Leave Port Douglas for a high-speed catamaran ride to Agincourt Reef on the Outer Great Barrier Reef. Spend the day snorkeling, watching marine life from a semi-submersible, or trying an introductory dive while enjoying an on-pontoon buffet.
More ways to explore the area's outdoor wonders
You step onto the marina at 9:00 a.m., salt on the air and the high-speed catamaran waiting like a promise of open water. The 90-minute run to Agincourt Reef quickens the pulse—sea spray on your face, the horizon flattening into a band of reef that suddenly breaks the blue. The permanent pontoon is a sheltered hub: staff briefings, a marine-biologist talk, and the hum of guests preparing to slip into the shallows.

Book morning departures
Early check-in at 9:00am reduces exposure to afternoon seas and gives you the calmest water and best visibility for snorkeling.
Use reef-safe sunscreen
The operator provides lycra suits, but apply reef-safe sunscreen before boarding to protect coral and prevent repeated reapplication in the water.
Respect dive medicals
Complete the pre-dive health questionnaire honestly—certain conditions or recent flights can disqualify you for safety reasons.
