Certified Diving with Poseidon CruisesOuter Reef Day Cruise

Designed for personalised dive and snorkel adventures, the modern 24 metre dive catamaran Poseidon, departs daily from Port Douglas to visit 3 different and unique reef environments. With over 35 spectacular and exclusive reef sites at the Agincourt ribbon reefs and Escape Reef, Poseidon can offer some of the very best day boat diving. 

Sites are selected daily to suit the day's conditions and to maximise experiences. With a separate dive tender to assist with drift and wall diving, this is a day well suited to experienced divers and snorkellers. 

The clear outer reef waters, beautiful corals and incredible marine life diversity of the Agincourt ribbon reefs offer the opportunity to snorkel and dive in some of the most pristine and special places on the entire Great Barrier Reef. Enjoy unlimited snorkelling in this marine wilderness, first time divers can try an introductory scuba dive, and certified divers can experience up to three dives.

Poseidon has limited passenger numbers to ensure personalised service and attention. Whether you choose to snorkel or dive, with an amazing array of quality reef sites, attentive and friendly crew, the comforts aboard and our special permit to swim with the Dwarf Minke Whales, Poseidon offers you the perfect setting to enjoy a day on the Great Barrier Reef.
