NavNet system
MaxSea-NavNet Overview
The MaxSea-NavNet is capable of combining and analysing data from multiple sources in real-time. Fully integrated into the NavNet system through a Ethernet network, MaxSea-NavNet facilitates the complete integration between the PC and the NavNet network, sharing information from the radar, GPS, echo sounder and other nav data within the NavNet system.
Full controllability of the NavNet.
The MaxSea-NavNet takes full control of the NavNet display, such as radar range, gain/STC control, Echo sounder range, etc., in addition to handing the navigation data to display in a diverse range of formats.
MaxSea-NavNet Radar Overlay
MaxSea-NavNet provides the highest quality electronic charts available as the basis for its radar overlay. The range of color and transparency of the overlay guarantees that the chart is not hidden.
MaxSea-NavNet overlays the full radar image at the same scale and create an improvement in accuracy and clarity. This allows for the confirmation of precise positioning relative to the chart and clearly reveals any inconsistencies.

MaxSea-NavNet Depth Profile Windows
MaxSea-NavNet provides a fully integration of Echosounder display. With connection of the optional Network Sounder you can show video sounder High Frequency or Low Frequency echogram in various display modes from which to choose. Furthermore graphs can be overlayed in this windows such as Echogram, Temperature Graph, Forward Looking Depth Profile and a Depth Profile Outline.

GPS on the chart
Your GPS on the chart
The GPS/vessel symbol is drawn in each open chart window that contains the vessel’s position. It indicates the boat position displayed on the chart at the point currently indicated by the GPS system connected to the PC. Your GPS on the chart has properties and they must be properly configurated. Following paragraphs provide information on adjustments to your boat properties as needed:
1.Drift and surface speed vector
2.Vector direction display
3.Security Circle & HDOP
4.Waypoint Auto-Scale function
5."Out of limits" positioned
6.Man overboard function
7.Use the Dead Reckoning Function to Make a Test Route
Ground speed, Surface speed and Drift vectors
If you have a GPS connected, MaxSea can display the Ground heading vector on the chart. If you have additional equipment (heading, Speed through water, ...) MaxSea will display Surface speed vector and Drift vector in addition to the Ground Speed vector.
To display and modify vectors, select [Option: GPS/Track...] from the [Utilities] menu.
Select the "Misc" to call up the window zone in which you choose the "Vector direction display" option
•Select "Vector direction display" option
•Select corresponding Heading and Speed in the " Data Input/Output Settings Configuration".

Vectors display
Go to the [Utilities] menu and select [Option: GPS/Track] to choose which drawing vector you want to display on the chart.
Then check on or one of each corresponding boxes.
• Blue vector :
A Surface speed vector is displayed on top of the chart
• Yellow vector :
A Drift vector is displayed on top of the chart
• Red vector :
A Ground speed vector

2.Click the Misc tab for calling up the appropriate window zone.
3.At any time, you can check or uncheck a Direction depending on your choice (displaying The Ground Heading and/or Surface heading and/or Drift vector)
Then choose its display mode, depending on speed variation or not:
1.Choose Fixed Length and enter on keyboard a fixed value.
2.Or choose Speed % variable and enter a limit value.
Security Circle & HDOP
The GPS Centering circle "Radius" and "HDOP" displays are accessed under the "GPS/Track" window. To define the parameters go to the [Utilities] menu and choose [Options: GPS/Track...].
Security circle option
Select the "Misc" tab
Then check the Security circle box to validate the display, and enter a radius circle value.
The display includes 3 parts:
•The distance circle.
•A cone of 15°.
•A segment at GPS position, Segment length is equal to HDOP.
Note: if HDOP is smaller than the boat length, then the segment is equal to the boat length.
HDOP display on the chart shows you the estimated precision of the GPS.
Notes :
(1)- Cone base width depends on HDOP (Horizontal Dilution Of Position) if it is acquired from GPS.
(2)- Cone base width depends on the Mobile width if it is not acquired from the GPS.
Changing when switching waypoints
When you arrive to a waypoint on a route, you can switch to the next waypoint by one of the three methods below.
27
MaxSea Operator Manual version 12.6
PERPENDICULAR and DISTANCE:
Automatically switches the destination waypoint when the boat comes passes an imaginary perpendicular line passing through the center of the destination waypoint and when the boat comes within the arrival alarm range together.
PERPENDICULAR:
Automatically switches the destination waypoint when the boat comes passes an imaginary perpendicular line passing through the center of the destination waypoint.
DISTANCE:
Destination waypoint is automatically switched when the boat comes within the arrival alarm range. For how to set the arrival alarm, see related topic: Security Circle & HDOP.
Waypoint switched at a point (1) of an imaginary perpendicular line.
Waypoint switched at the Arrival alarm circle point (1).
Automatic waypoint switching methods
Activating the automatic waypoint switching method:
Select the [Option:Route] option from the [Route] menu to call the dialog which allows you to activate the Automatic Waypoint Switching method. Distance and Perpendicular are selected ON by default.
Choosing and modifying a switching method for each waypoint.
1.Right click a leg in the planning route and choose "Properties" for displaying its Properties dialog.
2.Click in the empty field according to the "Passage Mode" cell,
3.Choose a mode between Perpendicular or Distance or Perpendicular +Distance.
Waypoint Auto-Scale function
The Waypoint Auto Scale function allows the software to automatically change the chart scale. Change of scale occurs when the boat gets into the Waypoint arrival circle.
