Hong Kong skiff sailors found themselves in second to last place after completing the first day of their Paris Olympics races on Sunday.

The SAR's Akira Sakai and Russell Aylsworth ranked 19th out of 20 teams in the event after three races in Marseille.

They started off with 17 points in the first race, and improved to 12 points in the second. The final event of the day didn't turn out as well, as the pair finished with 19 points.

Sailors with the fewest points win.

Team China's pair of Wen Zaiding and Liu Tian are tenth after race day one, while New Zealanders Isaac McHardie and William McKenzie have taken the top spot so far.

The medal rounds are due to take place on Thursday.

Meanwhile, the windsurfing competitions were postponed for the day due to a lack of wind. Hong Kong's Alex Cheng and Mui Ma are in the men's and women's events, respectively.
