Our Values – Our Culture

Nautilus boats are built for Safety
Built for Safety

Most divers would be shocked if they knew what was going on in the engine room and below decks of many liveaboard diving ships. Safety is not something to ever take lightly. We live and breathe safety with obsessive compliance to our Safety Management System under the watchful eyes of our external auditors. See our passenger and safety certificates here.

Our commitment to safety >

Luxurious Liveaboard Diving
Excellence in Guest Experience

Captain Mike has led the way for the last twenty-seven years in consistent and relentless obsessive attention to detail, and making every trip as excellent as possible. That attention to detail shows up everywhere, from each dive briefing, to the choice of dive sites, to dinner service, to the quality and thread count of our Egyptian cotton bed sheets. We never stop stressing over the details. We never stop trying to do even better.
