Minimum safe vessel depth
As part of the Initial startup wizard the Minimum
Safe Depth value can be set.
Minimum Safe Depth can be established by adding
together:
• Maximum Vessel Draft (i.e. the distance from the
waterline to the lowest point of a vessel’s keel.)
• Safety Margin (an adequate clearance below the
keel to allow for draft variation and changes in
water or bottom conditions.)
i.e.: Minimum Safe Depth = Maximum Vessel Draft
+ Safety Margin.

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 how much a
vessel draws are shown below:
• Vessel displacement (weight) — A vessel’s draft
will increase when it is fully laden when compared
with its unladen displacement.
• Water type — A vessel’s draft will increase 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 draft increases due to squat, trim, roll,
pitch and heave.
• Chart accuracy — The electronic chart depth
may not be accurate or the true depth may have
changed since the last survey.
• Weather conditions — High air pressure, and
prevailing wind strength and direction can affect
wave height.
Warning: Minimum Safe Depth
The Minimum Safe Depth setting is
used during Autorouting to restrict the
created route from entering water that is
to shallow for the vessel.
Bottom depth is taken from compatible
electronic navigational charts and
Minimum Safe Depth is a user
calculation. As both of these factors
are outside of Raymarine’s control,
Raymarine will not be held liable for any
damage, physical or otherwise, resulting
from the use of the
Autorouting feature
or the Minimum Safe Depth setting.

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
