The Mantus Anchor is a “heavy-duty sea anchor” capable of holding boats up to six tonnes (13,228 lbs). It’s a versatile anchor that can be used to stabilize boats for maneuvering in rough weather conditions, or as a permanent type anchor.

The Mantus sea anchor comes is easy to use. When assembling, the anchor and anchor drop weight attach to the rope using a heavy duty shock-cord. Then, the floation tube is inflated using the built in foot pump for a hassle-free and fast assembly.

Frequently Asked Questions (FAQ)

What is the best boat anchor to buy?

For boats up to and including 20 feet, boat anchors should be of a size and strength to hold the boat in place in the anticipated conditions. It is most likely that even a small boat will have a bow anchor, plow anchor, and two anchors…. However, if your boat is longer or you are planning to live aboard it, carrying a larger anchor is probably in your best interest.

Even boats of 10’ or smaller still need a bow anchor or plow anchor. These anchors are obtainable in different shapes, sizes, and capacities.

What is the best type of anchor?

Caves below the Canaries are so vast that mapmakers can't name them all. Almost every island is encompassed by a system of interconnected caves, and on many, there are amazing formations of rocks and arches, stalactites and stalagmites.

As well as the world's most beautiful cave systems, some of the clearest waters in the world can be found under the Canary Islands.

Due to the volcanic origin of the island, the seabed is sandy but full of sea plants so divers must dive carefully to avoid the fragile sea grass.

How do I choose the right size anchor?

Anchors are a constant source of confusion among boaters and the general public, so let's delve into the typical questions and help demystify the very simple science of anchors.

When it comes to anchor size, the leading factor should be the boat's weight. This includes the boat, trailer, fuel, and every single personal item on board. Use this total weight as the star size for your anchor charts.

The second factor you should consider is the type of bottom you will be anchoring on. Sand, mud, grass, coral, and the like are difficult to hold. This is especially true in tidal zones where the bottom changes rapidly. The key is to anchor deep enough, hence the star size and length of anchor chain.

What type of anchor is used for lakes?

If you are going to be boating on a lake, you should invest in one of two types of anchor. If you are going to be using a boat that is less than 12 feet long, an anchor sled is a perfect solution. This is a metal frame with a chain attachment. You attach the anchor where you want it and then use the sled to secure the chain.

If your boat is going to be bigger or heavier, however, you will want to go with a traditional anchor. There are several varieties of traditional anchors like Danforth anchors, mushroom anchors, and grass anchors, but in general, you will want to consider size first.

For boats heavier than 12 feet, you will want to invest in at least a 15-pounder – probably much more. Remember, the faster your boat sails, the larger your anchor should be.

Conclusion

This post will tell you what you need to look out for to find the best boat anchor for your next boat. There are many designs, sizes, and prices, but coming up with the right one isn’t so hard if you just pay attention to what you’ll be using it for. Will it be for anchoring in a current? Will it be for sea fishing, or do you need one for your small boat? Will you be anchoring at night, or only for the day? These are the kinds of questions you should be thinking about because you’re going to need to know how your anchor will be used.
