PART 1 - INTRODUCTION
1.1 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.
1.2 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
Resettable Log
Dead Reckoned Course and Distance
