Singapore sailors Loh Jia Yi and Jonathan Yeo were crowned world champions late Friday night in the boys' 420 class at the International Sailing Federation Youth Sailing World Championships in Tavira, Portugal.
The duo edged out 31 other teams from as many countries in the regatta to finish first, ahead of Malaysia's Mohammad Faizal Norizan and Ahmad Syukri Abdul Aziz, and Japan's Ibuki Koizumi and Kotaro Matsuo.
Said Jonathan, 18, shortly after the win: "I am the happiest person in the world right now. We had tears of joy and I am just speechless. I am just really grateful for everyone who has helped me and my partner."
Team-mate Ryan Lo also won a bronze in the boys' Laser Radial event, behind Spain's Joel Rodriguez Perez and Ireland's Seafra Guilfoyle in the 57-strong fleet.
The two medals make it the Republic's best finish at the Isaf Youth Worlds, Singapore the fifth-best performing nation at the regatta behind Spain, France, Israel and Italy.
Kimberly Lim and Savannah Siew missed out on a podium finish in the girls' 420 event, finishing fourth.
