Details and Specifications of Calypso X11

SeaCat Ships are proud to announce the successful completion of “Calypso X11” built at our shipyard in the heart of Asia, Pattaya Thailand. Calypso X11 is a bespoke 26 metre aluminium dive catamaran built for Calypso Reef Charters in Port Douglas Australia.

After completing sea trials, the results for Calypso X11 have been fantastic and exceeded far beyond expectations. A high cruising speed was reached at low RPM, running trim was perfect, plus the hull gave off a relatively low wash. She is powered by twin MTU/Detroit Series 60 (740hp) engines with a top speed of 26-27 knots. Her operating speed is estimated to be around 22-23 knots cruise @ 70% load, with amazing total fuel burn of around 180ltr/hr and 140ltr/hr 20 knots.

Built by our technically trained staff, the hull is a semi-displacement deep vee type and the plumb bow design (to maximize the waterline length) has maintained the measured length under 24metres LOA. She is very fuel efficient, cutting though the water with a great sea keeping motion. Her Large fuel capacity matched with fuel efficient hulls, give extended range capabilities for delivery voyages or in an accommodation version, extended cruising time.

In keeping with the SeaCat moto – ‘redefining speed, comfort and affordability at sea’ this version is one of the most spacious and comfortable vessels to date. Featuring walk around sides on the upper deck with large fwd’ and aft lounge decks. The lower deck features a spacious air conditioned day cabin with aft’ located galley, a servery and refrigeration. The foredeck is the most popular section of the boat and is extremely large with ample space and the capacity to hold up to 50 passengers.

Fully equipped with the latest technology to cater for it’s daily charter to the Great barrier reef, Calypso X11 has a Hydraulic (two stage) dive platform for snorkelling and Scuba Diving. When the platform is lowered down it creates a dive stairwell for easy access and when it is lifted back up, it is clear of the water and allows for high speed cruising and tender support. The aft’ dive deck has four toilets including hot and cold water showers as well as wet suit lockers.

Built in accordance with the NSCV (AMSA) Class 1C, it is licensed to carry 125 divers plus 5 crew criteria, with the structure to Lloyds Register SSC standard for offshore operations. The same design can also be utilized as a ferry to carry 199 passengers in coastal operations.
