John W. Henry

John W. Henry, born 1949, made his money in trend-following futures: John W. Henry & Company, founded in 1981 and run out of Boca Raton, was among the largest managed-futures firms in the world before he returned outside capital and wound it down in 2012. He bought the Boston Red Sox in 2002 and broke the franchise's 86-year title drought two years later, added Liverpool FC in 2010, and holds both inside Fenway Sports Group alongside NESN, RFK Racing and a stake in the Pittsburgh Penguins. Net-worth estimates put him around $6B.

N627JW is a 2022 Gulfstream G500 (GVII-G500, S/N 72110, hex A8311B), registered to Algonquin Aviation LLC at 433 Plaza Real, Boca Raton. The registry names the company and no individual, so the tie to Henry is inference rather than record: Boca Raton is where John W. Henry & Company was always based, and the tail carries his initials. Planespotters files the airframe under Algonquin Aviation with no owner label attached. Treat the attribution accordingly — it is the same press-and-inference standard as most of this roster, not the registry-level confirmation that a named registrant would give.

His 66-metre yacht Elysian is tracked separately by our sister site, so the profile carries both hulls and airframe.

Boca Raton is the registered base and the likely winter anchor, with Boston the obvious counterweight in season and Liverpool the transatlantic leg. None of that is observed yet — this is a new entry with no tracked flights, so the map will populate from ADS-B rather than from expectation.
