Byer's plan, the flukes and crown consist of a steel-casting secured to a forged shank by a through bolt of mild steel, the axis of which is parallel to the points of the flukes; one end of the bolt has a head, but the other is screwed and fitted with a phosphor bronze nut to allow the bolt to be withdrawn for examination.

A palm is cast on each side of the crown to trip the flukes when the anchor is on the ground, and for bringing them snug against the ship's side when weighing. Wasteneys Smith's anchor is composed of three main parts, the shank and crown which form one forging, and the two flukes or arms which are separate castings.

A bolt passes through the crown of the anchor, connecting the flukes to it; to prevent the flukes working off the connecting through bolt, two smaller bolts pass through the flukes at right angles to the through bolt and are recessed half their diameter into it. Small boat anchors have developed a bit separately from the first half of the 20th century, with the advent of the "CQR"developed by Geoffrey Ingram Taylor of Scotland in the early s.

This design was not symmetrical, and required the use of a bow-roller design to effectively stow it.

This is practical for small boats and yachts, but does not scale in a practical manner for large shipping. The CQR is now manufactured by Lewmar.

American Richard Danforth invented and developed the "Danforth" pattern in the s, a return to the symmetrical concept but with very large flat plate flukes. This anchor offers very good holding power for its weight high efficiency but does not perform well in other respects, meaning that it is not a good general purpose anchor.

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. New generation anchors have come into force since the latter part of the 20th century.

The German "Buegelanker" features a simple single flat triangular fluke, with a roll-bar to ensure correct setting. A surprisingly simple design, this has proven more effective than its ancestors.

Frenchman Alain Poiraud developed the "Spade" anchor in the s, a huge leap in performance over any types which proceeded it.

theme, will take

The Spade was the first anchor to successfully make use of a concave fluke, which provides the greatest efficiency as opposed to the convex "plow" type of the CQR, or the flat "plate" type of the Danforth.

The "Bulwagga" is essentially a modified fluke style anchor which made itself known at the very beginning of the s. Rather than two flukes in a symmetrical configuration, it adds a third for an equilateral triangular arrangement.

sorry, that has

This concept is an improvement over the Danforth in terms of general purpose usage, but is slightly comparatively inefficient on account of the fact that one fluke is always unuse and is difficult to stow.

New Zealander Peter Smith in the early s took elements of the Spade and other types, and developed unique solutions of his own, in order to design the "Rocna" anchor, a general purpose type which uses a concave fluke, a self-righting roll-bar, and setting skids.
