Yanmar Powers Boutique Snorkeling Vessel

Yanmar commercial marine engines have been specified to power the most recent reef snorkelling vessel to arrive into Port Douglas. The new multi-million dollar Wavelength boutique catamaran has a pair of 6 cylinder 13.7litre purpose built commercial marine Yanmar 6HY-WET engines and Yanmar transmissions installed to make sure it able to perform its daily work load with efficiency and reliability.


Designed by Incat Crowther and built by Aluminium Marine in Brisbane, Wavelength is the ninth of ten vessels built by Aluminium Marine and powered by Yanmar over the recent years. This is an exceptional vote of confidence in the Yanmar brand and the quality of their purpose built commercial marine engine packages.
Wavelength Reef Cruises operates a fleet of purpose design vessels catering for small groups of snorkelers. The company is a pioneer of Reef Eco-Tourism and has
carried their commitment to the environment through to the construction of their latest catamaran, this 19m tourist ferry, Wavelength.
Wavelength’s co-owner Jenny Edmondson, said that the company had their new vessel built in Australia with Aluminium Marine, because the boat builder has a fantastic record for quality and engineering.

“With Aluminium Marine we could be involved in the build, to tailor the boat exactly to our requirements and we were able to eco-source the materials and equipment,” Jenny Edmondson said.
“We are operating in a natural wonder on the Great Barrier Reef and we have an obligation and commitment to demonstrate best sustainable practices.”
Their commitment to the environment followed through to the selection of the Yanmar 6HY-WET engines. These engines are IMO Tier 2 compliant, ensuring emissions are exceptionally low.
Yanmar’s 6HY-WET model is a purpose built commercial grade marine engine. It includes Yanmar’s latest combustion chamber design, named ASSIGN, a system originally pioneered by Yanmar on their large bore, low speed propulsion engines.
This technology combined with Yanmar’s own mechanical fuel system delivers impressive fuel consumption results and provides commercial operators with excellent fuel savings.
The Yanmar 6HY-WET as specified by Wavelength Reef Cruises are the 478kW (650mhp) model, a rating which is a perfect selection for those who require their engine to run at full throttle for extended periods. The cylinder head is a quad valve design. In this configuration, the Yanmar 6HY-WET excels in conditions demanding continuous commercial use. The new Wavelength catamaran also features Yanmar heavy duty rated YXH160 hydraulic shift marine transmissions.
With a length overall of 19.56m and beam of 6.0m, Wavelength has a total fuel capacity 2400 litres. Lightships, the top speed is an impressive 29 knots at 2200 rpm, while the service speed is 24.9 knots. In sea trials the hull has proven to be very seaworthy and economical.
Despite her overall size, Wavelength is configured for a passenger capacity of just 50 people. This ensures that there is plenty of room on board for a comfortable and relaxed experience on the Great Barrier Reef.

The proliferation of Yanmar powered catamarans from Aluminium Marine is no coincidence. Yanmar commercial rated marine engines which include the Yanmar 6HY and Yanmar 6AY, have both proven to be an ideal match with Aluminium Marine built catamarans.
“We very much like the Yanmar line of commercial engines,” said Jack Louwerse, Project Manager/Engineer at Aluminium Marine.
“Our experience with the Yanmar 6AY and 6HY series is extensive. From an installation and operational perspective the Yanmar brand is first rate. Our customers are just as enthusiastic as us about the Yanmar engine and speak very
