Incat Crowther has delivered Wavelength 4, a 19m catamaran tour vessel claimed by its operator to be “the cleanest tour vessel on the Great Barrier Reef”
Built by Aluminium Marine in Queensland, Wavelength 4 features Incat Crowther’s efficient hull form and boasts numerous environmental features. The green approach was practical, focusing on a low environmental cost of producing and operating the vessel rather than emerging technologies.
In addition to the reduction in fuel usage that comes with 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 toll of production was lowered by the implementation of solar power at the yard, local build to reduce delivery distance and use of recyclable materials, in addition to the elimination of anitfouling.
The result of a collaborative development effort between Incat Crowther, Wavelength Cruises and Aluminium Marine, Wavelength 4 aims to create an unparalleled customer experience. This experience starts from the moment the passengers board the vessel, where they are greeted with 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 a two toilets, stairs to the upper deck and the main cabin door. Inside the main cabin, passengers are greeted by a large amenity space, including change rooms, galley and server and photo
station. Forward of this space ids a saloon with 38 lounge seats, in a bright airy and relaxed environment.
Upstairs, the customer experience continues with lounges arranged around the central control position, offering interaction with the captain and commanding forward views. 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 478kW each. She is capable of a maximum speed of 29 knots.
