Joseph Koh Seng Leong (born 19 September 1983) is a Singaporean former sailor, who specialized in the Laser and 470 classes.[1] He represented Singapore across two editions of the Summer Olympic Games (2000 and 2008), finishing outside the top twenty-five each in two separate boats, respectively. Outside Olympic career, Koh collected a total of two medals in a continental regatta, spanning the 2006 Asian Games in Doha and the 2007 Southeast Asian Games in Nakhon Ratchasima.[2][3] Koh trained throughout his sporting career at SAF Yachting Club in Changi, under the tutelage of his personal coach Brett Beyer, a six-time Laser Apprentice Master world champion from Australia.[4]
At the age of 16, Koh became the youngest sailor to compete in Sydney 2000. There, he and his partner Tan Wearn Haw finished twenty-eighth in the men's 470 class with a net grade of 192, sparing them from the back of the fleet by a twelve-point edge over the Hungarian duo of Marcell Goszleth and Ádám Szőrényi.[5] Switching to a single-handed dinghy, Koh sought to bid in the open Laser for Athens 2004, but he lost the selection to two-time Olympian Stanley Tan. In 2005, Koh had his left hand fractured in a freak motorbike accident, impelling him to sail a boat in the forthcoming regattas with a modified technique.[6]
Eight years after competing in his maiden Games, Koh qualified for his second Singaporean team, as a 24-year-old, in the Laser class at the 2008 Summer Olympics in Beijing. He finished twenty-third out of 52 sailors in the silver fleet to lock one of the ten quota places available at the Worlds six months earlier in Terrigal, New South Wales.[6][7] Koh stayed in the middle of the fleet throughout the series, until he chased harder to finish third on the penultimate leg by a few marks ahead of Poland's Maciej Grabowski. Koh's best result, however, was not enough to reach the top of the overall scoreboard, sitting him in thirty-sixth with 239 net points.[8]
