If you plan to plant your vessel in coral, grass, or mud, you need to make sure you have the right type of anchor. You also need to consider how large your boat is and whether your anchor will support the boat’s weight without damaging it.
When looking for an anchor, you will see that there are many types of anchors with different designs, materials, shapes, and purposes. Many people believe it is important to have at least two anchors if not more. Here are a few tips  on what to look for in the best anchor for boats and a few reviews to help you start your search.

Anchors for Boats Buying Guide – Choosing the Right Anchor


What is the best type of anchor for my boat?

The best answer to this question is that most experts agree a boat needs more than one type of anchor on board. Depending on the type of bottom you are setting your anchor in, i.e. rock, coral, sand, grass, or mud. That will tell you which of the anchors to use. You also need to consider the state of the sea and the wind conditions when you are out on the water as well as the windage and size of the boat you are using.

Types of Anchors

There are two anchor styles that are the most common, the plow and the fluke. However, if you have a small boat and are using it on protected inland waters, you should use the inland type.
The fluke anchor is the most popular type and is commonly used as the only anchor on smaller boats. It is lightweight, holds well in both sand and mud, and stows flat. It has a great holding-power-to-weight ratio so you can actually use a lighter weight anchor in comparison to other types. It won’t hold in rocky or grass surfaces because its stock and flukes tend to foul on the anchor rode.

Plow and Scoop anchors are the best option if you will be using it in varying bottom conditions. They tend to be easier to rest if the current or wind changes direction. The scoop design features round “roll bars” that will self-right the anchor turning it the right way up automatically. Both of these anchors are very effective in sand, mud, and grass but they do not use projecting flukes that easily foul and their shape makes stowing them more difficult. They are often used as primary anchors on cruising sailboats and heavier powerboats.

Anchor Styles

Boating experts agree that for security reasons, you should carry two different boat anchor types, preferably the plow/scoop anchor and a Danforth style anchor. The different anchor types and uses you end up using will be dictated by the type of bottom you are setting the anchor in whether its rock, coral, sand, grass, or mud. Some situations may even require using more than one anchor at the same time depending on the windage, the boat size, seat state, and wind conditions.
When using two anchors, you may need to have one at the stern and one at the bow of the boat to limit how much the boat is able to swing. Setting two anchors from the bow at a 60-degree angle is another way to decrease the boats ability to drag and swing, plus it allows you to use less scope and to shorten the rodes. Also, you may not have enough holding power in heavy weather conditions with just one anchor and having a second anchor could be vital to your staying where you are. When the wind speed doubles, the actual force on a boat increases by four times.
Anchor Shapes

Weight Anchor – This anchor holds well because of its weight. This category includes older anchor shapes including the classic pole anchor and the heavy stone anchor.

Patent Anchor – Burrowing into the ground with their anchor chain and flunk, these anchors get their holding power. This category includes the plowshare anchor, the Danforth anchor, the Bruce anchor, the bow anchor, the plate anchor, and the plow anchor.

Mushroom Anchor – This anchor is used if navigation or lightship signs need to be fastened for a long period of time.

Four or Six Armed Draggen – This anchor is perfect for fishing in the Mediterranean.

Sand Anchor – With a spiral-shaped tip, this anchor is either screwed into the sand on the seabed or on the banks which is the only way they will work.

Weight Range

When considering the weight range needed for an anchor, you need to think about the weather you will be anchoring in, the locations, and the right size anchor for your boat. Check the manufacturer’s suggested sizes and also consider what your boating style is. Many people do like to follow the bigger the anchor is the better idea, but if you are drifting towards shore and you can’t raise the anchor with power, you need a light and efficient anchor that you can raise by hand.

Holding Power

What size anchor do i need? Is a common question that tends to be asked by new boaters. Holding power is a vital consideration when choosing an anchor, and it can have very little to do with the anchor’s weight and size. As the anchor penetrates the seabed surface, suction is created coupled with the weight of the anchor generates resistance. In the case of a coral or rocky bottom where an anchor can’t dig in, the anchor must rely on snagging on protrusions for a precariously hold.
With the ability to hold between 10 and 200 times the weight of itself, today’s anchors have amazing holding power. For example, a five-pound anchor can hold over 1,000 pounds.

Anchor Guide by

Instead of looking at the actual anchor weight you should look at it’s holding power rating. The amount of holding power depends on the weather conditions. The amount of holding power a boat can range from a few hundred pounds on a calm day up to 10 X that on a stormy day.

Bottom Conditions

In order to withstand the waves and wind, anchors need to create enough resistance in the seabed. This resistance is completely dependent on how it is able to penetrate and engage the seabed. Choosing the right seabed to set in is as important as how the anchor is designed. So, as you choose the design of the anchor always keep in mind the expected bottom condition as you shop.
Sand – Easy to anchors to penetrate, fine-grained sand will give you repeatable results due to its consistently high holding power. Hard sand will give most anchors the greatest tension with the non-hinged scoop anchor and the pivoting-fluke anchor are the best types of anchors to use in sand.

Mud – With low shear strength, mud needs an anchor design with a broader fluke or shank angle and larger fluke area while allows the anchor to dig into the mud deeper giving it more sheer strength. Sometimes, mud is only a thin layer over another type of material so if you have an anchor that can dig through the mud into the material underneath, it will hold more securely.

Coral and Rock – Your holding power is more dependent on where you set your anchor than on the type of anchor you have. In coral and rock bottoms, a grapnel-type or plow-shaped anchor is usually the best.

Grassy, Clay, or Shale – These types of bottoms can be the most challenging for whatever style anchor you have. If you are setting in this type of seabed, pay more attention to the weight of the anchor than the style for good holding power and penetration. Keep in mind that this type of seabed has a higher chance of a false setting since the anchor can catch on protrusions and roots instead of something solid.


Anchors come in one of three materials: lightweight aluminum magnesium, Grade 316 stainless steel, or galvanized steel. In terms of cost, galvanized anchors are the most affordable, plus they have the highest tensile strength. If you are looking to dress up your vessel’s bow, stainless anchors often look like works of art. But if you are more interested in the weight you are holding in the bow, you should go with aluminum-magnesium.
