Hokule'a and Hikianalia are nearly two-thirds of the way to their first destination: the Tuamoto Atolls, north of Tahiti.
KITV spoke to master navigator Nainoa Thompson by satellite phone early Monday. He said judging by where they think they are, it's their fastest trip to Tahiti.
"We're doing good. Koku's in top shape, sailing better than ever. The weather's been awesome and the crew is getting stronger every day.
After a bad bout of sea sickness for many of the newer crew members, Thompson said everyone is healthy and working together to get to their destination.
"We had really good weather. We never had 10 percent cloudy evenings. This one has been really easy," he said. "I think we're at least five or six days ahead of schedule."
The apprentice navigators haven't hit any tough wayfaring issues, Thompson said. But that all depends on the weather.
On Monday, Thompson said they got out of the intertropical convergence zone two nights ago and were in the South Pacific where weather is noticeably different from the north Pacific and Hawaii.
"Its typically lighter winds than Hawaii and it's not as strong or rough as Hawaii," he said. "It's more .... gentle. At least in the tropics, it's warmer. Winds are more easterly. Basically like Hawaii weather on a mild day."
