New Environmentally Designed Boat ~ Sep 2018

Launched in August 2018 this new Australian built reef boat has had the same focus on minimising environmental footprint as Wavelength 4. She is very slightly larger than Wavelength 4.

Features for Increased Passenger Comfort

Amenities

Wavelength 4 carries up to a maximum of 48 passengers but is certified for 100 offshore. There is seating for 108, so there’s plenty of room. Comfortable air-conditioned saloon with lounge seating and added passive ventilation when moored to allow a quiet boat with no generator noise. Large shaded top deck with comfortable upholstered seating and lounge style open helm area. Sun areas on the aft top deck and bow. Large panoramic windows in the saloon for great views, including forwards to help avoid seasickness. Three toilets.

Ride Comfort

Slim hull forms have a super-fine entry, deep forefoot, round chines, and maximum waterline length for a smoother ride at high speed. High wing deck clearance avoids slamming even in rough conditions. Hydrodynamic stabiliser fins improve tracking, especially downwind in large followings seas.

Water Access

A wide back deck with a lowering transom and swim platform make water access easy.

Speed

A fast boat with a top speed of 29 knots fully loaded, yet extremely fuel efficient at cruising speed which is limited to 25knots (46kph).

Environmental Features

• Minimum carbon footprint of construction was achieved by local build, recyclable materials, and welding with the help of solar electricity (50kW solar system at the boat builder).
• Super-clean modern technology Yanmar engines (IMO Tier 2) with specialised mufflers for noise reduction and optimum turbo performance giving clean fuel burn and peak fuel efficiency.
• Large roof mounted solar panels and smart technology electrical system reduces generator usage.
• Interceptors improve fuel economy and speed.
• Optimised vessel size for coping well with the local sea conditions yet having a small group experience.
• Very low fuel use of approximately 9 litres per passenger. (This emits 21kgs CO2 and is equivalent to about 6 minutes as a domestic airplane passenger. The offset value is about 40 cents, which we add into our reef research fund.)
• No antifouling.
• All LED lighting to reduce electricity use and generator run time.
• Super low emissions at the reef with no water emissions and minimal need to run the generator.
• Well insulated saloon reduces air-conditioning useage.
• Effluent primary treatment tanks plus holding tanks for all blackwater and greywater.
• Eco-sourced furnishings – such as phthalate free high recycled content saftey flooring (made in UK) and phthalate free seat fabric (made in UK).
• High recycled content carpet (made in New Zealand).
• Dual digital scroll technology air conditioners minimise electricity consumption.
• Recessed anodes to reduce drag and improve fuel effeciency.
• New Zealand made commercial refrigeration with high efficiency and neutral blown gas insulation.
