Pilot boat, project 3274

The boat design uses modern technical solutions to ensure its high performance.
The “Wave Length” hull shape, developed at the University of Newcastle (UK) and tested in an experimental pool, is a catamaran with “deep V” hull lines. This hull design makes it possible to eliminate large wake wave (which is important when driving at speed within the city) and reduce drag while maintaining good sailing characteristics.
Thanks to the reduced weight of the hull (made of marine aluminum) and optimized forms, the boat reaches a speed of 22 knots (40 km/h) with a total power plant power of only 420 hp, which ensures economical operation and reduction of harmful emissions.
A low main deck with a railing, as well as a high forecastle with a wide bow platform ensure convenient embarking/disembarking of pilots both on board the vessel and on city embankments and berths.
At the stern of the vessel there is a working deck with a winch, and at the end of the stern there is a tiltable A-shaped cargo frame, which allows you to work with buoys and/or provide underwater technical work. To ensure diving operations, a removable stern ladder is installed.
When the vessel is equipped with appropriate equipment, hydrographic and surveying work can be carried out.
The low air draught (3,5 m from the water to the fixed parts on the deckhouse roof) and the tiltable mast allow it to pass under all Nevsky Bridges.
The wheelhouse contains a control post, a wardroom (with crew rest areas), a galley, a latrine and ergonomic chairs for 10-12 special personnel.
