Description: Developed in the late 19th century, stockless anchors represented the first significant departure in anchor design in centuries. Though their holding-power-to-weight ratio is significantly lower than admiralty pattern anchors, their ease of handling and stowage aboard large ships led to almost universal adoption. In contrast to the elaborate stowage procedures for earlier anchors, stockless anchors are simply hauled up until they rest with the shank inside the hawse pipes, and the flukes against the hull (or inside a recess in the hull).
While there are numerous variations, stockless anchors consist of a set of heavy flukes connected by a pivot or ball and socket joint to a shank. Cast into the crown of the anchor is a set of tripping palms, projections that drag on the bottom, forcing the main flukes to dig in.
Until now, there are many different types of stockless anchor in the market, United States Navy (USN) type, Japan (JIS) type, Hall type, AC-14 type, Speck type, Byre type,etc.

Mushroom Anchor
HS Code: 7316000000
IMPA Code: None
Location: China
Categories: Ship anchor
Export: America, Euro, UAE, Japan, Korea, Worldwide
Description: For one hundred forty years, harbormasters have relied on mushroom anchors for permanent moorings. The mushroom anchor was invented by Robert Stevenson, for use by an 82-ton converted fishing boat, Pharos, which was used as a light vessel between 1807 and 1810 near to Bell Rock whilst the lighthouse was being constructed. It was equipped with a 1.5-ton example.
It is shaped like an inverted mushroom, the head becoming buried in the silt. A counterweight is often provided at the other end of the shank to lay it down before it becomes buried.
A mushroom anchor will normally sink in the silt to the point where it has displaced its own weight in bottom material, thus greatly increasing its holding power. These anchors are only suitable for a silt or mud bottom, since they rely upon suction and cohesion of the bottom material, which rocky or coarse sand bottoms lack. The holding power of this anchor is at best about twice its weight until it becomes buried, when it can be as much as ten times its weight. They are available in sizes from about 10 lb up to several tons. A mushroom anchor is excellent for permanent moorings, channel buoys, and other navigation aids. This style takes firm hold and remains fixed under adverse conditions, as it oscillates under strain it buries itself deeper.

Stainless Claw Type Anchor
HS Code: 7316000000
IMPA Code: None
Location: China
Categories: Ship anchor
Export: America, Euro, UAE, Japan, Korea, Worldwide
Description: This claw-shaped anchor was designed by Peter Bruce from the Isle of Man in the 1970s.Bruce gained his early reputation from the production of large-scale commercial anchors for ships and fixed installations such as oil rigs. The Bruce and its copies, known generically as "claws", have become a popular option for small boaters. It was intended to address some of the problems of the only general-purpose option then available, the plough. Claw-types set quickly in most sea beds and although not an articulated design, they have the reputation of not breaking out with tide or wind changes, instead slowly turning in the bottom to align with the force.
Claw types have difficulty penetrating weedy bottoms and grass. They offer a fairly low holding-power-to-weight ratio and generally have to be oversized to compete with other types. On the other hand they perform relatively well with low rode scopes and set fairly reliably. They cannot be used with hawse pipes.

Lightweight Anchor
HS Code: 7316000000
IMPA Code: None
Location: China
Categories: Ship anchor
Export: America, Euro, UAE, Japan, Korea, Worldwide
Description: This streamlined, superior-holding-power LWT anchor affords a 25% weight reduction over conventional stockless anchors. The lightweight anchor is widely used and is well known for its good holding in sand and clay bottoms.
The light weight anchor is cheaper and easier to handle, but they have limitations: Sheer weight helps an anchor dig into the sea bottom and quickly set itself firmly in place. In fact, many conservative boaters insist that any anchor weighing less than 30 pounds (14 kg) has no place on a boat. That may be true when anchoring in hard sand or on a bottom covered with dense weed or thick grass, because it will be difficult for a light anchor to break through to the ground—but it’s not the whole story. Lightweight anchors such as the Danforth, the Performance, and the Fortress have no peers when it comes to anchoring in mud or soft sand and clay. Their large fluke areas generate tremendous resistance to being pulled through soft bottoms. Their superior performance depends on their being able to dig into the holding ground in the first place, of course, which doesn’t always happen. If that were guaranteed, they would be the perfect anchors. There would be no need for the heavier plows, which—although their holding power is less—will set in anchorages where lightweight anchors are useless. All light anchors are carefully constructed so that the angle their flukes make with the shank is carefully controlled for optimum penetration and holding power. Some have flukes whose angle you can alter so they open farther— the better to deal with soft mud. Despite their light weight, these anchors have to be exceptionally strong to endure the strains imposed by high winds and swells. Unfortunately, their strength doesn’t always match their holding power. Always choose the type made from high-tensile steel.

