Whale watching tour guides for the Atlantis Navatek say they had the most successful tour this season.
Spectators boarded the boat at the Aloha Tower piers for a two-hour tour and say they got more than they bargained for.
"It was wonderful. I mean, it was like they were showing off just for us. When they got so close you realize just how enormous these animals really are,” said Whale Spectator Rebecca Maguire.
The spectator group saw about seven humpback whales in a very competitive pod with chin slapping, breeching, tail slapping and spy hopping – all activities whale naturalists record during each sighting.
"We take pictures of their flukes. That way we can take track of the whales we are seeing from day to day in the season,” said Whale naturalist Kristi Layman.
Scientists say there are around 20,000 whales in the ocean and around 10 to 12,000 migrate down to Hawaii's warm waters to breed.
Whale season started back in November and will end in May.
