We are thrilled to introduce the latest addition to our boat building and design company, Aquarius II. This bespoke 26 metre aluminium dive catamaran is the perfect vessel for operations based out of Port Douglas, Australia. Our highly trained Thai staff with Australian project management have utilized their skills to construct a vessel of remarkable quality.
Aquarius II has exceeded all expectations, exceeding a high cruising speed at low RPM, running trim was perfect and the hull gave off a relatively low wash. It is powered by twin MTU 8V 2000 (965hp) diesel marine engines and conventional prop/shaft with a top speed of over 30 knots, with a restricted operating speed of 25 knots cruise at 70% load, with amazing fuel burn.
With a semi-displacement deep vee type hull and plumb bow design, the waterline length has been maximized and maintains the measured length of under 24 meters LOA. Not only is the vessel fuel efficient, but it also has an extended range capability for delivery voyages or extended cruising time.
Designed to cater to daily dive charters, Aquarius II is equipped with the latest technology including an inbuilt air compressor and hydraulic (two-stage) dive platform for snorkeling and scuba diving. The aft’ dive deck has four toilets including hot and cold water showers as well as wet suit lockers. Additionally, this vessel is spacious and comfortable, featuring forward walk-around sides on the upper deck with large forward and aft’ lounge decks making it one of the most popular vessels in its class.
