About us

Now you have a choice as to how you interact with whales, dolphins, sea turtles, and coral reefs up-close and personal. You can join them in the water or watch them through our amazing magnified boat’s glass bottom. A coral reef in 20 feet of water looks close enough to touch!

The Boat

Our unique vessel is one of only two in the United States, and of a handful in the world.  It’s spaceship-like aerodynamic shape  allows us to travel quickly and smoothly through the water AND conserve fuel.

The Ride

The Ride

Our boat doesn’t go through the water but above it. The hydrofoil design eliminates the pounding you experience on regular boats. This boat is amazingly comfortable in all kinds of seas.

Underwater

Most people miss 80% of what is in the water when they snorkel – because they don’t know what to look for and haven’t developed an eye for spotting creatures.  Our guides will not only make sure you see animals but will also explain what those animals are actually doing.

The Culture

Our goal is to show you how Nature and Culture are intricately intertwined. Hawaiian culture has a deep respect for the ‘aina, the Earth, and for the wisdom and knowledge of their ancestors.

The view from the boat.

The View

Our boat boasts the largest glass bottom in the world and because it is curved, what you see is magnified. It is is made of modified acrylic 15 mm thick.  It is more solid than a fiberglass boat hull.
