Anchor in brief
The anchor lies on the bottom and engages, and not only the anchor holds the yacht, but also the weight of the anchor chain. And this process is mutual - the anchor does not allow the chain to crawl, and the chain keeps the anchor pressed to the ground, helping it to cling to the solid and adds weight.
The anchor released from the vessel should lie on the bottom, turn over correctly and catch on the ground. The main parameters of the anchor are holding force, size and ease of storage. The higher the holding force, the less bulky the anchor you will carry with you. There is a universal rule for calculating the weight of an anchor, which is suitable for most types of anchors: - for every 100 kg of your boat's displacement - 1 kg of anchor weight.
Main types of anchors.
There are many types of anchors. But we will consider only the most popular and demanded ones, and also learn how to use them correctly.
Simple and compact the Mushroom anchor is one of the most popular options for inflatable boats. It takes up little space in the boat and has no moving parts. Often such anchors are covered with polymer paint, which protects the anchor from corrosion, and the boat hull from friction and scratches in contact with it.
The Mushroom anchor does not adhere well to rocky bottom and is not suitable for bodies of water with fast currents.
Tri-Fluke River Anchor ‘Chamomile’
The Chamomile River Anchor got its name from its petal design. It is convenient when used with a winch. This version of the anchor is more reliable and functional in comparison with the Mushroom one.
The River anchor finds its adhesion to the bottom much faster and more firmly, and it is stable on a body of water with the current. Thanks to these qualities, it received the name "River".
It is worth remembering that the River anchor is too tenacious. If such an anchor gets caught on a snag, it will be very difficult to pull it out.
Water Spike Anchor
The Panther Water Spike anchor
has original design, developed by professional anglers from the USA and Canada. It is considered one of the most tenacious and lightest when used on rivers and lakes. At the same time, a special ring allows to unanchor quickly, if it is necessary.
We recommend buying the Panther Water Spike anchor for owners of small boats with metal or plastic hulls looking for a lightweight and versatile anchor for all types of soil on rivers and lakes.
Anchor Cat (Grapnel Anchor)
The folding anchor Cat is considered the most popular model among inflatable boat owners. The universal legs of the Cat anchor
allow you not only to go deep into the sandy bottom, but also to cling to stones reliably.
The convenient folding design of the anchor is liked by its compactness when transported in a boat, therefore it competes well with other anchors. The folding anchor Cat is lightweight and is considered the best option for all types of boats, including inflatable rubber or PVC boats.
We recommend buying the Cat anchor for those who are looking for a very compact foldable anchor designed for inflatable rubber or PVC boats with rigid flooring, RIB boats or boats with a metal or plastic hull.
Minn Kota Shallow Water Anchor
World renowned trolling motor manufacturer Minn Kota offers shallow water anglers two innovative anchor systems, Minn Kota Talon and Minn Kota Raptor.
The Minn Kota Talon
and Minn Kota Raptor
shallow water anchors have a rod-type operation, i.e. with the help of a metal rod, they are stuck into the bottom of the reservoir, thereby, not allowing the boat to move from its place.
The Minn Kota Talon shallow water anchor mounts to the boat's transom and is electrically lowered vertically downwards in three steps and locks your boat at a given point with unparalleled strength and safety.
Minn Kota Raptor anchor is a new hydraulic anchor for shallow water with patented intelligent technology for analyzing the condition of the water and the bottom of the reservoir.
The Minn Kota Raptor continues to operate even after the boat is made fast in desired position to hold you more securely than any other anchor, especially in tough conditions. It knows where you anchored, what is happening to your boat and what to do next. Minn Kota's legendary durability and innovative anchorage technology make the Raptor the only hydraulic anchor that can call itself flawless.
We recommend buying the Minn Kota shallow water anchor to owners of fishing boats, those who are looking for the most accurate and reliable anchor for all types of bottom.
The Hall classic rodless anchor is a box with legs and a movable spindle. This anchor has a long history of operation in cargo ships.
The Hall anchor works equally well on pebble ground as well as in sand. Its weight of the head with legs, like other rodless anchors, makes up most of the total weight of the anchor. This is necessary in order to ensure the best possible immersion of the paws in the ground.
The relatively easy turning of the paws out of the ground is the main disadvantage of the Hall anchor. For reservoirs with a soft and loose bottom, such an anchor will not be reliable enough.
Danforth or Fluke Anchor
A modification of the Hall anchor is the Danforth one. Practice has shown that the closer the anchor legs are to each other, the better its sinking power. Therefore, with a lower dead weight, the Danforth anchor
holds better than the Hall one.
Danforth's transverse armature prevents it from toppling over. The anchor fits comfortably in the roller and is widely used with automatic winches.
The disadvantage of the anchor is its bulkiness. It is invisible in the hanging position on the roll, but when transported in an inflatable boat it will be obvious. It takes up a lot of space. It is impossible to shorten the anchor rod, since the anchor will immediately lose in chain force.
