The generally accepted approach is that the adhesion capacity of iron is directly proportional to its weight. While this is generally true, there are some exceptions. For platforms used in oil exploration and extraction in the North Sea, which is most thought about iron and vault technology, research on irons and adhesion methods based on harsh natural conditions factor, for example, depending on the weight of the adhesive is not possible to say. It is possible to maintain a very superior adhesion by burying a giant steel plate with a very large surface according to its weight on the sand floor.  Therefore, many boat owners or captains have spare irons of different types and models than the iron they use mainly for use in different situations.


Double-fingered-Eye iron

It is mostly used in very large sizes (75 kg and above) on commercial ships or high-tonnage yachts, or in small sizes in small boats or axles. The sizesized ones used on ships are also called eye iron.

The sizes used in yachts are usually constructed as castings and must be painted frequently to prevent corrosion. It does not have a high adhesion capacity due to blunt nails, it adheres more with its weight. Those in the market are usually poured from poor quality metal, reported to be broken under high power.

Four-fingered anchor

Since it takes up a lot of space on the boat, models with folding arms are usually preferred. These are also known as umbrella irons. It is a type of iron that is easy to hide and clings to thanks to triangular nails at the end of the four. Mud and sand are more efficient on the ground, but less reliable, and are rarely used as the main iron in medium and above travel yachts. When folded, it takes up little space in the boat. The smaller ones are used as hooks to catch free chains and ropes that are attached or fallen at the bottom. Under normal conditions, it is easy to discard and collect. It is preferred in small boats and wildcards, and stainless ones are often used for this job because the rust stain is difficult to get out of both PVC and other bot fabrics. It's cheap iron.

Large models that do not fold are not suitable for sailing boats. He uses the heavy and large ones as vault iron. Angling uses small types of them on their heads. {{-}}

Fishing iron (Admiralti)

It is one of the most widely used types of iron in the world. It consists of a handle or body (4), chipo (2), arms (6), nails (5) and lock or mother (1). The folding of the chipo and arms makes it easy to move. Although cumbersome on the hand and deck, it is actively held on the bottom, on floors such as noodles or gravel, thanks to its triangular or diamond (Hereshoff) shaped nails and cross chipo.

Compared to other irons, it should be heavier for the same adhesion rate. It is widely used on our southern shores in boats such as gulet and tirhandil, it is mostly used as spare iron because it is difficult to carry on the front side of mass-produced yachts, models that can be completely disassembled or folded are very suitable for this purpose. It is usually carried by hanging the iron from its body without taking it completely onboard. It is necessary to keep in mind that this type of transport requires a separate experience and can give anchors in seay weather.

An important flaw of the fishing iron is that while one arm is buried on the ground, the other arm and fingernail remain outside, and especially when the boat is left on the alarga, the boat rotates around the iron, and the chain is wrapped around the outside arm. This entanglement can also occur in cases where iron is thrown quickly and by putting the chain wide and empty and prevents the iron from holding, which is one of the reasons why many boat captains on our southern shores are landon the stern.

PloughIron-CQR (Lewmar)

Designed by British mathematician Geoffrey Ingram Taylor for use in seaplane palamars, this anchor was used by many yachtsmen for many years as the main anchor of the boat. Derived from the english word "secure" or "secure", the Scottish production Plough Iron, which is widely known as CQR, is still sold by Lewmar. Even if his arm lies sideways, it has a plough form that allows it to get stuck on the sea floor, which he takes his name from. The fingernail is produced more heavier than its body. It provides good grip on all types of sea floor except hard floors and rock. It is used as the head iron on many travel yachts. He sits comfortably in his nest, doesn't give us a hoe. Thanks to the joint in his elbow, it does not immediately get rid of where it is holding when the direction changes, and even if it scans, it provides active adhesion again. However, it is not preferred for redundant iron in the stern or elsewhere, it is relatively difficult to carry by hand due to the joint, which can cause injury and compression of the fingers if not taken care of. The price is quite expensive compared to their counterparts.


Patented by American designer Richard Danforth in 1948, this iron ensures effective adhesion on the sand floor thanks to the 32°degree angle made by the large nails with the body. Thanks to the large side bar that first comes into contact with the floor, one of the symmetrical surfaces falls on it, and when the shot continues, the nails are buried at the bottom. It is particularly successful in the sand, but noodles often scan on the floors. It's hard to hold on again if it scans. Excluding fortress and other aluminium alloy anchors, it has the widest rate of quotations depending on its weight. Therefore. Being light is an important advantage. It is especially ideal for carrying wildcards by boat because it does not take up much space, and is also used as a stern iron. In the slot where it is placed as a head iron, it is common for the large bar to anchor around during boat manoeuvres. Therefore, the bar is either never before or kept too short, similar ones are derived and widespread. (See Chapter 11) Britany, FOB)


It is a similar model developed by Danfort. The only difference is that it is made of aluminium, a much lighter alloy than forged steel. In this way, iron with the largest nails according to weight. The sand holds safely on the ground, it is possible to change the nail-torso angle to 42 degrees for more effective adhesion on the slime floor. It can be stored by disassembling pieces attached to each other by steel bolts, thus taking up less space on the boat. Thanks to its lightweight, it is ideal for hand-throwing and pulling. It is used safely as astern iron in small cruise boats without irgat, and is preferred for this reason in racing boats. Under great powers, it has been reported that the nails are bent, and should not be forced too hard when inserted.

Guardian iron is also preferred because it is slightly cheaper in shape, material and performance compared to Fortress in many respects.


