How to Choose the Best Boat Anchors?

best boat anchors - banner

Your boat anchor is one of the most important tools you can have aboard—and overboard too! These special objects are specially designed to sink to the ocean floor, find purchase, and keep your vessel held tightly in place. Anchors are there to stop your boat from drifting away, as the current, tide, and wind try to push and pull it on its way.

Anchors can be dropped when you’ve located a prime fishing spot, or when you’ve decided to take a break and have a spot of lunch, or over a dive site. Stronger anchors can be dropped at nightfall, to keep you locked in place while you sleep, or to keep your boat in place for permanent mooring.

They can be used in freshwater rivers and lakes, as well as in the ocean, and these anchors have to deal with the tricky rivers, lakes, and sea beds which come in an enormous variety of conditions. Sand, mud, rock, and weed beds all require different anchor types to ensure the best hold.

With so much to think about, it’s no wonder that shopping for a new boat anchor can be an overwhelming experience. To make life a little easier, we’ve put together a list of some of the best boat anchors currently available, with a handy buying guide to help you make an informed decision when you’re shopping around.

How to Choose Boat Anchors?

Boat Anchor Types:

Down below is a list of some common boat anchor types so that you can understand which type you should choose from. Continue reading to know more about them.

1. Fluke Anchor

This is the most common one in use, alternatively known as Danforth or lightweight anchor. They are capable of setting in very well, thanks to their wide design and steel construction.

Moreover, they can usually keep the boats in their places, and are mostly used for the small ones. These can adapt to every ground condition but are undoubtedly the best boat anchor for sand.

2. Plow Anchor

If you want an anchor for larger boats, then plow anchors are the kind you should go for. They come with a superior holding power, which provides the capability of holding more substantial vessels.

Furthermore, it also provides more length and comes with a hinged design. So, storing the tool can be quite tricky. Also, to set into the bottoms, they burry themselves and create a hold.

3. Wing Anchor

Wing anchors have a similar shape to that of plow anchors. They even have the same holding power as their plow counterparts; except, they can be a little heavier. As a result, they can work with larger boats.

Since they are quite heavy, they use their weight to set and hold. However, not all tools of this kind are heavy. You can find some lightweight ones for small boats.

4. Claw Anchor

If you want an anchor to set in rocky bottoms specifically, then claw anchors are the kind you must go for. Unlike its other counterparts, it can stick well in coral and rock. Its wide three-claw design makes this phenomenon possible and even easy. However, this one has the smallest holding power amongst all the types. Hence, you will need a weighty claw anchor to hold a decent-sized boat.


What to Look for before buying?

If you are set to go on a boat ride, then you must choose an anchor that will prevent the boat from drifting away on the water surface. It may seem as if the task of finding an apt one is easy, but that is not always the case.

When choosing an ideal anchor for your boat, there are some fundamentals that you should not overlook. And we have mentioned them right here, to make the selection process much easier for you.

1. Anchor Types 

The first thing to determine is the type of anchor you will be needing. Different kinds are suitable for different bottom conditions, boat weight, etc. Some would be fit for rough weather, whereas others will only hold well if there is no current.

After considering all of these factors, you should select the kind you need and then proceed to choose the perfect anchor for yourself. However, it is safe to carry two separate anchors at all times. Therefore, you should choose two distinct ones to avoid risks when you are out at the sea or the ocean.

We have already mentioned the most common and widely used anchors for you. They are all distinct and suitable for various water and bottom conditions. After determining your preferences and needs, you should purchase the type that truly fits your criteria.

2. Weight Range of the Tool

When choosing the weight range for an anchor, there are a lot of factors to consider. In some cases, a heavy one might sound appealing, whereas, in others, you may prefer a lighter option. However, the weight range only depends on a few key elements. And you should keep them in mind.

The first and foremost factor, in this case, is the weather you will be anchoring in. Stormy or rough weather generally means that the currents are going to be fast. Mostly, in such cases, you should go for a heavy tool. Of course, in a better condition, a lighter tool will suffice.

While a bigger anchor may seem like a better idea, that is not always the case. A heavier size also means that you may have a hard time when raising it. Hence, a small and efficient one may prove to be less hassle-some at times.

Another factor is the size of your boat. However, you will not have to struggle in this sector as much because manufacturers usually suggest anchor weight range in accordance with the boat size.

The location of your boat rides also plays a role here. This gives a clue on the bottom condition the tool will be dealing with, as well as the water condition. Although, that is something we will discuss later on.

3. Holding Power of the Anchor

If you think that the weight of an anchor determines the holding power of it, then you couldn’t be further from the truth. The weight has little to no impact whatsoever on the power and should be viewed as a separate factor.

That is because, when the tool penetrates the surface of the bottom, a suction is created. This, in turn, combines with the tool’s weight and provides resistance. That resistance is generally known as the holding power.