In 1986 yachtsman and engineer Don Gallerberg introduced the Fortress light anchor to the market.
Today "Fortress" is perhaps the most famous example of the entire family of Danforth anchors. Having adjustable legs, the "Fortress" anchor is made of aluminum, which makes it lightweight and durable (there is no welding, which can lead to breakage).
We recommend buying the Fortress anchor
for those who are looking for a reliable option for a boat or yacht equipped with an automatic winch, as well as for operation in a sandy or muddy reservoir.
CQR or Plow Anchor
The inventor of this most famous anchor in the world was the English mathematician Jeffrey Taylor, who called it CQR (Coastal Quick Release or Clyde Quick Release, later renamed "safe" by Lumar).
The single-leg plow anchor is excellent at handling various types of bottom soil. Such an anchor digs well into the soil of a muddy and sandy reservoir, where it can go well to a depth. But on a rocky bottom, such an anchor works much worse.
The anchor consists of a spindle and a single share-paw, which are connected by a hinge joint. This connection is designed to drop the anchor to the bottom in different ways. Even if the anchor falls to the bottom with the tip of the paw upward, then under the tension of the anchor rope it will surely turn over and go deeper into the ground.
The plow anchor works well with automatic winches and looks stylish on the roll of the boat. This anchor can be safely called one of the most common anchors in the world, which are used with small boats and boats.
The plow anchor is worth buying for those who are looking for a stable bottom grip option and for sailing enthusiasts.
Bruce or Claw Anchor
Bruce's anchor is rightfully considered one of the best rodless anchors. It has no moving parts, and its one-piece construction and flat paw with peculiar bends allows it to dig into the ground easily, even with a side fall.
Bruce's anchor is made of steel and aluminum, has almost the same holding strength, despite the different weights.
To choose Bruce's anchor according to the weight of the vessel, this table will help:
| Anchor weight (kg)
|| Length of the vessel (m)
We recommend buying Bruce's anchor for those who are looking for a reliable and sturdy version of an anchor for small vessels (launches, tugs, yachts, boats).
Delta or Wing Anchor
is an improved model of the CQR, characterized by the absence of a hinge connection - the foot and spindle are connected rigidly. The verified angle of their connection made it possible to make the ground grab faster and stronger. The strengths of this type of anchor are exceptional holding force on any bottom soil (including silt), quick recovery of traction when the ship's rotation causes the anchor to be pulled out and the ability to increase traction when the wind increases. A number of tests have confirmed that the Delta anchor
has the highest holding power in relation to its own weight. The Delta is inferior only to "new generation" anchors in holding power of all plow varieties. For the rest of the indicators, Delta is almost the same as CQR.
We recommend buying the Delta anchor to owners of a boat or yacht equipped with an automatic winch, looking for a beautiful and reliable version of an anchor for any bottom relief.
New generation anchors "Bugel", "Mantus", "Rocna", "Spade", "Vulcan".
These new varieties include the “Bugel”, “Mantus”, “Rocna”, “Spade”, “Vulcan” plow anchors. In terms of holding power, the "new generation" anchors have the best performance among all plow anchors. Their distinctive feature is the large mass of the tip.
For the "Spade" anchor, it, for example, makes up almost half of the total mass of the anchor.
"Bugel" has the simplest design - a rather short flat paw, flat spindle - which significantly reduces the cost of its production. However, in emergencies, the holding force of the "Bugel" may not be sufficient for a cruising yacht.
According to experienced skippers, "Rocna" is one of the best plow anchors. It picks up the soil quickly and holds the yacht well. A large yoke, which simultaneously acts as a rod, can be noted among the disadvantages. Due to this, the anchor takes up a lot of space on the yacht and is inconvenient for storage.
The Vulcan anchor is development of Rocna company, following the launch of the highly successful, internationally recognized Rocna anchor. The idea is to get the same legendary anchor holding power, but not have problems with anchor placement in the bow from behind the arc.
The Vulcan anchor design is suitable for a wide variety of sailing or motor yacht bow configurations. The Vulcan anchor offers the protection and reliability of a Rocna one with even better anchor hold on any soil.
We recommend buying a Rocna anchor to absolutely all owners of a boat or yacht equipped with an automatic winch, for use in any water body and with any type of bottom.
A drag or drifting anchor (parachute) is used to reduce the speed of drift or to keep the vessel with the bow towards the wind. The drag anchor eliminates the risk of toppling over when mooring a boat on leeward shore.
So, let's summarize. There are a variety of options for boat anchors. For most cases, the Mushroom, Chamomile or Cat anchor will do. The choice of anchor should be based on the dimensions of the vessel and the sailing area. For an inflatable boat of 3-4 meters, the recommended anchor weight will be 3-4 kg. For owners of large frame boats, launches or yachts, anchors are needed more serious and more powerful, since the coast in bad weather can easily turn into a serious problem.
