Longreach launch

Sunrise III, the first Longreach power catamaran, takes to the water in Thailand.

30 November 2023


After two years of design, development, and construction, the first of the Longreach power catamarans has taken to the water.

Longreach has released images of Longreach Expedition Sunrise III days after it launched from Ocean Marina in Thailand, as the factory undertakes sea trials and the owners prepare to go cruising.

With a top speed of 20 knots, the boat has the power to get out of bad weather fast, thanks to the twin diesel python shaft drive motors. But at a comfortable cruising speed of 11.5 knots, the displacement hull efficiently slices through the water, consuming just 2.8 litres per nautical mile, or 31 litres per hour combined, providing a range of approximately 2,000 nautical miles.

The optional 10,000-litre fuel tanks provide a range of over 3,500 nautical miles.


There are just under 5kw of solar panels on the flybridge hardtop powering the 24kw lithium battery bank to help power the boat, including 92,000 BTU of air-conditioning, backed up by a 4.3kw Whisperpower genset.

Sunrise III is the second Longreach hull to launch, and this Expedition version incorporates a unique layout.

The closed-in cockpit features electric windows to easily open or close up the space, with a BBQ grill and cockpit L-shaped lounge with an aft door that slides open and provides access to the Davco aft dinghy platform.

The spacious galley has Corian benchtops and a steam oven, accompanied by a lounge that opens out into the cockpit, and an internal staircase that leads to the flybridge.

The flybridge boasts a large Portuguese-style helm featuring two comfortable bucket seats and an extensive display of Axiom 16-inch Raymarine chart plotters with 3D sonar, radar and AIS, providing easy access to the forward deck.

Those behind the helm can enjoy an air-conditioned entertaining area with a pop-up TV, lounge, wet bar, and access to an aft deck with a Davco crane for lifting dinghies and more.


The master cabin has a king bed and office, with a TV mounted on the bulkhead and plenty of storage.

On the port side forward is the dedicated private ensuite with a separate rain shower, separate vanity, and a freshwater flushing toilet with portholes.

The starboard side enjoys a queen-sized bed with large side windows for natural light and a dedicated bathroom forward. Meanwhile, the aft utility room houses the washer-dryer and general storage.

The port side offers another queen cabin with a more compact shower and toilet combination.
