On one of Oahu's newest and largest sailing catamarans—a 65-foot (19.8-m) custom-built yacht—cruise along the beautiful leeward coast to see dolphins and turtles with breakfast and lunch onboard. Dolphin sightings are guaranteed or you sail again free and during humpback whale season in December to March either whales or dolphins are guaranteed

After boarding the catamaran, set off to snorkel at a calm spot to see vibrant fish, coral, dolphins, and other marine sights just beneath the surface. In-water help is provided by the lifeguard-certified crew and after snorkeling, nibble on a sandwich lunch. Unlimited nonalcoholic beverages and 2 alcoholic drinks are included.

Ample shade, indoor and outdoor seating, restrooms, a sound system, a freshwater rinse shower, and a full-service bar are on the comfortable catamaran, one of the biggest of its kind on the island. Enjoy the service and knowledge of Hawaii's first activity provider certified Dolphin SMART—a NOAA (National Oceanic and Atmospheric Administration) recognition of eco-friendly practices.

A portion of all proceeds helps fund the Hawaii Nautical Marine Life Foundation—which supports charitable efforts in the environmental and educational sectors—meaning going on this trip helps give back to the community and the environment. With door-to-pier transportation from your crew, the repeat winner of TripAdvisor's annual Certificate of Excellence provides exceptional value.
