Wesmar (Western Marine Electronics) has introduced a new high-speed, digitally controlled stabilizer system, that uses a high performing, powerful and efficient digital signal processor and proprietary programming to combine multiple system capabilities.

“This system changes the dynamics of roll fin stabilization by using leading-edge software, superior digital processing and a proprietary gyro to predict behavior,” said Wesmar’s Mechanical Division President, Cary Jones. “The integration of measurement and predictive data significantly advances roll fin stabilization technology.”

Called the Model DSP 4800, the new digital stabilizer, with three axes, provides increased stabilization of vessels in turns and following seas. The new technology adds heave and lift sensing (popular for fuel efficiency on high-speed boats).

The DSP 4800 enhances the value of Wesmar’s legendary lightning fast gyro with control electronics and display that provide 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 the optional lift function will position the fins to lift the hull and lower drag. The GPS interface will permit display of the overall improvement in speed. The GPS interface will also provide slow speed and reverse fin lock, eliminating the requirement for additional electronics or mechanical connections, simplifying installation.

A small controller replaces the control box and runs dual monitors and two control pads, giving remote and full navigator capabilities both in the wheelhouse and from the fly bridge. The new system interfaces with existing VGA monitors, or can be connected to its own dedicated VGA display. Easy access is given to customer adjustable settings for each vessel’s roll characteristics via the touchpad controls. This is done through a code incorporated in the software and is a valuable feature that minimizes operator adjustments.  A digital link to the driver board makes the DSP 4800 immune to RF interference, often a nuisance with marine electronics.

Existing Wesmar stabilizers can be upgraded to the new DSP 4800 system by using existing cables and connectors. Wesmar also offers an upgrade package including cables for electronic retrofits of other stabilizer brands.