However, setting into coral or rocky bottoms can be a little tricky. In that case, the tool can hold on to the rocks to stabilize the boat. The ability to do so also depends on the tool’s power.

Usually, you will get plenty of information on this while choosing the tool. That is, look for the holding power of the product in the manual. By this, you will be able to know whether or not it will hold your boat. A 10-pound anchor might as well be able to hold a boat that weighs 3000 pounds. Hence, this is one element you must prioritize.

4. Ground Conditions

Different anchors are designed for different sea beds. Ultimately, it is your responsibility to figure out the kind of ground condition the tool will have to deal with the most. If you cruise on a lake with a rocky bottom and buy one that works better in the sand, then you would only have yourself to blame.

Hence, here’s some useful information on the various types of bottom conditions to help you make a better decision. A sandy surface is the easiest to set in. Most types of anchors penetrate well in it. However, fluke anchors are the best choice for sandy bottoms. In hard sand especially, there will be a higher tension on the tool and hence, a greater holding power.

On the other hand, muddy bottoms are quite risky. They need anchors that can set in more securely. These surfaces usually have less shear strength. Hence, a broader fluke angle would be necessary for sticking into it properly. Coral and rocky bottoms are usually not easy to stick to. Therefore, you should get a grapnel or a plow anchor for it. These usually generate a lot of power, so you won’t be facing any problems.

Grassy or clay bottoms are quite challenging to set in. Unlike other types of sea bottoms and surfaces, this one requires a greater weight of the anchor for a better hold. So, the best boat anchor for the grassy bottom will undoubtedly be the one with the larger size.

5. Durability

Wouldn’t it be quite disappointing if your anchor decides to fall apart right when you are about to raise it? If you want to avoid such accidents, you need to make sure your chosen tool comes with top-notch sturdiness. It should not break down easily, and more importantly, it should not rust or corrode.

To make sure of all these, you need to keep an eye on the material used to make the tool. Both affordable and expensive materials can guarantee durability, but you need to check the authenticity of those. Galvanized steel is a cheap yet hard-wearing material. With this, your anchor will neither rust nor corrode.

Rather, it will last for quite a while. However, they are quite light, so if you want to go for heavier options, you will have to choose other materials. Stainless steel is another amazing option. They are moderately expensive and similarly prevent rust and corrosion. The best part is, since they have high tensile strength, they will not wear down or break apart easily.

If you want to prioritize weight above everything else, then you should choose an anchor made from aluminum or magnesium. These materials are really heavy. Furthermore, you will need to pay some extra bucks if you choose this.

6. Storage Options

This is not one of the most important factors, but storing your anchor in a secure place will keep it safer. Some of these come with a durable nylon bag. They are long-lasting themselves and protect the tool at all times.

Even if a case is not provided, you can purchase an extra one yourself. They are not supposed to cost much, but they will go a long way. Moreover, most anchors can be stored under boat seats. The big ones, however, have a little trouble with storage.

Let’s take a look at the top anchors out there, that are guaranteed to keep your vessel locked in position, no matter the conditions!

 2. Danielson Galvanized Folding Anchor

Buy now

If you’re looking for a budget anchor to keep your boat steady while you’re out on the water, then the Danielson anchor might be the solution. Ideal for lightweight, inflatable boats and kayaks, and for use on calm waters, this item from Danielson is a folding anchor that’s available in two sizes: 1.5 lbs, and 3 lbs. In all honesty, the smaller version isn’t very useful at all. The 3 lb model is far more usable.

This anchor is small and compact, measuring only 7 inches in length, and weighing only 3 pounds. It’s a folding grapnel-style anchor that has four flukes that can be released for better-grabbing power, though it works fine without the mechanism being activated too.

It is cheap, and it is very lightweight, so you shouldn’t have massive expectations from this anchor. It’s great for keeping you in place while you’re aboard your lightweight float tube, pontoon boat, or kayak, during calm and mild conditions but it’s not going to hold your super yacht in place during a squall.

This anchor features a ring for the attachment of a rope, but many users of this rope favor the use of a chain instead since it adds a little more weight to the anchor. For lightweight use, for lightweight vessels, in gentle conditions, this is a very affordable boat anchor that won’t let you down.

  • Anchor Type: Folding, Grapnel
  • Anchor Dimensions: 7” long
  • Anchor Weight: 3 lbs
  • Material: Galvanized steel

Our last inexpensive folding anchor is this gem from Airhead. It’s a lightweight, folding grapnel anchor that’s available in two sizes: a 3.5 lb model, and a larger 5.5 lb model. Since both are very lightweight, and there’s very little difference in the price, we’ve selected the larger of the two for this list. Even though it’s bigger, it’s still light and compact, which makes it ideal for kayakers, SUP users, and inflatable boaters.

This anchor has a well-engineered 4-fluke design that can fold down for easy storage. It’s easy to deploy, and the sturdy prongs have no trouble finding purchase on almost every type of surface, including mud, rock, gravel, and sand. The anchor is made from tough mild steel that has been coated to protect the anchor from corrosion and rust but also to protect the side of your boat from scratches.

