Water sports competitions, including swimming, diving, and beach volleyball, will be held during the festival.
"Traditional culinary delicacies and arts of Natuna will be promoted at the festival," Buralimar, head of the Riau Island Tourism Office, remarked here on Wednesday.
Foreign yachts are expected to participate in the festival, akin to the earlier years.

In addition to the Senua Isle Festival, Natuna will organize the Padang Melang Festival in Anambar in July 2019, Tour de Kepri in October 2019, and Bahari (Maritime) Festival in November this year.
