our values as a small business

Our Commitment

Supporting Sustainable Tourism

Eternal Tides is driven by three pillars of sustainability, integrating them into all aspects of the business.



We are focused on becoming the leading ecotourism operator on O’ahu and beyond. We are strongly committed to educating our guests on marine and terrestrial wildlife conservation, ocean environment preservation, and sustainable natural resources.


The environment is intrinsically linked to our health and well-being. Water is life, and we strongly believe everyone has a part to play in conservation and can be ocean stewards for themselves, their families, and their communities.


Communicating Scientific Research

Eternal Tides was founded by scientists and avid environmentalists whose goal is to engage everyone who sails with ongoing scientific research. Most traditional Western scientific findings are only disseminated among academic circles, which circumvents those that are actually affected in local communities. There are limited programs where tourists can participate in ongoing scientific research. We hope to provide opportunities for education, clear science communication, and participation of non-scientists in ongoing research and ecosystem support.

Join us aboard the Blue Planet for an engaging and educational experience! Dive into hands-on water quality monitoring as we embark on a mission to contribute to a seasonal time series tracking the water quality off the coast of Waikiki. Our guests will actively participate in data collection at three key sites: Kewalo Channel, Ala Wai Channel, and the deep ocean off Waikiki. Witness the impact of your efforts unfold through online visualizations showcasing the evolving water quality over time. Come aboard, be part of the research, and let’s explore the oceans together!

Discover the wonders of marine life aboard the Blue Planet through our engaging research initiative! Guests have the unique opportunity to participate in Plankton Tows, a powerful oceanographic tool used to sample microscopic life in the ocean.

During this activity, a jar is attached to the end of the net, trailing behind the boat or dingy. As the net is pulled through the water, excess water exits through the mesh netting, while plankton is expertly trapped into the jar at the end.

The mesh netting’s size determines the types of plankton you’ll collect. Large mesh netting exclusively captures large zooplankton (animal plankton), while smaller netting allows for the collection of both large zooplankton and phytoplankton (plant-like plankton). At Blue Planet, we use the smallest mesh netting possible to provide a comprehensive view of both zoo and phytoplankton.

Following your plankton tow, explore the intriguing world of these microscopic organisms. Not only will you gain insights into ocean organism reproduction, but you might also uncover valuable information about ocean temperature and currents. Join us for an educational and immersive journey into the heart of marine research!

Embarking on our sailing tours involves more than just breathtaking moments out on the water. If we’re lucky, we’ll see whales (whale season is December – March) and have a moment with these majestic creatures. We actively contribute to conservation efforts through respectful engagement and photography.

Capturing images of humpback whale flukes is a significant part of our mission. We share these photos with HappyWhale, where photography contributes to scientific research and conservation. By identifying individual whales through their unique markings, we play a vital role in engaging citizen scientists worldwide. Together, we contribute to a global initiative that tracks and safeguards these incredible beings across the oceans. Join us on a journey where your passion for whale watching becomes a meaningful act of conservation through the lens of respect and responsibility.

Respecting Hawai’i

The consumptive model of tourism in Hawai’i is harmful to the land, and the Native Hawaiian community, and a diverse local economy not dependent on tourism is needed to reduce this harmful reliance. Although Eternal Tides operates in tourism, we hope to contribute to a new model of business not based on rapid consumption and exploitation of land and resources. Instead, we hope to support existing initiatives spearheaded by the Native Hawaiian Community. There are a few ways we try to give back and hold ourselves accountable

As a company, we are committed to making a positive impact on the world. That’s why we are proud to announce that we will be donating 1% of our gross profits to various charitable organizations that work towards making the world a better place. We’re a member of 1% For the Planet and hope to expand well beyond just a

Hawai’i Marine Animal Response (HMAR) stands as the largest nonprofit marine conservation and response organization in Hawai’i, fueled by dedicated volunteers, interns, and staff. Operating on O’ahu and Molokaʻi, HMAR thrives on a blend of private donations, corporate funding, and government grants. With a mission encompassing education, threat mitigation, and essential assistance to distressed animals, HMAR’s six distinctive programs weave together seamlessly. From outreach and education to field support, interventions, rescues, and stranding response, our initiatives aim for a harmonious coexistence between humans and marine protected animals, including Hawaiian monk seals, sea turtles, and seabirds. Join us on this journey toward a thriving ocean ecosystem.

The Eternal Tides crew is proud to be Hawai’i Marine Stewards, having completed HMAR’s specialized training focusing on the protection and preservation of Hawai’i’s marine wildlife, led by scientists and wildlife guides within our crew.
