Japan back on track with Tokyo 2020 Olympics preparations
This led IOC coordination commission chairman John Coates to warn 2020 organizers they had to be "prepared to answer these questions when they are raised", or confidence could waver.
"We had some concerns at the beginning of the year but we have seen a huge amount of activities over the last few months leading up to this first test event and World Cup," Alastair Fox, director of events for World Sailing, told reporters.
The sailing federation will gather feedback from the sailors and race officials, said Fox, adding: "We'll sit down with our Tokyo friends and we'll plan ahead for 2019 test events and for the Olympic Games."
But he claimed organizers had made "big progress" since then, talking to the coastguard about safety and to fishermen about organizing the field of play.
"We don't think our preparations are largely behind schedule," said Naito.
