit.
- How they work: Reef anchors have multiple prongs (or tines) that are designed to grip onto the uneven surfaces of rocks and coral.
- Features: A key feature of reef anchors is that their prongs are designed to bend under pressure. If the anchor gets stuck, you can apply force to bend the prongs and retrieve it, saving you from losing it to the sea. Like sand anchors, they are typically hot-dipped galvanised for durability.
Plough & Delta Anchors
Plough and Delta anchors are excellent all-rounders, known for their versatility and reliable performance in sand and mud.
- How they work: Their unique, curved shape allows them to set quickly and dig in securely. They are also known for maintaining a strong hold even when the tide or wind direction changes, which helps prevent the anchor from dragging.
- Features: These anchors, including trusted brands like Lewmar, are available in both galvanised and stainless steel finishes. Stainless steel offers superior corrosion resistance and a polished look, while galvanised steel provides a more cost-effective, durable option.
Self-Aligning Anchors
For boaters who demand the highest level of performance, self-aligning anchors are the premium choice. Brands like Rocna and Sarca are leaders in this category.
- How they work: These advanced anchors are engineered to roll themselves into the correct orientation and set immediately, no matter how they land on the seabed. This ensures a fast and reliable hold every time.
- Features: Offering exceptional reliability, self-aligning anchors are perfect for serious cruisers who face a wide range of conditions. They come in both marine-grade stainless steel and hot-dipped galvanised finishes to suit your needs and budget.
Building Your Complete Anchoring System
A boat anchor is only as good as the system supporting it. To ensure maximum safety and performance, you need to pair your anchor with the right rope and chain.
- Anchor Rope: Nylon and polyester are the most common materials for anchor ropes. Nylon offers excellent elasticity, which helps absorb shock from waves and wind, reducing the strain on your boat and anchor. Polyester is also strong but has less stretch.
- Anchor Chain: A length of chain between the anchor and the rope provides several benefits. Its weight helps the anchor shank lie flat on the seabed, allowing it to dig in more effectively. The chain also protects the rope from abrasion on rough seabeds. Galvanised chain is a durable and popular choice, while stainless steel offers the ultimate in corrosion resistance.
- Anchoring Kits: For a hassle-free setup, consider a pre-assembled anchoring kit. These kits typically include a sand anchor, rope, and chain, providing everything you need to get started.
