There were just three boats, but over 30 races on Saturday.
Crews rotated in and out of the boats
It was a short course on the flat protected Wailoa River. The boat circled and crossed the finish line at the green flag.
In the bow of the boat, someone bangs a gong to set the rhythm.
The history of how the boats came to Hawaii from Okinawa was interesting to me and can be found at http://www.haariboatfestival.com/history.html