Each anchor ships with 25 feet of durable, marine-grade rope, an inline-buoy, and a huge stainless steel snap hook for easy deployment and tie-ups. The Airhead folding grapnel anchor also comes with a useful Nylon storage bag that has a padded lining to dampen any clanking sounds from your anchor when it’s in storage.

All in all, this is a great anchor for kayakers, SUP paddlers, and inflatable rafters. It will work fine with some larger boats too, however, we recommend that you only use with smaller watercraft or use it in tandem with another anchor if you want to use it on a larger vessel.

  • Anchor Type: Grapnel anchor
  • Anchor Dimensions: 13.63” long and 6.75” wide

This plow anchor is made from galvanized manganese steel. The plow design allows it to easily find purchase in the seafloor, giving you a strong and confidence-inspiring hold. It’s easy to deploy, and thanks to the shape, it’s very easy to pull up too.

Thanks to the use of high-grade materials and intelligent design, many boaters opt for this anchor rather than splashing out on a more expensive stainless steel product instead. In fact, this anchor has so many positive reviews that it’s hard to understand why anyone would pay more for something when this one does the job for a smaller price tag.

Installed correctly, and with a decent amount of chain attached, this galvanized anchor will have enough strength to hold boats that weigh more than 7,000 lbs in place—even in the most challenging of conditions. Some sailors have even reported a strong and tight anchoring position even in swells above 5 feet in height.

Lewmar’s Galvanized Delta Anchor is available in three different sizes: 14 lbs, 22 lbs, and 35 lbs.

5. SeaSense Slip Ring Fluke Anchor

Buy now

The SeaSense slip-ring fluke-style anchor is another budget-friendly product that offers impressive performance at an affordable price. It’s a simple fluke anchor that can hold your boat in place, even in stronger currents. That’s providing that you’re piloting a lightweight boat of up to 24 feet in length, and not at the helm of an oil tanker.

As anchors go, this one is relatively compact and very lightweight. It’s manufactured from magnesium and aluminum, with galvanized features. All of the materials are corrosion and rust-resistant, which is ideal for saltwater applications. The anchor has a slip ring, which allows for easier retrieval in case of snagged flukes, and sharp sturdy flukes that can anchor in anything.

The flukes are designed with a sharp angle, to help find purchase in a wide range of conditions. While it’s better in rockier conditions, it can grab easily in sad and muddy bottoms. Rocks are this anchor’s favorite, but since it’s still a cheap product, we recommend that you take care when dropping it and retrieving it, since those flukes can bend if too much force is applied.

Ideal in depths of over 40 feet, this anchor is a cheap and cheerful product that won’t let you down providing that you aren’t expecting too much from it. For the best results, users recommend it in conjunction with a length of chain between the slip ring and anchor line.

Features:

  • Anchor Type: Fluke anchor
  • Anchor Dimensions: 23” long 13.5” wide
  • Anchor Weight: 9 lbs
  • Material: Aluminum and magnesium

Frequently Asked Questions (FAQs)

1. How to anchor a boat? 

At first, you need to determine the water depth at the location of anchoring. Then, calculate the scope. Lower the anchor, while letting out plenty of scopes and securing the rope to bow cleat. Make sure there is no drag, and you are good to go.

2. What kind of boat anchor do I need?

This depends on quite a lot of factors. For instance, you need to determine the weather conditions, bottom conditions, and the location of your usual cruises. The anchor most suitable for these factors is the one you need.

3. How heavy should my boat anchor be?

You should first determine the weight of your boat and the bottom conditions in which you will be anchoring. The weight range that will work best with these factors is the one you should go for.

4. How does boat anchor work?

When the anchor penetrates the sea bottom surface, a suction is created. This produces resistance, which is created by the surface material along with the weight of the tool. Additional resistance is created as the anchor digs in deeper.

5. Can I anchor my boat anywhere?

Sadly, the answer is no. Some locations have restricted anchoring, while it’s just unsafe to leave your boat unattended for a while in some other places.

6. How to keep anchor rope from tangling?

For that, you would have to decrease the wire rope length and the amount of load lifted. Increasing sheave size also helps the cause.


Final thoughts:

There are many factors included when opting for Anchors, but there is no single Anchor to suit all needs. Different watercraft call for various anchors. Different customers have different and unique requirements. As well as various conditions demand different building materials as well as deployment approaches. A pontoon watercraft will have completely different support requirements to a luxury yacht, a casual paddler won’t need the same support as a deep-sea fisherman, and a river anchor isn’t going to quit on the ocean.

Nevertheless, if we had to pick extraordinary versions from our checklist that have exceptional top qualities, after that here are our faves or cream of the crop. What’s the best boat anchor out there? Before selecting one, understand what you are expecting and opt for the one that best suits your needs.
