Boat Anchor Buyer’s Guide
If you own a boat, you’re eventually going to need to buy an anchor for the vessel. Larger boats may come with an anchor included in your purchase, while smaller boats may not feature it as standard equipment.
If you’re going fishing on the river, the gentle current will slowly push you downstream. If you want to hang out in the same spot for fishing, then you’re going to need to drop anchor to prevent the drift. It’s the same for sea-going vessels. If you arrive at a diving or fishing sport, you don’t want the current to drift you away from the diving sport or fishing venue.
An anchor prevents the boat from moving with the current, keeping you in the same spot. There are various styles and designs of anchors suitable for use with all types of vessels. Whether you have a small dinghy or inflatable, or a 40-foot cruiser, an anchor is an essential piece of equipment to help you enjoy your time out on the water.
This buyer’s guide gives you everything you need to know about choosing the right anchor for your vessel.
The Different Types Of Boat Anchors
There are several anchor designs, with each of them serving a different purpose for conditions and boat lengths. Let’s unpack the different types to give you a better feel for the right anchor for your boat.
Wing Anchor
A delta wing anchor is a heavy-duty model featuring a single triangular-shaped blade. This anchor also has a sharp end for better penetration and holding power. They are common models for sea-going vessels, and they often feature a self-launching design, meaning you don’t need to throw them overboard.
Mushroom Anchor
The mushroom anchor gets its name from its shape – it looks like a mushroom. You’ll drop this anchor head-first into the water, providing your boat with stable anchoring in all water conditions—the bigger and heavier the anchor, the better the holding power for your boat. Mushroom anchors are a great choice for long-term mooring, and they offer you easy deployment.
Claw Anchor
The claw anchor also features an obvious claw design and shape that’s easy to recognize. These models feature sharp claws that grip the coral or rocks on the bottom. They settle easily into the bottom, and they are fast and easy to set up, with plenty of holding power.
Fluke Anchor
The fluke anchor, otherwise known as the cruising or crown anchor, is a popular design. These models feature a compact design, with flukes maintaining a strong holding capacity in soft bottoms like sand and mud. They are easy to set up, but they lack holding power on rocky bottoms.
Grapnel Anchor
The grapnel anchor is a small and compact design typically suitable for smaller dinghies and inflatable and PWCs. These models have a folding design, and they often come with ropes, no chains, and ventilated bags for easy under-seat storage on your boat.
Plow Anchors
The plow anchor is similar in shape to the delta model. They resemble the form of a farming plow, and they are suitable for rocky bottoms. These models offer exceptional holding power, but they lack compact features, making them challenging to store on smaller vessels.
Choosing the Right Anchor Size and Weight
When selecting your anchor, it’s important to consider the weight and size of the model you’re looking at. For instance, choosing a delta model with an 8-lb weight is unsuitable for inflatable, PWC, or dinghy. They do better with larger boats over 13-feet in length, providing more holding power at sea.
The bigger and heavier the anchor, the more weight it can hold, but the more space it takes up on the boat. Bigger doesn’t always mean better.
If you have a smaller boat, look for models like grapnel anchors that offer you closure of the flukes to the anchor’s body and compact storage on board. It’s also important to note that the more robust anchor designs require use with a chain, which adds more weight to your boat.
Boat Anchor Gear
When selecting your anchor design, you’ll also need to consider the accessories like shackles, chains, and ropes.
Braided Nylon Anchor Rope
Anchors utilize either a chain and rope setup for larger boats or a simple marine rope setup for smaller models. We recommend going with a minimum of ½-inch rope for any boat over 18-feet in length. Look for nautical ropes featuring design and construction with a triple strand or a double-braided nylon material.
Nylon sinks, and it also stretches to accommodate the natural movement of the water and your boat. It’s a versatile and strong material that’s weather-resistant, and it won’t degrade with exposure to saltwater.
The anchor fid features a cone-shape that comes to a point, allowing the weaving of the anchor rope through other sections of hollow cord. Unless you’re splicing the rope, we recommend that you choose a double-braided marine rope for your anchor.
When choosing the right rope length, it’s a good idea to measure three feet of rope for every 1-foot of depth. So, if you are out at a location where the bottom is 100-foot deep, you’ll need a 300-foot marine rope for your anchor.
If you’re anchoring overnight in harsh weather conditions, then this ratio will extend to 7:1, meaning you’ll need a 700-foot marine rope for a 100-foot bottom depth. Most captains utilize a ratio of 400-feet of water depth with a 600-foot rope and 75-foot chain. The best move is to use a longer chain to let the anchor pull horizontally across the ocean floor.
Anchor Chain
The chain for your anchor needs to be longer than 15-feet. The chain serves a dual purpose for the anchor. First, it prevents the anchor rope from lying on the sea bed where it might catch on a sharp coral and sever the rope.
Secondly, the chain serves the purpose of pulling the anchor horizontally, preventing the anchor from dislodging from the bottom. The general rule for choosing your chain length is to have one foot of chain for every foot of boat length.
