Important: The information below is provided
for guidance only and is not exhaustive. Some
influencing 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 influence 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

3. Select Min. Safe Depth , Min. Safe Beam or
Min. Safe Height .
4. Enter your calculated minimum safe settings.

3. Use the Date Format , Time Format , and Local
Time: UTC menu items to set your time and date
preferences.
Data master
Any system containing more than one networked
multifunction display must have a designated data
master.
The data master is the display which serves as a
primary source of data for all displays, it also handles
all external sources of information. For example
the displays may require heading information from
the autopilot and GPS systems, usually received
through a SeaTalk
ng or NMEA connection. The data
master is the display to which the SeaTalk, NMEA
and any other data connections are made, it then
bridges the data to the SeaTalk
hs network and any
compatible repeat displays. Information shared by
the data master includes:
• Cartography
• Routes and waypoints
• Radar
• Sonar
• Data received from the autopilot, instruments, the
engine and other external sources.
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.
In an autopilot system which does not contain a
dedicated pilot control head the Data master also
acts as the control for the autopilot.
Designating the data master
For systems with 2 or more displays the following
task must be performed on the multifunction display
that you want to designate as the data master.
With the homescreen displayed:
1. Select
Set-up .
2. Select Maintenance .
3. Select Data Master .
4. Select the display that you want to designate as
the data master.
