The Davidson
Laboratory com-
bines experimen-
tal and numerical
methods to solve
complex prob-
lems related to
surface and sub-
surface vessel
dynamics. The
experimental facilities include a high speed towing tank
with wave generation capability and a rotating arm tank.
The laboratory has tested hydrodynamic scale models of
all types of craft (sail boats, yachts, planing craft, sea-
planes, submarines, torpedoes) to assess their performance
for calm water resistance, propulsion, seakeeping and
maneuvering. Numerical modeling using advanced CFD
codes is performed and provides an excellent supporting
tool to our experimental towing tank.

Viperfish MSX (Marine Spec. Xtreme): Designed for
top side applications, the Viperfish MSX is a high per-
formance shock and vibration proof digital recorder that
converts analog video to digital format. It records high
resolution video (720 x 486 pixels), at full-speed 30
frames per second with zero latency.
Viperfish Amphibian: Designed for intense environ-
ments, the Viperfish Amphibian is a ruggedized all-weath-
er, digital video recorder. Viperfish Amphibian converts
analog signals to digital format and records non-multi-
plexed video up to 640 x 480 pixels to a high capacity
hard drive.
Viperfish Deep: Record high resolution video at depths
up to 1,000 feet on a rugged digital platform. Clear, real-
time, full-speed, non-multiplexed video is recorded to a
rugged hard drive. This battery operated submersible dig-
ital recorder is power self sufficient providing flexibility
and reliability for all your underwater recording needs. It
converts analog video to digital format storing it at 720 X
480 frames full speed 30 FPS.
To ensure top security of data, tampering, jamming and
eavesdropping - Viperfish Amphibian wireless transmis-
sion option frequency hops at 110 times per second at a
minimum of 6 mega hertz per hop. Data is encrypted
with forward error correction. The frequency range is 902
to 928 band (approximately 104 channels). Viperfish high
resolution recorders are ideal for marine research or
underwater applications.
