Tour boat claimed to be cleanest on Great Barrier Reef

AUGUST 20, 2015 – A 19 m catamaran recently delivered by Queensland, Australia, shipyard Aluminum Marine is “the cleanest tour vessel on the Great Barrier Reef,” according to operator Wavelength Cruises.

The Wavelength 4 features designer Incat Crowther’s efficient hull form and its many eco friendly features are the result of a practical design approach, focusing on a low environmental cost of producing and operating the vessel rather than emerging technologies.

In addition to the reduction in fuel usage as a result of the hull form, the vessel utilizes LED lighting and solar panels. The Yanmar engines are Tier 2 rated and among the cleanest burning engines available. The vessel operates on the basis of zero emissions whilst out on the reef, with the generators not required. This is aided by increased natural ventilation.

The environmental impact of producing the vessel was lowered by the implementation of solar power at the yard, local build to reduce delivery distance and use of recyclable materials.

The vessel has a large aft diving deck, complete with a lifting platform. When lowered, this platform provides a safe, stable and comfortable stepped entry into the water.

Forward of the aft deck are two toilets, stairs to the upper deck and the main cabin door. Inside the main cabin, a large amenity space includes changing rooms, galley and server and photo station. Forward of this area is a saloon with 38 lounge seats, in a bright airy and relaxed environment.

Upstairs, lounge seating is arranged around the central control position, offering interaction with the captain and providing forward views. In all, 44 seats are arranged on the upper deck, in a mix of inside, covered and uncovered configurations.

Wavelength 4 is powered by twin Yanmar 6HYM-WET main engines, outputting 478 kW each. She is capable of a maximum speed of 29 knots.
