bowsprit
The bowsprit of a sailing vessel is a spar extending forward from the vessel's prow. It provides an anchor point for the forestay(s), allowing the fore-mast to be stepped farther forward on the hull.〔(【引用サイトリンク】url=http://www.classicmarine.co.uk/articles/Bowsprit%20Article.htm )〕
==Origin==
The word ''bowsprit'' is thought to originate from the Middle Low German word ''bōchsprēt'' - ''bōch'' meaning ''bow'' and ''sprēt'' meaning ''pole''.〔(【引用サイトリンク】url=http://www.thefreedictionary.com/bowsprit )〕 Early ocean-going vessels tended to tilt the bowsprit, also known in centuries past as a ''boltsprit'', at a high angle, and hung one or two square spritsails from yards. In the 17th century and early 18th century a vertical sprit topmast was added near the end of the bowsprit and another square sail added to it; this was not a particularly successful design however, the mast tending to carry away in heavy weather. Fore-and-aft sails known as jibs hung from the stays proved more useful for speed and manoeuvring, and the basic bowsprit was lengthened with a jibboom and then even further with a flying jibboom, resulting in bowsprits of tremendous length, up to 30 metres total.
