times per second to pre-empt boat rolls.
The three models are DSP4801, 4802 and 4803.
The DSP4801 standard stabilisation controls roll and
heave, and includes on-screen display of fin movement
in real time. The DSP4802 digital stabilisation and lift
maintains the fin in a positive lift position during all
stabilisation movement, providing maximum fuel
savings. The DSP4803 digital stabilisation, lift and at
anchor, monitors incoming swells and automatically
controls fin movement to reduce the effect.
The Wesmar system displays a real-time presentation
of the fin position and the actual roll rate of the vessel.
Also built-in is the ability to monitor the hydraulic
system for high temperature and low oil level conditions.
For high speed vessels, an optional lift function positions
the fins to lift the hull and lower drag. A GPS interface
permits display of the overall improvement in speed. The
GPS interface provides slow speed and reverse fin lock,
eliminating the requirement for additional electronics or
mechanical connections, and simplifying installation.
