Light winds played havoc with the sailors at the Rio test event today.
Only two classes featuring New Zealanders were raced but both had delays.
The women's 49erFX finally began about 2.30pm local time but New Zealand's Alex Maloney and Molly Meech had a tough day, but still sit fifth overall. They were 12th in their first race and eighth in the second, which was a good comeback from a rough start.
"It was a tough day on the race course, pretty light, shifty and a bit of current effect as well - so a little bit of everything out there today," 49erFX coach Jim Maloney said.
Brazil's Martine Soffiatti Grael and Kahena Kunze have used hometown advantage impressively and lead the fleet with 11 points, while New Zealand have 29.
