CAIRNS CITY WATER ACTIVITIES FIELD GUIDE
Sail to Thetford Reef: 2 Days, 1 Night on the Great Barrier Reef Liveaboard
A 2-day, 1-night (32-hour) liveaboard aboard the 66-foot Rum Runner from Cairns offering snorkel and scuba dives on outer reefs — this guide distills the itinerary, logistics, and who should go.
Sail to Thetford Reef: 2 Days, 1 Night on the Great Barrier Reef Liveaboard.
This is a compact liveaboard that delivers concentrated reef time: depart Cairns on the Rum Runner for roughly 32 hours at sea, reach the outer reefs (notably Thetford Reef) for multiple snorkel and dive sessions including a night dive, then return to Cairns the following afternoon. The trip focuses on accessible, hands-on diving and snorkeling across varied reef sites while operating from a working 66-foot motor-sailing schooner.
Highlights
Outing Highlights
Outer-reef immersion at Thetford Reef
The vessel aims to reach Thetford Reef by midmorning where guests spend the day and night diving and snorkeling; sites span shallow coral gardens to pinnacles, caverns, swim-throughs and walls, with diving tailored to experience level.
Rum Runner — a compact, working schooner
The Rum Runner is a 66-foot motor-sailing schooner with a fiberglass hull that accommodates up to 16 guests in twin and four-share cabins; common areas include a dining space and covered and open decks, but cabins are modest and designed for rest rather than luxury.
Multiple dives including a night dive
The program includes multiple day dives and snorkel sessions and a scheduled night dive; certified divers can do up to six dives over the trip, while introductory dive packages include two full introductory dives.
What the day feels like
What the trip feels like
You meet at the Rum Runner berth in Marlin Marina early, help stow kit and get briefed, then sail out to the outer reef. Days are structured around dives and snorkel sessions at distinct reef features such as lagoons, coral gardens and swim-throughs; evenings are relaxed—dinner at sunset, a night dive for certified divers and anchored moorings for a quiet night under the stars. The second morning brings more dives and a final lunch before the short sail back to Cairns.
