"Unlimited" is a 25m catamaran offshore support boat built for Offshore Unlimited at the Richardson Devine Marine facility in Hobart, Tasmania.

The design is based on Incat Crowther’s recent successes in catamaran workboat design, utilising their high carrying capacity hullforms and capitalising on their experience to develop durable aluminium structures.

"Unlimited" is a high speed catamaran workboat capable of carrying 50 tonnes of deadweight with a service speed of 26 knots. The main deck has a carrying capacity of 24 tonnes, arranged for multiple uses and includes a moonpool for exploration services and the ability to carry a 20ft container. The deck is serviced by a Heila deck crane capable of lifting 3.5 tonnes, a remote release tow hook with a 15 tonne SWL and a 2 tonne SWL capstain.

The main accommodation is located forward and contains space for a crew of 12. The main deck cabin houses the galley and crew mess area, along with two crew cabins for the senior crew. Wash facilities are also located on this deck, one accommodating laundry facilities. Junior crew cabins are located in both the port and starboard hull with a large pantry located aft in the port hull. Day accommodation and seating is provided for up to 38 persons.

The wheelhouse is located on the upper deck and features all round visibility from the helm seat. Crew and passenger seating is provided around the perimeter of the cabin. Two wing control stations are fitted forward on either side with a tender/rescue boat located aft within easy reach of the deck crane. The latest electronic navigation aids, a full GMDSS compliant ship radio station, along with Inmarsat Fleet broadband and Iridium Openport satellite communcation systems are fitted.

Powered by twin Caterpillar C32s each producing 1,300hp, the vessel has a service speed of 26 knots at half load. The vessel has an extended range of 1,875nm at 22 knots due to two large 12,500 litre fuel tanks. Unlimited is in USL 2A survey to 600nms from the Australian coast.

Unlimited has been in service since January 2009. For more information about Unlimited, please view the video at the bottom of this page. You can also download the Unlimited brochure and specification sheet.
