Hydroptère is a French experimental sailing hydrofoil trimaran imagined by the yachtman Éric Tabarly.

The design is based on experience from a range of hydrofoil sailcraft that Thébault built in cooperation with Éric Tabarly since the 1980s.

[7] During July 2015, the Hydroptère sailed 2215 nautical miles from Los Angeles to Honolulu and docked in Kewalo Harbor.

[8] On 15 March 2016 the Harbor Master posted an "Abandoned Vessel" notice on the Hydroptère[9] which was subsequently sold at auction.

[12][13] In November 2019, l'Hydroptère was sailed from Honolulu, Hawaii to San Francisco, California by professional sailor Mike Price and a delivery crew so that she could undergo an extensive re-fit.
