Which Type Of Anchor Should Be Used Only For Small Lightweight Boats?

A lot of boat owners are looking for the most suitable anchor for smaller and lightweight vessels, and you’re probably one of them since you land on this post. This article seeks to address this topic, and without wasting time let’s outline them for you.

Which Type Of Anchor Should Be Used Only For Small, Lightweight Boats?

Which Type Of Anchor Should Be Used Only For Small Lightweight Boats?

  1. The Mushroom Anchor

This kind of anchor is made specifically for lightweight boats. How these anchor works are that, as it is dropped, it goes straight down to the sea bed and becomes buried in the muddy or wet soil.

This type of anchor is only meant for small vessels, and in no instance should they be used with larger vessels. That is a disaster waiting to happen because it is a very wrong match. A sailboat is too big for this type of anchor, except it’s a smaller one.

The Mushroom anchor is named after its shape, that is, the shape of a mushroom, and it is quite very light in weight. It is not suitable for tough weather conditions. Another reason why mushroom anchors are a bad fit for bigger vessels is that, instead of grabbing or clenching at the seafloor, they just sink in and get buried. They are best used on lakes where the wind resistance is relatively low, and they can only be used for short periods of time.

  1. The Danforth Anchor

This type of anchor is also called a Fluke. Anchors like these are made specifically for lightweight vessels with a range that starts from 3 livres to as much as 180 livres. They are often paired with vessels that are used for recreation. This is because, in comparison to the holding power they possess, their weight is quite light.

How they function is that they sink down into the ocean bed and dig. They are most effective on muddy or fairly hard ground. But, they are not to be used in extremely soft or loose muddy ocean floors. Those could clog up the flukes. Neither are they to be used on rocky floors where it will be difficult for them to grab onto something and hold fast. Flukes cannot also grab onto grassy ocean floors, so do not use them in such cases.

  1. A Grapnel Anchor.

This is a very common anchor that is used by most fishermen. Also, with boats like canoes, and kayaks, and other small crafts, the grapnel anchor is usually utilized. They are quite compact for stowing.

They function by hooking onto materials such as a large boulder or a rock and they hold quite fast. Due to their ability to hold fast and firm, it could be tough sometimes, getting them out of places they have anchored to.

  1. The Kedge anchor.

These are commonly used with yachts. They function by sharply turning the kedgen, which is the anchor, for either fast or slow mooring. They are best used in lakes or rivers with grassy bottoms.

  1. The Northill anchor

This compact anchor, made initially for seaplanes, consisting entirely of stainless steel, is easily transportable in your smaller vessels.

Before undertaking any voyage, selecting the right anchor to take along is usually an important part of the planning process. This is quite needful, in case of any emergencies or hazardous situations.

Below are some factors to take note of when choosing the right anchor to take on a voyage, with respect to your boat type.

  1. The anchor’s weight

The heavier it is the better. This is because the heavyweight is advantageous in turbulent situations, to hold down the boat and keep it from being tossed about, or from drifting off. It is best to take at least two types of anchors whenever you go on a voyage.

This is to proactively prepare for whatever you may face. In calmer conditions, a lightweight anchor such as the “lunch hook” would be a good fit. But in windy conditions or for all-night voyages, a bigger anchor is recommended.

  1. The anchors make

What an anchor is made of, should also be considered in your choice of what type of anchor to use with your boat.  Most anchors have galvanized steel as their main constituent, to prevent rust. An anchor of choice should not have more than 0.2 percent of the carbon in its make.

Flukes should be made of mild steel, as per required standard, while shanks should be made of constructional steel with a significant amount of manganese, or anything other metal that follows the high strength low-alloy requirement.

For maximum durability, anchors made of either steel (stainless) or aluminum, need a very conscientious amount of alloying or should be designed skillfully. As a result of these procedures carried out on such anchors, they tend to be expensive.

Anchors made with these materials are quite durable, but anchors made from aluminum do not function as well as those made of steel, although both are rust-resistant.

Kedge anchors are often made with aluminum because of their relatively lightweight.

  1. The ability of an anchor to hold fast.

As wise as it is to go for an anchor that is a perfect fit with your type of vessel, it is also wise to consider the holding power of that anchor. What is its probability of holding up under intense weather conditions?

There is a way to determine the holding power of your anchor of choice, although this factor is relative to the type of weather you’re going to face. But, by the rule of thumb, if your vessel is at least twenty feet long, then an anchor of about 95 holding power is suitable to secure your vessel in windy conditions of up to 20 miles per hour.

For a vessel 30 feet long, under the same weather conditions as described above, then, an anchor with a holding capacity of 130 is a better match.

Lightweight anchors can only hold up vessels that are roughly twice their weight. That is why it is not only the make or craftsmanship of a vessel that should be taken into consideration before purchase. An important factor, such as the type of anchor that will be suitable for it, should also be taken into consideration. A mismatched anchor will always lead to anchor dragging.

  1. How sharp the anchor’s tip is.

For an anchor to instantly grab onto or dig into the ocean floor, its tip has to be quite sharp. New anchors are honing in on this factor. Anchor manufacturers, both the new age and a few of the old have decided to hone in on this factor by making anchors that have heavier lead or steel tips, and also, have decided to reduce the weight of the other parts of the anchors, such as the fluke and shank.

In casting an anchor, only the tip and the outer edge of the shank have contact with the ground. Upon reaching the ocean floor, the fluke and shank combined to form an angle that gives way for optimal penetration. This angle is usually roughly 35 degrees.

  1. Condition of the ocean floor

The bottom of the ocean also plays an important role in determining the type of anchor you should consider having aboard. The condition of the ocean floor will determine how effective your anchor will be at grabbing onto materials or digging into the soil.

Here is a list of anchors with their corresponding suitable ocean floors.

  • – Plough anchors (without hinges) and fluke anchors are best used with sandy ocean floors
  • – Also, fluke anchors that have a wider shank are very effective with muddy ocean floors to dig in and hold fast.
  • – Grapnel or plough anchors that have a high holding power could be used for rocky ocean floors.
  • – Anchors with a sharp tip, such as the scoop anchors are good for clayey ocean floors
  • – Plough anchors with sharp tips are effective with grassy ocean floors.

In peculiar cases, you might need a special type of anchor and also when the ocean floor over which you’re navigating is different from expectations. If you’re confused about deciding on the type of anchor to use with your vessel, then you should consider asking those who are very experienced in such matters.

If you plan on making a voyage to an unfamiliar location that you have not visited before, it is best to check out online boating forums, to get more information about the condition of that sailing route.
