Editing Anchor (section)

=== Scoop type anchors ===
Three time circumnavigator German Rolf Kaczirek invented the Bügel Anker in the 1980s. Kaczirek wanted an anchor that was self-righting without necessitating a ballasted tip. Instead, he added a roll bar and switched out the plough share for a flat blade design. As none of the innovations of this anchor were patented, copies of it abound.

Alain Poiraud of France introduced the scoop type anchor in 1996. Similar in design to the Bügel anchor, Poiraud's design features a concave fluke shaped like the blade of a shovel, with a shank attached parallel to the fluke, and the load applied toward the digging end. It is designed to dig into the bottom like a shovel, and dig deeper as more pressure is applied. The common challenge with all the scoop type anchors is that they set so well, they can be difficult to weigh.
* ''Bügelanker'', or ''Wasi'': This German-designed bow anchor has a sharp tip for penetrating weed, and features a roll-bar that allows the correct setting attitude to be achieved without the need for extra weight to be inserted into the tip.<ref>Ginsberg-Klemmt, Erika & Achim, and Poiraud, Alain (2007) ''The Complete Anchoring Handbook'', Ragged Mountain Press, {{ISBN|0-07-147508-7}}</ref>
[[File:Single-anchor1.png|thumb|Spade anchor]]
* ''Spade'': This is a French design that has proven successful since 1996. It features a demountable shank (hollow in some instances) and the choice of galvanized steel, stainless steel, or aluminum construction, which means a lighter and more easily stowable anchor.<ref>Poiraud, Alain (2003) ''Tout savoir sur le mouillage'', Loisirs Nautiques, {{ISBN|2-914423-46-2}}</ref> The geometry also makes this anchor self stowing on a single roller. The Spade anchor is the anchor of choice for Rubicon 3, one of Europe's largest adventure sailing companies<ref>{{Cite web |last=admin |date=2023-12-12 |title=How to Anchor a Boat |url=https://www.rubicon3adventure.com/articles/seamanship-sailing-skills/how-to-anchor-a-boat/ |access-date=2023-12-12 |website=Rubicon 3 Training & Adventure |language=en}}</ref>

* ''Rocna'': This New Zealand spade design, available in galvanised or stainless steel, has been produced since 2004. It has a roll-bar (similar to that of the Bügel), a large spade-like fluke area, and a sharp toe for penetrating weed and grass. The Rocna sets quickly and holds well.<ref>Lowe, Colin: "Gear Test: Rocna Anchor", Boating NZ, July 2006</ref>
[[File:Mantus.JPG|thumb|Mantus anchor]]
* ''Mantus'': This is claimed to be a fast setting anchor with high holding power. It is designed as an all round anchor capable of setting even in challenging bottoms such as hard sand/clay bottoms and grass. The shank is made out of a high tensile steel capable of withstanding high loads. It is similar in design to the Rocna but has a larger and wider roll-bar that reduces the risk of fouling and increases the angle of the fluke that results in improved penetration in some bottoms.<ref>{{cite web |url= https://www.practical-sailor.com/sails-rigging-deckgear/an-inquiry-into-anchor-angles |title=An Inquiry into Anchor Angles: Comparing fluke angle and setting ability |last= Nicholson |first= Darrell |date= 13 January 2017 |publisher= Practical Sailor }}</ref>
* ''Ultra'': This is an innovative spade design that dispenses with a roll-bar. Made primarily of stainless steel, its main arm is hollow, while the fluke tip has lead within it.<ref>{{Cite web|url=https://www.ultramarine-anchors.com/|title=Anchor|first=CloudSailor|last=s.r.o|website=Ultra Marine Anchors}}</ref> It is similar in appearance to the Spade anchor.

* ''Vulcan'': A recent sibling to the Rocna, this anchor performs similarly but does not have a roll-bar. Instead the Vulcan has patented design features such as the "V-bulb" and the "Roll Palm" that allow it to dig in deeply. The Vulcan was designed primarily for sailors who had difficulties accommodating the roll-bar Rocna on their bow.<ref>{{Cite web |url=http://rocna.cmpgroup.net/vulcan |title=Vulcan website |access-date=7 March 2019 |archive-url=https://web.archive.org/web/20190308080801/http://rocna.cmpgroup.net/vulcan |archive-date=8 March 2019 |url-status=dead }}</ref> Peter Smith (originator of the Rocna) designed it specifically for larger powerboats. Both Vulcans and Rocnas are available in galvanised steel, or in stainless steel. The Vulcan is similar in appearance to the Spade anchor.

* ''Knox Anchor'': This is produced in Scotland and was invented by Professor [[John Knox (chemist)|John Knox]]. It has a divided concave large area fluke arrangement and a shank in high tensile steel. A roll bar similar to the Rocna gives fast setting and a holding power of about 40 times anchor weight.<ref>{{Cite web|url=http://www.knoxanchors.com/performance-comparison2/|title=Performance Comparison|website=Knox Anchors|language=en-US|access-date=2017-07-10}}</ref>{{clarify|40 times weight on what bottom, with what scope. claim is meaningless without specifying the conditions of testing|date=August 2021}}
