Turbine Fast Ferry
J&A did the acoustic design for the turbine-powered, fast catamaran
ferry delivered by Derecktor Shipyard in 1998. The challenge was
to design ferry that was comfortably quiet for its customers with
sound proofing that was light weight enough to minimally impact
the high speed capabilities of the ferry. The vessel met the acoustic
design predictions from J&A. (Noise level at 48 knots in the
main deck passenger compartment averaged 71 dB(A).) Click here

Ferry - 73M
J&A is the acoustic designer for a 73 meter fast ferry, diesel.
The boat is only a 33 knot vessel, but there are severe weight penalties
and weight savings rewards which are reflected in J&A's insulation
