Your Home at sea

Our liveaboard diving ships were constructed with careful consideration. Relentless and obsessive attention to safety has been a cornerstone of our business from our very early days in the 1980’s.

We launched the Belle Amie in 2015 and she is a beauty. Modern. Super spacious. Designed specifically for Socorro. Featuring suites in which you feel that you are staying in a hotel.

Nautilus UnderSea

The UnderSea first entered service in 1968 as the personal submarine tender to Dr. Perry of Perry Oceanographic. We graced the ship with a massive shipyard refit including: stretching the hull out to 105 feet, a new superstructure and extended sun deck, a bulbous bow and stability system.

Mango Wind

Our beautiful Leopard 45 sailing catamaran provides a different and intriguing way to experience the Sea of Cortez. Sailing is fun. Sailing is awesome!

Nautilus Westerly

Giving back. At our core, we believe in giving back to Mother Ocean. One of the ways we do this is to make the Westerly available at cost for conservation or science trips around Baja and out to both Socorro and the Islas Marias.
