HELE MAI OPERATING MANUAL
NW Explorations
4H: Electronics
The boat is equipped with extensive electronic equipment, including Icom fixed and portable VHF radios, Raymarine
Radar, an Interphase forward-looking Sonar; Raymarine GPS/Plotters with Raymarine display; conventional and graphic
Raymarine Depth Sounders; a Raymarine Speed Log; a Raymarine Autopilot with control at each helm and a remote
control, and a Raymarine Wind Indicating System. The engines are monitored with a John Deere electronic monitor with
LCD display (See “Engine”). An intercom is also provided. There is a complete stereo system.
The Broadband Express and
Iridium System are for the owner’s use only.
Each unit is provided with a dedicated or shared circuit breaker in the DC power panel; this breaker must be on for the
unit to be used. Then the unit’s own power button must have been depressed or its knob must be also be in the “ON”
mode.
4H1: Electronics: Autopilot
The boat is equipped with a Raymarine Autopilot including a control at each helm
and a remote at the lower helm. The autopilot must be “On” for navigation data to
reach other electronics.
For the unit to operate, be sure the breaker is on in the Power Panel.
Basic operation is simple:
• STANDBY
puts the pilot in the standby mode. When on, the display will
show the pilot’s status “Standby”, and on the bottom the scale shows the
current rudder position port or starboard.
• AUTO
Engages the autopilot to hold the heading that existed when pressed. When engaged, “Auto” appears
above the heading that was set.
• TRACK
Connects the autopilot to the vesel’s navigation system. “Track” appears in the display in front of the
heading called for by the navigation system.
• RESP
Decrease or Increase pilot’s sensitivity by pressing this button then the or buttons.
DO NOT CHANGE
THE RESPONSE!
• MODE
Allows you to use the autopilot for power steering; press the or buttons to select mode.
• RESM
Resume the previous heading.
•
(KNOB) Turn to set a new heading.
A Remote control allows the operator to conveniently operate the autopilot while not at the lower wheel, but on the
settee. It is clipped on the console.
Each display also shows the rudder position on its lower edge; in the picture above, it is about 6 degrees. For full details
on the autopilot, see its Manual.
Maintain a careful lookout when using the autopilot! It is an aid to comfortable cruising, not a replacement for an
aware helmsperson! Remember, you can disengage it quickly simply by pushing “STANDBY”.
4H2: Electronics: Digital Depth Sounder/Knotmeter/Log
There is a
Raymarine
standard depth sounder system at the
pilothouse helm on the overhead electronics panel, with a
repeater on the flybridge and in the master stateroom. It shows
the depth
BELOW THE KEEL
and speed in knots, trip mileage in
nautical miles, water temperature, etc.
It operates at 200 Hz
(see note below in Raymarine graphic depth sounder description
below).
