ships is aligned to the values function- ality, durability, and cost-efficiency. For this, Fintry combined the tried-and- tested catamaran design with a sandwich structure made of carbon fibres. Fintry Two, which was delivered in


February 2007, has a length of 19.95m, a beam of 6.72m, a cross deck height of 1.30m, and a hull draught of 0.70m. Te vessel has an empty displacement of 17.0tonnes and a full displacement of 20.0tonnes. The craft has been fitted with two


368kW Volvo Penta Diesel D12-500 main engines, as well as a ZF 500V propeller, and can reach speeds of 29knots with fuel consumption per machine less than 7litres/nm. Te sandwich structure consists of two


load-bearing layers that are supported on a core material. This increases the stability of the construction. Another advantage of the design is the light weight of the material; compared to aluminium, this construction is up to 35% lighter. Te long hulls of Fintry Two and its light weight mean that the energy require- ments of the ship are minimal, particu- larly at high speed. Since the vessel was built as a prototype


the original goal of Fintry Marine was not to sell the vessel, but to gain experiences with test drives and charters. However, Fintry Two can now be purchased or chartered.


Functional and comfortable Each hull of the pilot catamaran is structured in six watertight segments. In the stern of each hull, there are the fire-resistant isolated enginerooms where two diesel engines, each with an output of 368kW, power the ship. Te large distance between the two drives means that the

catamaran can be moved quickly and easily in port, too. Each hull of the pilot ship is equipped


with two adjacent crossovers. A new fender system – with a particularly broad fender on each hull – permits the safe transfer of the pilots at a speed of up to 15knots. The fender material has extremely low friction and is very robust. Spacious conditions and the f lat,


high-lying deck offer the pilots comfort and at the front, in the centre of the cabin, there is a raised one-man helmstand with a second seat for another member of crew.


Fintry-Brødrene Fintry Marine has also further improved its pilot catamaran in cooperation with the Brødrene shipyard, in Norway. Aſter various pilot associations tested Fintry Two, the results were incorporated into the development of the new generation of ships. Te new design is a lightweight and robust pilot transfer boat, known as the 18m Fintry-Brødrene pilot vessel. Tere are currently no orders for this new design. The new ship is faster, and at 2m


shorter, possesses better characteristics at sea than its predecessor. It offers space for 12 passengers, plus two crew. It has a length wl of 17.25m, a beam of 7.20m, a propeller draught of 1.10m, and a cross


deck height (top) of 2.25m. Two alternatives are now available


for powering the boat – either by two Servogear CP propellers or two Hamilton HM series waterjets. In addition, the new design is equipped with two SP 55 bow thrusters of 50kW each. Furthermore, MARINTEK has


succeeded in optimising the catama- ran hull in a tank test. Te innovative composite structure design is retained but the quality of the new vessel has been significantly improved by carbon sandwich technology and optimisation of the hull lines in the tank test. The improvement of the running character- istics, the reduction in weight, and the proven technology concept thus form the economic basis of the new 18m pilot vessel. The pilots’ comfort has also been


improved with more space in the cabin and the high, flat deck. The catamaran is equipped with a


solid fender strip that runs around the entire boat and a robust fixed fender midships. The fender is particularly wide and consequently enables the pilot vessel to come alongside and leave moving ships even when they are travel- ling at high speed (15knots-18knots). The distance between the two engines means that the pilot transfer catamaran can also be moved quickly and easily in port. SBI
