Jonathan Tyrrell, often known as Jon Tyrrell, is a British sailor described by the press as a regular of Royal Ocean Racing Club (RORC) races and an instructor. He has a long-standing partnership with Daniel Jones: the pair raced double-handed on the Sun Fast 3300 Wild Pilgrim, finishing third in IRC Two and first Sun Fast 3300 in the 2022 Sevenstar Round Britain & Ireland Race.
From 2024 Tyrrell skippered Gambit, a Guillaume Verdier-designed Pogo S4 launched in 2022 and owned by Daniel Jones. His first Class40 race was the 2024 CIC Normandy Channel Race, sailed double-handed with Ruaridh Wright, which ended in retirement. In 2025 he finished 17th in the Rolex Fastnet Race with Daniel Jones and Calanach Finlayson.
The 2026 season was his best so far: after seventh place in the Round Ireland Yacht Race, Gambit took second in the Class40 division of the RORC Round Britain and Ireland Race with an all-British crew (Daniel Jones, Calanach Finlayson, Ruaridh Wright). Third across the line, the boat moved up to second after the jury ruled that Penfret had not sailed the course.
