1.3.1 Masthead Unit
The Masthead Unit senses apparent wind speed and wind angle. The unit is
light weight and sealed.
1.3.2
Paddle Wheel
The Paddle Wheel Speed Sensor is designed primarily for cruising yachts
and consists of a paddle wheel that protrudes through the hull via a housing.
So that the paddle wheel may be cleaned at regular intervals the housing is
provided with a flap valve that closes automatically when the unit is pulled
back into the yacht.
1.3.3
Sonic Speed Unit
The Sonic Speed Unit provides highly accurate and stable boat speed
measurement. It does not rely on mechanical moving parts that require
constant attention to protect them from weed, etc. The transducers are fitted
virtually flush with the hull, creating almost zero drag, and can be painted,
faired or anti-fouled.
1.3.4
Depth Sensor
This can either be a removable through-hull unit, or moulded in-hull for
reduced drag. The depth datum can be set to the waterline, the bottom of the
keel or from the transducer.
1.3.5
Super Halcyon 3 Fluxgate Compass
This fluxgate compass sensor is fully gimballed in a bath of oil, ensuring
accurate readings at all normal angles of heel and pitch. The unit features
automatic deviation correction, thus eliminating the need for expert compass
adjustment.
1.3.6
Halcyon 2000 Compass
The Halcyon 2000 Compass is a high performance electronic fluxgate
compass for use on both sailing and power craft. It is intended to be
connected to Hercules 2000, Hydra 2000 or HS 2000 instrument systems
through the B&G Fastnet Network.
