Full description
Climb aboard the Silversonic catamaran for a full-day cruise to Australia’s renowned Agincourt Reef, a jewel-like ribbon reef on the edge of the Continental Shelf. With daily departures from Port Douglas Marina at 08:30, and a return to Port Douglas Marina at 16:30, experience unsurpassed coral formations, colorful marine life, and exceptional underwater visibility, and snorkel or dive in the company of an experienced dive instructor. The ultramodern 95-foot (29-meter) Silversonic catamaran is custom-designed for small groups of adventure-minded people. You will spend over 5 hours at the reef, visiting 3 different Agincourt ribbon reef sites, each chosen for its visual and ecological diversity.

Certified divers will enjoy up to 3 dives, all guided to maximize your experience. Silversonic features everything you’ll need to experience an underwater world of colorful marine life in safety and comfort, including a state-of-the-art ride control system ensuring a super smooth journey, hydraulic dive and snorkel platforms for easy water access, spacious deck areas, hot freshwater showers, change rooms, and even a licensed bar to share tales of your adventure. As an added bonus during the whale season, Silversonic has one of the few permits available from the Great Barrier Reef Marine Park Authority that allows guests to swim with dwarf Minke whales if encountered – a truly unforgettable experience from July through September.

Great tour. We were picked up at our hotel and taken to the harbor. We were told the ride out to the reef would be very rough and warned in advanced; we could not change dates due to our schedule. Several people got sea sick on the way out to reef and the crew was very helpful with all and make sure everyone felt good. They really warned us to take sea sick pills one our before our return and once again were veer helpful to the few who got sick on the renter. We did 3 sports on the reef, everyone very helpful and the snorkeling was amazing. Would not have missed this event if they told us a hurricane was approaching.

Everything about this trip was incredible! Amazing service. The food was delicious! If you are unsure if you want to scuba dive, you can decide when you get on the boat. They are very safe and go through all the instructions very clearly. The reefs are absolutely beautiful! Highly recommend

It was great, with the only areas needing improvement being the quality of food provided and more kids size wet suits. Other than that the staff were highly professional with great knowledge which they shared with us, the facilities good- the vessel was awesome. The staff had lovely personalities, showing good humour and a love of fun. It was a very enjoyable experience for my sons & I. SilverSonic is highly recommended.
