SemiSub is one of the world’s most luxurious high-tech watercraft. After a warm Hawaiian greeting at the world famous Aloha Tower piers, guests enjoy a short sail to a special reef location specifically selected for its underwater beauty.

Once positioned, the vessel partially submerges and guests are escorted into one-of-a-kind underwater pods for approximately 20 minutes of viewing time on comfortable seats.

Guests are encouraged to take photos and videos of the beautiful reefs and marine life, and often Hawaiian sea turtles and even reef sharks are seen.

When not in one of the special viewing pods, guests relax on deck in comfortable captain-style chairs and enjoy a delicious continental style meal prepared by world-renowned Chef Chai.

A special video showcases the beautiful underwater world and the key role played by our precious reefs.

Of course, the view of one of our planet’s most beautiful coasts provides marvelous photo opportunities and memories for a lifetime.
