SYSTEM DESCRIPTION
The Hydra 2000 is a fully integrated instrumentation system that displays
information obtained from various sensors on a choice of displays
positioned throughout the yacht. Information is fed from the sensors to a
Main Processor. From the information gathered by the sensors the Main
Processor distributes information to the various displays via the Fastnet
cable. This allows it to carry out a wide range of functions including dead
reckoning, true wind speed and true wind direction, etc. These functions are
controlled from a Full Function Display (FFD).
A typical system is shown in Figure 1.1 - Typical Hydra 2000 System Block
Diagram.

PROCESSORS
1.2.1
Main Processor Unit
The Main Processor is the heart of the system and can be connected to
sensors that measure the following:
Boat Speed/Log
Depth
Sea Temperature
Air Temperature
Compass Heading
Apparent Wind Speed
Apparent Wind Angle
Ship's Supply Voltage
Heel Angle
Trim Angle
Mast Rotation
Barometric Pressure
Forestay Load
From this information the Main Processor Unit is then able to calculate the
following additional functions:
Average Boat Speed
Velocity Made Good (VMG) upwind/downwind
