This design is for an ocean research and hydrographic survey catamaran capable of operating offshore for 7 days duration for 12 crew.This vessel is a Wildcat 60 / 19m catamaran. The vessel has a LOA including the substantial aft dive platforms of 19m, a beam of 6.2m and a draft of 1.4m. The vessel has a 31,000kg lightship displacement and a loaded displacement of 36,000kg. To facilitate extended duration voyages this the vessel has two sleeping cabins, one in the lower port hull and one in the st/bd hull, each fitted with 6x bunk berths and each cabin with its own separate heads compartment. A full galley is positioned in the f/wd port hull and is equipped for extended sea operations, fitted with a large capacity fridge freezer, dishwasher, 240v hob and microwave, large worktop areas and storage. A third large heads and shower compartment is positioned in the st/bd f/wd cabin and here is incorporated multiple storage lockers and a washing machine / dryer. Long duration voyages are made possible by the integration of a watermaker converting up to 1,300 litres of salt water into fresh water and supplemented by a 800 litre fresh water capacity. A 600 litre black water tank is fitted.

Interior
The main cabin is a twin deck arrangement with a raised steering and navigation position. Seating is provided for a helmsman and navigator, both on shock mitigation suspension seating, with 2x additional bench seats either side. The raised position allows excellent all round visibility and control of the vessel with a full suite of navigation equipment including 48nm radar, GPS, plotter, sonar VHF, autopilot etc, all flush mounted in a large helm console. The main cabin incorporates two areas, the f/wd area houses the main hydrographic work area, incorporating a U shaped worktop with computer racking below, space for multiple computer screens and is fitted with three fixed seats. A dinette area with settee and table is positioned opposite. The aft area houses an additional survey work area with work table, twin fixed seats and computer racking. A settee area with table is positioned here as well. A server room is positioned in this area, and is fully air conditioned by a 16,000btu air con unit. A 2m high server rack is incorporated in the server room. The overall design of the accommodation allows up to 12 crew to operate from the vessel in comfort.
Engineering
The deck arrangement has an ‘island’ cabin configuration with easy access around the vessel protected by high bulwarks and railings allowing safe operation on deck. Access to the raised foredeck is by twin steps port and st/bd with the area protected by railings all round. The aft deck is specially designed for hydrographic and survey operations. A large moon poll of 1.5m x 1.3m is fitted with a hydraulically operated multibeam deployment system capable of raising and lowering transducers and equipment up to 1,000kg in weight to below the keel level. A large 1.5m diameter tension drum of 1,000kg pull capacity and is capable of being pre loaded with200m of large 32mm dia electrical data cable and deploying equipment over the transom. 3x spare drums are carried onboard stored on the aft deck or the cabin roof and can be interchanged on the winch when required. The transom is fitted with a wide central gate allowing access over the transom and is fitted with a tilting ‘A’ frame hydraulically operated by two large hydraulic cylinders allowing equipment to be lifted off deck and lowered over the transom. The transom is fitted with twin substantial dive platforms accessed from their own ladders allowing access to the waterline to assist equipment deployment and recovery as well as dive operations. Additional means of deploying multiple sonar and hydrographic equipment is provided by 4x swing down 4” diameter aluminium transducer poles on substantial gunwale mounted bearings which lock into place securely when lowered and position the transducer below keel level. They are raised and lowered by manual winch. The deck is serviced by a powerful HIAB 077 hydraulic slewing knuckle crane which has a maximum lifting capacity of 470kg at 11m reach and a maximum lift of 2,900kg. A 4.5m RIB can be carried aboard and capable of being deployed and recovered by the crane and stowed on the cabin roof on a cradle.
