About company

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 viewing in 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.
