Pen Duick (Breton for coal tit; literally pen = head; du = black; ick = diminutive, small)
Tabarly's first major success was winning the Pen Duick II in the Observer Singlehanded Transatlantic Race (OSTAR) from Plymouth to Newport (Rhode Island) in the USA.
For the regattas, he develops various yachts, some of which have very innovative designs.
In addition to regatta trips, Tabarly's passion was the classic yacht Pen Duick, built in 1898 to a design by William Fife III, which he had taken over and restored from his father.
