The original SEC POOL anchors are (Super) High Holding Power anchors. This means that the POOL  anchor has proven to have at least two (four) times the holding power of a conventional anchor. Classification societies allow a weight reduction by 25-(50) % relative to the prescribed weight according to the tables of equipment. This has the following advantages:

  	Less weight to carry during the lifetime of the vessel.
  	More safety, as the remaining holding power still is at least 1.5 (2.0) times the holding power of a conventional anchor

Most original SEC POOL anchors are over-balanced, which means that the flukes will always stay vertical when the anchor is heaved. Advantages of a balanced anchor are:

  	It is possible to make use of a "narrow" anchor pocket, which hides the anchor completely and prevents it from becoming a wave breaker. SEC can assist in designing such a pocket for a POOL  anchor.
  	Damage to the vessel's hull caused by
sidewards pointing anchor flukes during heaving will be significantly reduced.
  	The anchor will always come homesmoothly without the fluke tips catching behind edges.

The advantages of welded plate-material anchors by comparison with casted anchors, are:

  	The anchor can easily be made out of other materials, such as a-magnetic or stainless steel.
  	It is easy to manufacture intermediate weights, since models can vary.
  	Small dimensional deviations from the standard, within tolerances given by the classification societies, are easy carried out (such as shortening the shank).
  	When, due to extreme circumstances, a POOL anchor is damaged, it is easily repaired by replacing the damaged parts.

The original SEC POOL anchors have big crownplates, which prevent the anchor from digging in too deep. This results in a relatively low breakout-force. It has the following advantages:

  	Quick and safe heaving.
  	Fewer losses due to stock anchors.
  	Less damage to the anchors.
