An anchor frequently appears on the flags and coats of arms of institutions involved with the sea, as well as of port cities and seacoast regions and provinces in various countries. There also exists in heraldry the "Anchored Cross", or Mariner's Cross, a stylized cross in the shape of an anchor. The symbol can be used to signify 'fresh start ...
A deep-penetrating anchor (DPA) is conceptually similar to a torpedo anchor: it features a dart-shaped, thick-walled, steel cylinder with flukes attached to the upper section of the anchor. A full-scale DPA is approximately 15 metres (49 ft) in length, 1.2 metres (4 ft) in diameter, and weighs on the order of 50–100 tonnes (49–98 long tons ...
A fender system consists of the fender (boating) itself, the panel, and the various hardware required to anchor and stabilize the unit. Fenders are made of a grade of rubber chosen for their flexibility. The more compressible, the more energy the fender can resist. They come in multiple sizes and shapes, aimed at handling different situations.
Multiple anchor mooring systems use two or more (often three) light weight temporary-style anchors set in an equilateral arrangement and all chained to a common center from which a conventional rode extends to a mooring buoy. The advantages are minimized mass, ease of deployment, high holding-power-to-weight ratio, and availability of temporary ...
Bruce Anchor Co has its primary role in the very large anchor business, producing mooring anchors and permanent installation types for heavy industry, such as oilrigs. On the back of this reputation, the Bruce small boat anchor type was initially very successful, and represented some significant improvements over the CQR. It is no longer produced.

The tensioned portion of the rope would fasten the ship to the quay, hoist a foresail, lift a spar into position on the mast or be used to transfer cargo to or from a dock or lighter. A capstan is a vertical- axled rotating machine developed for use on sailing ships to multiply the pulling force of sailors when hauling ropes, cables , and hawsers .
The stockless anchor is an improved version of the Admiralty anchor it is derived from. It has two flukes that pivot on the same plane perpendicular to the shank. [2] The weight of the shank and accompanying chain, or the shank angled under tension, keep the anchor laying flat on the sea floor.