Danforth Anchor
HS Code: 7316000000
IMPA Code: None
Location: China
Categories: Ship anchor
Export: America, Euro, UAE, Japan, Korea, Worldwide
Description: American Richard Danforth invented the Danforth pattern in the 1940s for use aboard landing craft. It uses a stock at the crown to which two large flat triangular flukes are attached. The stock is hinged so the flukes can orient toward the bottom (and on some designs may be adjusted for an optimal angle depending on the bottom type). Tripping palms at the crown act to tip the flukes into the seabed. The design is a burying variety, and once well set can develop high resistance. Its light weight and compact flat design make it easy to retrieve and relatively easy to store; some anchor rollers and hawsepipes can accommodate a fluke-style anchor.
The fluke anchor has difficulty penetrating kelp- and weed-covered bottoms, as well as rocky and particularly hard sand or clay bottoms. If there is much current, or the vessel is moving while dropping the anchor, it may "kite" or "skate" over the bottom due to the large fluke area acting as a sail or wing. Once set, the anchor tends to break out and reset when the direction of force changes dramatically, such as with the changing tide, and on some occasions it might not reset but instead drag.

Pool N Anchor
HS Code: 7316000000
IMPA Code: None
Location: China
Categories: Ship anchor
Export: America, Euro, UAE, Japan, Korea, Worldwide
Description: The POOL N anchor is said to be the most beautiful anchor. Probably for this reason large yachts and cruise vessels are often equipped with this type of POOL anchor. This does not mean that these anchors are not in use on board of cargo carriers. On the contrary, some of the biggest container in the world equip all their vessels with this type of POOL anchor.The flukes of the POOL N anchor are constructed out of two shaped plates, which are welded together. Therefore, the flukes of the POOL N anchor are hollow. This construction gives the anchor a large resistance against bending forces. These Anchors are fully balanced, which enable them to be smoothly stowed in an anchor pocket. The end shape of the shank of the anchor can be varied for application of all different types and dimensions of connection parts. Allthough all POOL anchors have high holding ability, the POOL TW anchor shows best the combination of holding power and fluke surface. The anchor has large flat flukes made out of high tensile steel plate material. The thickness varies from 15mm up to 140mm (depending on the anchor size).The extreme points and the inner edges of the flukes are sharpened in order to enable them to dig easily. To prevent the anchor from digging in to deep, the POOL TW anchor is equipped with crown plates. The end shape of the shank of the POOL TW anchor can be varied for application of all different types and dimensions of connection.

Deadweight Anchor
HS Code: 7316000000
IMPA Code: None
Location: China
Categories: Ship anchor
Export: America, Euro, UAE, Japan, Korea, Worldwide
Description: This is an anchor which relies solely on being a heavy weight. It is usually just a large block of concrete or stone at the end of the chain. Its holding power is defined by its weight underwater (i.e. taking its buoyancy into account) regardless of the type of seabed, although suction can increase this if it becomes buried. Consequently deadweight anchors are used where mushroom anchors are unsuitable, for example in rock, gravel or coarse sand. An advantage of a deadweight anchor over a mushroom is that if it does become dragged, then it continues to provide its original holding force. The disadvantage of using deadweight anchors in conditions where a mushroom anchor could be used is that it needs to be around ten times the weight of the equivalent mushroom anchor.
