John Sebastian Östling (born 2 June 1984 in Onsala, Kungsbacka) is a Swedish sailor, who specializes in the 470 class, a two-person dinghy.[1][2] He represented Sweden, along with his partner Anton Dahlberg, in two editions of the Olympic Games (2008 and 2012), and has also been training representing Royal Swedish Yacht Club throughout most of his sporting career under his personal coach and mentor Per Frykholm.[1]
Östling made his Olympic debut at the 2008 Summer Olympics in Beijing, where he paired up with skipper Dahlberg in the men's 470 class. The Swedish duo finished 15th in a ten-round opening series with a net score of 111, trailing Israelis Gideon Kliger and Udi Gal by a narrow, three-point gap from the final standings.[5]
At the 2012 Summer Olympics in London, Östling competed for the second time as a crew member in the men's 470 class by finishing eleventh and receiving a berth from the ISAF World Championships in Perth, Western Australia.[6][7] Teaming again with Dahlberg in the opening series, the Swedish duo mounted four top 10 finishes to guarantee a spot in the final race, but fell short for the podium with an accumulated net score of 123 points and a tenth-place finish in a fleet of twenty-seven boats.[8][9]
