Important: The information below is provided
for guidance only and is not exhaustive. Some
inuencing factors can be unique to certain vessels
and / or areas of water and may not be listed
below. You should ensure you account for ALL
factors that apply to your current situation when
making calculations.
Some of the factors that can inuence vessel height
are shown below:
• Vessel displacement (weight) — A vessel’s
height (from the waterline) will decrease when
it is fully laden when compared with its unladen
displacement.
• Water type — A vessel’s height will decrease by
approximately 2% to 3% in fresh water compared
to seawater.
Some of the factors that should be taken into account
when calculating a Safety Margin are:
• Vessel maneuvering characteristics — A
vessel’s height changes due to squat, trim, roll,
pitch and heave.
• Chart accuracy — The electronic chart data may
not be accurate or may have changed since the
last survey.
• Weather conditions — Low air pressure, and
prevailing wind strength and direction can affect
water level.
Setting the vessel Minimum Safe
Depth, Beam and Height
From the Homescreen:
1. Select Customize.
2. Select Boat Details.
3. Select Min. Safe Depth, Min. Safe Beam or
Min. Safe Height.
4. Enter your calculated minimum safe settings.
Setting time and date preferences
With the homescreen displayed:
1. Select Customize.
2. Select Time and Date Set-up.
3. Use the Date Format, Time Format, and Local
Time: UTC menu items to set your time and date
preferences.
Data master
Systems containing more than one MFD must have
a designated Data master MFD. The Data master
is the primary MFD in the network, this should be
the MFD that has the connection to the SeaTalk
ng®
/
NMEA 2000 CAN bus network and any other devices
and sources of data in your system. The Data master
bridges the data over the SeaTalk
hs
network to any
compatible networked ‘repeater’ MFDs.
Information shared by the Data master includes:
• Cartography
• Routes and waypoints
• Radar
• Sonar
• Data received from the autopilot, GNSS receiver,
instruments, transducers, the engine and any
other compatible external sources.
Note: Your system may be wired for redundancy
with data connections made to repeat displays.
However these connections will only become
active in the event of a fault and/or reassignment
of the data master.
Note: In an autopilot system which does not
contain a dedicated pilot control head the Data
master also acts as the autopilot controller.
Resolving multiple Data masters
An alarm is triggered if the system detects more
than one Data master. A single Data master display
must be selected before you can use your networked
MFDs.
1. Select OK.
The Data master list is displayed.
2. Select an MFD from the list that you want to
designate as the Data master. This should be
the MFD that is connected to the SeaTalk
ng®
/
NMEA 2000 network.
Important: Devices and data from the SeaTalk
ng®
/ NMEA 2000 network will NOT be available to
networked MFDs, if the designated Data master
is not connected to the SeaTalk
ng®
/ NMEA 2000
network.
