General description


This vessel is a Wildcat 60 multi purpose survey catamaran. The vessel has a LOA including the substantial aft dive platforms of 18.5m, a beam of 6.2m and a draft of 1.4m. The vessel has a 33,000kg lightship displacement and a loaded displacement of 37,000kg. The design is for an ocean research and hydrographic survey catamaran capable of operating offshore for 7 days duration for 12 crew with ‘all weather capabilities’ able to operate in rough conditions and in S.A.R. roles when required and undertake coastal and offshore ‘Patrol’ duties.


A degree of customization is avilable; the vessel can be sold with or without the dedcated survey equipment (price reduced acordingly) and adapted for differing roles with the incorporation of additional passenger seating or arrangments in the main cabin for patrol, crew transfer or S.A.R. operational roles, see example GA drawings below.

To facilitate her long duration capabilities 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 240V 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 ac 240v domestic washing machine / dryer.  Long duration voyages are made possible by the 800 litre fresh water capacity. A 600 litre black water tank is fitted.


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 Raymarine navigation equipment including 48nm radar & 12” C127 colour display, GPS, plotter on 2nd 12” display, sonar 2x VHF DSC radios, Raymarine autopilot, Raymarine graphic display fishfinder, AIS, 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. AC sockets run along the table top and below, trunking for data cables to the aft deck is provided and data cables run, hatches allow the tempoary running of cables to the sonar deployment system on the aft deck. 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 below with multiple AC outlets and space for computer screens. A second 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. Noise levels are exceptional low (70db) and provide a very relaxed enviroment during passage.

Deck arrangements

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 with 200m of  large 32mm dia electrical data cable and deploying equipment over the transom. 3x spare drums are carried onboard stored on 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 with a 1,000kg SWL 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 2x 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 029 hydraulic slewing knuckle crane which has a maximum lifting capacity of 470kg at 6m reach and a maximum lift of 2,900k

The vessel is fitted with twin Volvo D16 engines and provide the vessel with a 23kts maximum speed @ 1900rpm and an 19-20kts operational cruise speed at 1750rpm with a 75% fuel load. Fuel capacity is 3,500 litres and allow for a 1,400 nautical mile range at displacement survey speeds of 8-9kts.

Onboard 230V AV power is provided by a pair of Fisher Panda ‘I’ series  linked 15kw generators providing a 30kw combined power output of the  i-range variable speed units. These are variable speed units are electronically linked together operating in tandem, only one unit works when under lower loads with the second unit starting only when load demands it, RPM is varied according to load with the units running at faster rpm when full load is needed, the variable speed sets ensure that the engine is always correctly loaded and this in turn delivers really good fuel savings, lighter in weight and size, longer service intervals and extended engine life.

The vessel is suitable for hot climate operations and is fitted with two powerful 27,000btu and one 16,000btu unit,  (70,000btu total) the main and uppercabin roof as well as the lower cabin, under deck roof areas are insulated. A powerfull 500mm dia Axial fan provides forced air into each engine room,  with hot air exhausted through separate mist removal vents.

The survey launch has been built to comply with the UK MCA under 24m workboat requirements, category 0-II


Build standards.

The vessels hull construction has been designed in accordance with Lloyds Special Service Craft rules and regulations for category ‘workboat’ and area of operation ‘G3’

The Hull design has been approved by the Polish Register of Shipping and the M.C.A.

The vessel is built in respect of its machinery and safety equipment  under survey and to the UK’S MCA workboat regulations category II, 60nm offshore and supplied with an MCA workboat certificate on delivery. A Polish Resister of Shipping hull survey certificate will be supplied.




The Wildcat has been designed from the beginning to combine safe dependable sea keeping and stability with performance and economy. The Wildcat hull design utilises ‘high buoyancy bows’ incorporating much fuller fwd sections, offering greater buoyancy and giving the hull the necessary lift to prevent slamming on the bridge deck, allowing higher speeds to be maintained into larger ocean swells. The hulls are a hybrid design between semi displacement and planning hulls, symmetrical multi chine in form. The main chine deflects water out and away from the hulls having a two-fold effect. On the outboard chine this improves ride dryness and reduces wetted area. On the inboard chine the spray is turned so that in waves it provides a cushion effect. The spray is mixed with air coming down the tunnel and creates a high-density medium, which dampens motions through waves. The likelihood of slamming on the bridge deck is greatly reduced as a result of the hull riding on this high-density spray cushion. A second chine situated 400mm higher than the main chine and further aids in boat dryness, especially at lower speeds when the main chine is mainly immersed.

The vessels beam has been constrained to a wide 6.3m, providing a good compromise between work area, stability, and minimal slamming that tends occurs on catamarans that have an excessively wide bridge deck. Also marina space and berthing facilities are considered, where excessive beam can be hard to facilitate.

Due to the relatively slender nature of the Wildcat’s hulls, in choppy conditions vertical accelerations are much reduced in comparison with a mono hull’s, giving a gentle ride and motion. In following seas the Catamaran has a distinct advantage, the twin hulls form a ‘grove’ in the water allowing the hull to track as if on rails whilst the tremendous transverse stability means the hull suffers little yaw and surge, especially in quartering seas allowing virtually  ‘hands off steering’ and zero broaching tendencies, even in extreme conditions and as such the Wildcat 60 is suitable for Search and Rescue operations in rough weather conditions.

The WILDCAT has been operated safely in up to force 9 sea conditions

The vessel lends itself to surveying roles, under normal survey operations the catamaran has much better directional stability than a monohull resulting in less effort and fatigue for the helmsman, which ultimately improves survey data. The reduced vessel motions in heel and yaw result in accurate data recording as does the ability to site the multi beam surveying sonar equipment almost exactly on the vessels transverse and longditudal centre of gravity.

Sea trial / performace data

The Wildcat 60 posses very high levels of seakeeping abilities and stability and is capable of operating in rough weather conditions. Below, photos during sea trials in Force 9 conditions and 7m waves.
