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.
The 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.