So a 25-foot boat would need a 25-foot chain for your anchor. Another popular rule is to choose one foot of chain per 6-feet of anchor marine rope. So, each 100-feet of marine rope will require at least 17-feet of anchor chain for the best results.
This setup is suitable for rough ocean conditions and the long-term mooring of your vessel. The chain weight is also important if you have a small diameter chain. Your anchor chain should feature design and construction with galvanized steel to prevent corrosion and rust in seawater. Make sure you rinse the chain and anchor after each use. While the galvanized options are durable, they will start to rust if you don’t rinse them after use.
Anchor Windlass
The windlass makes retrieving the anchor easy. Without a windlass, it could take two people the retrieve the anchor from the water.
When setting up your windlass, the electrical wires must run to the boat’s batteries. It requires secure mounting to prevent dislodgment and accidents on the water when retrieving the anchor.
Anchor Buoy With Anchor Ball Ring
The anchor ring puller features an 11-inch or 15-inch buoy, allowing you to float between 30 to 60-pounds from the buoy. You have various color options for your buoy. Still, we recommend going with a hi-viz orange or yellow color to allow for easy identification in misty weather offshore or on the lake.
If you are out fishing in water depths deeper than 350-feet, we recommend using a buoy line anchor setup for the best results with retrieving your anchor and monitoring it while fishing. A size A-3 anchor ball is close to a 15-inch buoy size, and the anchor ring comes in two sizes to suit your needs.
- The 1/4 inch stainless steel ring is for anchors weighing up to 20-lbs.
- The 5/16 inch stainless steel ring is for anchors weighing up to 80-lbs.
Anchor buoys are sold separately to your anchor and marine rope or chain, and they come in a range of sizes to suit your needs and water conditions. The most common type of anchor buoy is the polyform A-series. They are available in the following sizes to suit your anchor’s requirements.
- A-0 – 11.5 inches.
- A-1 – 15 inches.
- A-2 – 19.5 inches.
- A-3 – 17 x 13 inches.
- A-4 – 20.5 x 27 inches.
- A-5 – 27 x 36 inches.
These buoys are available in various colors, with orange, red, black, blue, white, and yellow available to suit your requirements. If you’re anchoring in water deeper than 350-feet, we recommend using an anchor buoy with an anchor ring, especially if you’re not using an anchor windlass.
You’ll set it up by weaving the anchor line and carabiner clip through both of the loops at either end of the ring. It’s best to ensure you do this on shore before heading out to sea to reduce the chances of things going wrong out on the water.
Make sure you secure the anchor line to the front of the boat using a cleat with the anchor line outside of the boat’s railings. It’s critical that you don’t tie the anchor rope to the back or middle of the boat, as this could present a capsize risk in rough water conditions.
Drive your boat forward and slightly to the one side of the marine rope, ensuring you don’t run over the rope with the motor propellers. The anchor buoy slides down the line until it’s vertical with your anchor. The natural forces pull straight up the anchor, freeing it from the bottom.
After the anchor frees itself from the bottom, check that the anchor slides up the line to the anchor ring. Stop the boat and pull your anchor up to the boat by hand.
Boat Anchor FAQs
Q: What is the best style of anchor for my boat?
A: The type of anchor required for your boat depends on where you intend on taking your boat and the boat model. Other factors to consider are your mooring times and the type of bottom. Larger boats with cross-over functions for fresh and saltwater use may require two anchor types onboard the vessel for optional anchoring in all conditions. Each anchor comes with different uses and specifications to suit your boat and your needs out on the water.
Q: What kind of bottom conditions are suitable for anchors?
A: The bottom conditions between lakes, rivers, and the ocean are very different. As a result, you need the right anchor design for the best holding capacity and strength in each bottom condition. Grapnel anchors feature spikes sticking out to the sides, and they grip rocks and solid objects under the water. Fluke-style anchors can dig into mud and sand for optimal holding power, while a claw or plow anchor is effective at digging into sandy or mud bottoms or latching onto coral at sea.
Q: What is the best size anchor for my boat?
A: Most anchor manufacturers recommend you stick to 1/8-inch of rope per 9-foot of length for your boat. Using a small diameter rope helps save space on smaller boats, but we don’t recommend that you go under a 3/8-inch diameter for your marine rope. Inflatables and kayaks will get the best results from a 1/8-inch marine rope. A 3/8-inch diameter marine rope is suitable for those boats measuring under 18-feet in length. Use a ½-inch rope for boats measuring 19 to 25-feet, a 5/8-inch rope for boats measuring 26 to 45-feet, and a ¾-inch rope for boats 46 to 54- feet.
Q: What length of a marine chain do I need for my anchor?
A: You have three guidelines for selecting the right chain or rope length for your anchor. The first rule of thumb is that the anchor chain or rope should be no less than 15-feet in length, regardless of the boat size or the design. The second rule is that the anchor chain or rope should feature at least one foot of length for every foot of boat length. Finally, the third rule is for the anchor to have at least one foot of chain per six feet of anchor rope. So, you’ll need around 1000-feet of marine rope for every 17-feet of anchor chain.
