==Hand bailers== A hand bailer is a device used for manually removing water which has entered a vessel. In the simplest case, it is merely a smaller container which can be filled and then emptied. This kind of device has been in use since early times. It is still in use on small boats and rafts, though some are ''self-bailing''. Some regulations require either or both forms of bailing.<ref>ISO 9650 Small craft, inflatable liferafts [http://www.4ocean.si/novice/Rules/ISO_9650-1_2005_PDF_version_(en).pdf 2005(E) (pdf-file 244 KB)] {{Webarchive|url=https://web.archive.org/web/20120915230030/http://www.4ocean.si/novice/Rules/ISO_9650-1_2005_PDF_version_(en).pdf |date=15 September 2012 }}</ref><ref>ISAF (International Sailing Federation), liferafts</ref>

==Self bailers== For some modern types of dinghies in sailing sports hand bailers can be obsolete when they are equipped with self bailers, sometimes also called automatic bailers. Self-bailing boats are shaped so that they will drain completely if filled with water; powered by the venturi effect and the motion of the boat, they are distinct from the powered bilge pumps used on non-self-bailing boats.
