Several editions of the [[America's Cup]] have been raced with foiling yachts. The 2013 and 2017 editions used the [[AC72]] and [[AC50]] classes of [[catamaran]] respectively, and the 2021 edition used the [[AC75|AC75 class]] of foiling monohulls with canting arms.

The French experimental sail-powered hydrofoil ''[[Hydroptère]]'' is the result of a research project that involves advanced engineering skills and technologies. In September 2009, the ''Hydroptère'' set new sailcraft world speed records in the 500&nbsp;m category, with a speed of {{convert|51.36|knot|km/h}} and in the {{convert|1|nmi|m|round=0.5|comma=5}} category with a speed of {{convert|50.17|knot|km/h}}.<ref>{{Cite web|url=http://www.sailspeedrecords.com/index.php?option=com_content&view=article&id=104:wssr-newsletter-no-177-hydroptere-world-records-230909&catid=2:news&Itemid=5|title=World Sailing Speed Record Council|website=sailspeedrecords.com}}</ref><ref>{{Cite web|url=http://www.sailspeedrecords.com/index.php?option=com_content&view=article&id=105:wssr-newsletter-no-178-hydroptere-nautical-mile-201109&catid=2:news&Itemid=5|title=World Sailing Speed Record Council|website=sailspeedrecords.com}}</ref>

The 500&nbsp;m speed record for sailboats is currently held by the ''[[Vestas Sailrocket]]'', an exotic design which operates in effect as a hydrofoil.<ref>{{cite magazine |last1=Fisher |first1=Adam |title=How a Boat-Plane Hybrid Shattered the Sound Barrier of Sailing |url=https://www.wired.com/2013/01/ff-paul-larsen-sailrocket/ |magazine=Wired |access-date=10 May 2021}}</ref>

Another trimaran sailboat is the Windrider Rave.<ref>{{cite web | title=Windrider Wave | author=Windrider | url=http://www.windrider.com/rave.shtml | access-date=7 September 2009 | archive-date=9 May 2007 | archive-url=https://web.archive.org/web/20070509083641/http://windrider.com/rave.shtml | url-status=dead }}</ref> The Rave is a commercially available {{convert|17|ft|m|adj=on}}, two person, hydrofoil trimaran, capable of reaching speeds of {{convert|40|kn|km/h|abbr=on}}.  The boat was designed by Jim Brown.

The [[Moth (dinghy)|Moth dinghy]] has evolved into some radical foil configurations.<ref>{{cite news|url=https://www.irishtimes.com/sport/other-sports/gliding-on-top-of-the-water-is-still-sailing-but-not-as-we-know-it-1.1533581|newspaper=The Irish Times|date=September 20, 2013|first=David|last=Branigan|title=Gliding on top of the water is still sailing but not as we know it}}</ref>

[[Hobie Cat|Hobie Sailboats]] produced a production foiling [[trimaran]], the Hobie Trifoiler, the fastest production sailboat. Trifoilers have clocked speeds upward of thirty knots.

A new kayak design, called [[Flyak]], has hydrofoils that lift the kayak enough to significantly reduce drag, allowing speeds of up to {{convert|27|km/h|0|abbr=on}}. Some [[Surfing|surfers]] have developed surfboards with hydrofoils called [[foilboard]]s, specifically aimed at surfing big waves further out to sea.<ref>{{cite web  |title= Laird Hamilton: A Surfermag.com exclusive interview |author= Scott Bass |work= [[Surfer (magazine)|Surfer Magazine]] |year= 2009 |url= http://www.surfermag.com/features/onlineexclusives/lairdintrvu/ |access-date=2 December 2010}}
