Editing Daggerboard (section)

===History===
In 2008, a {{convert|55|ft|m|adj=mid|-long}} daggerboard ship was found using deep scan sonar equipment off the southern shore of [[Lake Ontario]], the only such vessel known to have been found in the [[Great Lakes]]. Vessels of this type were used for a short time in the early 19th century.<ref name="AP2008">{{cite news|title=Upstate NY explorers ID rare boat in Lake Ontario |date=December 13, 2008 |agency=Associated Press |url=http://www.gmanetwork.com/news/story/139261/news/world/upstate-ny-explorers-id-rare-boat-in-lake-ontario/ |archive-url=https://archive.today/20130124100410/http://www.gmanetwork.com/news/story/139261/news/world/upstate-ny-explorers-id-rare-boat-in-lake-ontario/ |url-status=dead |archive-date=January 24, 2013 }}</ref>

In the early 19th century daggerboards were infrequently being used on American [[schooner]]s. These schooners were used for nearby coastal trade of cotton, wheat, and apples. A sunken 1833 daggerboard schooner was found in the great lakes with the help of sonar equipment.<ref>The Blade.

Daggerboards can be found on [[monohulls]] which is the classic sailboat and [[multihulls]] called catamarans. 

Daggerboards come in all different shapes and sizes, some curved or s-shaped. Curved daggerboards started to appear thirty to forty years ago. The first prototype was made in 1985 by Ian Farrier. The benefits of vertical lift generated by curved daggerboards are nominal. When actually sailing, curved daggerboards - not to be confused with hydrofoils - do not make a drastic change.<ref>(Boat Builder)</ref>
