Boonchu grew up playing golf at the Royal Army Course and has helped young golfers, including Thaworn Wiratchant, along the way. Initially started his sporting career in kick-boxing but was knocked out cold in his third bout and quit the game. Possesses a classic golf swing. When he retires, he says he will devote time developing junior golf and possibly play on the US Champions Tour. He opened up a restaurant in Bangkok in 2003.
Widely respected by his fellow professionals, Thailand’s Boonchu Ruangkit is one of Asia’s greatest ever players and golfing ambassadors. Proved that old is gold when he won the Thailand Open in 2004 en route to a glorious season where he posted six top-10s, including two runner-up finishes. In 2006, Boonchu managed a tied 21st place finish at the Brunei Open. Boonchu then broke the deadlock in his third attempt at the Champions Tour when he finished on top at the Champions Tour Qualifying School. Posted back-to-back sixth place finish in the Philippine Open and Maekung Open in 2005. Made a winning debut at the Visa Dynasty Cup in China in 2005. Attempted to qualify for the US Champions (Seniors) Tour as well but missed out on the first stage. Hit the opening drive on the former Asian PGA circuit in 1995 and again on the newly-formed Asian Tour in 2004 at the Thailand Open. Winning his second Thailand Open title, the first was in 1992, made him the oldest winner in Asia at the age of 47 then. Produced three top-10s in 2003, including a tied fourth finish at the Volvo Masters of Asia. Won the Singha Classic, a Thai Tour event in 2003. Enjoyed an impressive amateur career. Won the 1985 Australian Amateur Championship and Putra Cup (team and individual) that same year.
He almost made history on his native continent in 2009 by becoming the oldest winner in the history of the Asian Tour but was preceded to the Brunei Open title by Australian Darren Beck. However his entry into the history books was only delayed until the beginning of the 2010 season when he began competing on the European Senior Tour. There, with victories in Brunei, Thailand and South Africa, he became the first player since Tommy Horton in 1997 to win three consecutive tournaments on the Senior circuit and also became the quickest player to achieve three victories, doing so in seven tournament appearances which was one fewer than the previous record holder, Brian Huggett. Furthermore, during his victory in the Chang Thailand Senior Masters, his 21 under par total of 195 was not only the lowest 54 hole score to par in the history of the European Senior Tour, his 11 stroke victory over his nearest challenger was also the greatest recorded for a 54 hole event since the Senior Tour began in 1992.
Was the medalist at the 2006 Champions Tour National Qualifying tournament.
