B.O.S.S. is an acronym for Breathing Observation Submersible Scooter.


BOSS is a unique and very exciting underwater motor scooter which works with the bell theory. Remember in school when you would turn a glass upside down in a sink of water and no water would enter the glass? It's the same concept with the BOSS unit. As we descend you, a seal is formed and you are dry inside the bubble!

Aqua Adventures LLC originated the underwater motor scooter tour in St Thomas in 2002. Originally known as the BOB Underwater Adventure, we've changed our name to differentiate ourselves from other tour operators who have tried to compete with us, but just don't meet the standard of excellence we demand.


Royal Caribbean, Celebrity, Carnival, Princess Cruise Lines and Norwegian Cruise Lines are proud to offer the BOSS Tour! You can book your excursion directly with them when you are onboard, or you can book through their respective websites. Make sure you book early, because BOSS sells out! There is nothing quite like this tour, and we want you to join us!
