Captains Courageous! :)
Dolphin Discoveries
is the result of Captains Kevin & Claudia Merrill's love of the ocean and the wonderful animals that live within.

The Merrill's have lived in Kona since the 1980's and for years have been studying and photographing the marine mammals in Kona as well as the Pacific Northwest, Alaska, Tonga, the Cook Islands and New Zealand. Their special interest is with the Spinner Dolphins, Pilot Whales, Bottlenose and Spotted dolphins, Green Sea turtles as well as seasonal Humpback Whales. They offer a unique learning adventure to observe and learn about dolphins, whales and other marine life that goes far beyond the ordinary tourist boat.


It is our hope, that the more people learn about the dolphins and whales, the more they will love them, and do what they can to protect them

See Nature as it was meant to be...
Wild & Free
