Before mentioning in detail about classification of anchors and the review of their design, it would be for a start quite good to understand for what in principle the anchor is necessary? The answer is quit simple – the anchor is urged to provide the steady parking of the vessel on raids and in the high sea with depths, available to it. But there is more to come: the anchor device is also irreplaceable during mooring in the conditions of the extremely adverse weather, for example storm.
In a design of a classical anchor, for example, Admiralty, there are following elements: longitudinal core (spindle) which is an anchor basis. In the top part of a spindle there is a bracket, intended for fastening of an anchor to an anchor chain, and also horns in the lower part which pass in paws with edges — socks. Horns not movably fasten to the anchor basis, and knot of fastening is called the trend. The lower side of a trend is called a heel. In some anchors for increase in coupling with soil there is a rod — the core focused across a spindle.
Main types of anchorsFurther we suggest to examine the most widespread types of anchor devices for today, and also briefly to describe their pluses, minuses and features.
Cons. Badly takes solid soil, can lie down sideways and creep. Has the small size of paws that negatively affects the holding force in comparison with more modern anchors.
Cons. Same, as at CQR
Cons. The majority of tests in which Bruce was involved, recorded rather small holding force.
Cons. At a swing of the vessel standing on this anchor there can be a situation, at which anchor can be pulled out from soil by the anchor end which got between paws. The long spindle complicates procedure of storages of Danforthon the boat.
Cons. Narrow paws badly keep in silt and sand. A long rod at an angle of 90 degrees in relation to paws creates inconveniences in work with it on the deck. Assembly and dismantling of this anchor is necessary.
Cons. The main advantages of this anchor can be attributed little weight, swivel legs and high holding power anchor for such class of devices. It is great for a short stay in the sea in favorable weather conditions.
Cons. Big dimensions at the expense of what it is inconvenient to store.
