Sunset over Oʻahu’s South Shore

Welcome Aboard Ocean Therapy Charters

Experience Waikīkī from the water with Ocean Therapy Charters, a boutique small-group charter company specializing in scuba diving, snorkeling, sunset cruises, whale watching and private boat experiences along Oʻahu’s South Shore.

​

Our trips are limited to a maximum of six guests, giving you a more personal, comfortable and unrushed experience on the water. Whether you are joining us for a certified scuba dive, learning to dive through PADI or SSI, snorkeling at Turtle Canyon, watching the sunset, enjoying Friday night fireworks or booking the boat privately for your group, our goal is to make every trip feel personal from start to finish.

​

Scuba divers can explore some of Oʻahu’s most popular wrecks and reefs, including sites such as the Sea Tiger, YO-257, San Pedro and South Shore reef systems. We also offer scuba certification and continuing-education courses for new and experienced divers, with small class sizes and personalized instruction.

​

Snorkeling guests can explore Turtle Canyon and other South Shore reefs while looking for Hawaiian green sea turtles, tropical reef fish and other marine life. Snorkel gear and flotation equipment are available, and our small-group format makes it easier to enjoy the experience without the crowds found on larger tour boats.

​

For guests who prefer to stay above the surface, we offer Waikīkī sunset cruises, Friday night fireworks cruises, seasonal whale watching and private charters for couples, families and small groups. Private charters can be customized around snorkeling, scuba diving, sunset cruising and other ocean activities.

​

Ocean Therapy Charters departs from Ala Wai Small Boat Harbor, Slip 65, conveniently located near Waikīkī. Our licensed captains, professional dive staff and experienced crew focus on safety, personal service and creating a relaxed day on the ocean.

​

Whether you are visiting Oʻahu for the first time or returning for another adventure, we would love to welcome you aboard.

​

Today is a great day for an adventure.
