It was a day of frustration at the ISAF Sailing World Championships as inadequate winds severely affected racing on Monday.
A total of eight classes were scheduled to compete in the Spanish port of Santander on the fourth day of qualification races.
However, of the 35 races supposed to be taking place only two were able to be held due to a combination of wind shifts and a strong current.
The two races that did commence came in the yellow fleet of the 49er class, where the Austrian pairing of Nico Delle Karth and Nikolaus Resch claimed the overnight lead with a strong showing.
Two fifth-place finishes saw the duo move to the head of the leaderboard in difficult conditions as the majority of their competitors struggled to produce their best.
Russia's Artem Basalkin and Nikolay Chernikov sit second following finishes of third and eighth, while Pavle Kostov and Petar Cupac of Croatia occupy third as they won their second race after coming 11th in the first.
But European silver medalists Dylan Fletcher-Scott and Alain Sign's hopes of qualifying for the 25-boat gold fleet and keeping their medal prospects alive are in serious doubt.
Brits Fletcher-Scott and Sign are 35th in the overall standings courtesy of a disqualification in the first race and 21st-place finish in the second.