It was one of the first generation anchors introduced by Peter Bruce in the 1970s. Also known as duck anchor. It is famous for maintaining grip at a shorter distance and being able to rotate 360 degrees without getting rid of where it is holding. It is used by yachts roaming coral, rock and sand-based South Pacific, but does not have the same activity on common noodleand reed floors in the Mediterranean. In chains, it can give anchors, is not preferred as a stern iron, but it is carried comfortably in the nest on the nose of the boat, remains constant after sitting down, does not play with swings. It is produced in a relatively cheap way thanks to its production of hot galvanized solid steel and is a solid and reliable iron. Imitations are available on the market.

Delta (Lewmar)

Also known as triangular iron. Launched by Simpson-Lawrence in the early 1990s, Delta is considered the first of a new generation of anchors. Unlike cqr, the plow-style nail is fixed to the body. The tip of the nail is aggravated to increase the effectiveness of the stud. In this way, it is lodged in the ground more effectively in a short time. It is easier to carry by hand because it has no joints and is much cheaper to manufacture than CQR. It is one of the most widely used anchors.

Cobra (Plastimo)

This anchor, which is very similar to Delta in shape with its jointless arm and plow type adhesion surface, can also be used as a replacement iron thanks to its arm being disassembled. In the Cobra 2 model, a stronger mount was developed for this joint. Together with Delta, the new generation of anchors are the most advantageous in terms of price.

Spade (Blue Water Supplies)

Designed by Alain Poiraud in the mid-1990s, it is one of the next generation anchors. Unlike other plow types, there is a concave adhesion surface. It is sharp and the tip is stuck on the ground quickly and effectively with its aggravated and reinforced fingernail. It has been found that such concave nails can be buried deeper than the plowones. As the floor descends towards the lower layers, it is denser and therefore provides a more effective adhesion.

It is named after the initials Société de Production d'Acastillage et Divers Equipement of the French. The handle can be disassembled, the yellow body color is easily noticed from the surface even in deep waters. Especially in heavier models (more than 80), in order not to disturb the weight distribution, the hollow-made handle is much lighter than the body, disassembled and provided ease of storage. The handle is attached to the body by a bolt, but it is not burdened when it is under power. It is made of galvanized steel (S series), stainless steel (X series) or aluminium alloy (A series).

Britany (Plastimo)

Although the shape resembles the original Danfort, it is evident in the absence of the long side bar. In this way, it is widely used as the head iron, but may not fall on both fingernails immediately, like the similar ones while sitting at the bottom. Made from galvanize, it provides effective adhesion on soft floors with large and symmetrical nails. It is also suitable for use as aft iron.

FOB (Calibra)

This French-made iron is very similar to Danforta, the basic separation is hollow square metal that can be used to hold the hand in the head. This stem, which facilitates hand-to-hand handling, is thought to increase sand.. Unlike Britany, a balance bar stands out that prevents it from falling sideways, but not as long as danfort and fortress. Galvanized (FOB THP) and aluminium are made, especially the lightweight FOB Light is ideal for hand-to-pull and use butt iron.

Buegel (Wasi)

It was made in Germany in 1986. It takes its name from the "stem", which is the most remarkable feature of iron. When it falls on the ground, it is easily carried by hand thanks to this semi-circular handle, which allows the adhesion surface to touch the ground by rolling over it. It has a single fingernail with a flat form that is different from plows or concave alternatives. When the big semicircle in his head sits in the rod head slot, he can create a anchor with a varicose vein and a borda lantern.

It was designed by the steel company Wasi especially for Mediterranean waters rich in noodles and reeds. It is produced as stainless or galvanized, it is a simple, relatively inexpensive, reliable anchor, but it is common to imitate on the market.

Supreme (Manson)

Another new generation anchor of New Zealand origin that stands out relatively little in our waters. To save the anchor when attached to the bottom, it is easily distinguished from the others by its long groove along its length, its distinctive, lightened handle and a semi-circular bar, as in Bugel. It is also thought that there is no need for rescue rope detection and that wind changes can cause relief from the ground in geographies where sudden and almost 180º. Thanks to its sharpened and aggravated end, it is quickly and effectively lodged in the ground, and thanks to its concave nail, it has a high adhesion capacity on all types of floors.


It was designed by the famous New Zealand sailor Peter Smith and was released in the early 2000s. The handle part of this anchor, which is made of galvanized steel which is quite large according to its weight, concave, which can hold on any ground thanks to its single fingernail, is reinforced, easily sits in the slot at the head thanks to its angle with nails and does not dislodge in the shakes. The semicircular bar can create a chawea with a circle (boron lighthouse, vardavela, etc.) while in the slot at the head.

Ultra (Size Machine)

It is an advanced iron developed by Turkish engineers and made of advanced technology. The lack of a semicircular bar on the side of the head is one of the most important advantages. The concave adhesion surface features a large single nail that is weighted downwards and aggravated by its sharpened tip. Thanks to the strong but lightened (hollow) handle that makes the right angle with the nail, it can easily sit in the socket and stand safely in the shaking, always come symmetrically to the nest when coming out of the bottom thanks to its suitable hydrodinamia, and always on top of the fingernail when going to the bottom. reduces use. The disadvantage is that it cannot be mass-produced from galvanization, but its technology is more expensive than its counterparts because it is available to manufacture by hand and made of stainless steel.

Apart from these types, there are many different types and models of irons that are not seen in our country such as Barnacle, Bulwagga, XYZ, Oceanie, Northill, Sarca, Brake, HydroBubble.
