10.4.10 How to reverse sailing order of a route
You can reverse the order of waypoints in a plan route. Put the cursor on Route in the sidebar then click the Plan
button to open the Plan Route dialog box. Click the WPT tab to open the WPT page. Check Enable changes. Click
the Reverse route button.

10.4.11 Geometry check of route
When you add a new waypoint, modify a waypoint or change other waypoint data, the message "Impossible turn at
WPT xx (waypoint no." may appear (in red). It means that the geometry of route makes it impossible for the ship to
sail along a certain leg. Typically it is enough if you do the following, on the WPT page in the Plan Route dialog
box.
WPT xx (waypoint no." may appear (in red). It means that the geometry of route makes it impossible for the ship to
sail along a certain leg. Typically it is enough if you do the following, on the WPT page in the Plan Route dialog
box.
1. Decrease the radius of turn of the waypoint or one of its neighbors.
2. Change lat/lon position of the waypoint or its neighbors.

Optimization
10.5.1 Available route optimization strategies
After all waypoints are inserted, the route is optimized from the Parameters page in the Plan Route dialog box.
Optimization calculates all parameters for route steering (course and distance between two waypoints, maneuvering
start point, WOP, etc.). There are four methods for optimization:

Max Speed:
This calculation uses the maximum speed defined in the ship parameters and multiplies by all reduction factors
(weather, ice, fouling, etc.) together with speed limits given for each waypoint to generate ETA. ETA may be
entered, however it is calculated with user-entered ETD and Speed limit. ETA and ETD are shown on the Monitor
display.

Time Table:
Calculates the speed required in order to arrive at destination at required ETA. Maximum speed is never exceeded.
The user enters ETD and ETA to calculate speed to use. * If, the user-entered ETA is earlier than that found with the
Max. Speed calculation, the Max. speed -calculated ETA will be indicated below the Time Table ETA calculation
figure.. The calculated speed is shown on the Monitor display as "Suggested **.*kn".

Max. Profit:
Based on ETD, this calculation takes in account the fuel cost and the fixed cost of the ship and calculates the most
profitable speed (highest profit per time unit). You need to set Optimization parameters beforehand to use this
feature. For further details, see section 19.1.4 Optimization parameters setting.

Min. Cost:
Based on ETD, this calculation takes in account the fuel cost and the fixed cost of the ship and calculates the speed
that gives the minimum total cost. You need to set Optimization parameters beforehand to use this feature. For
further details, see section 19.1.4 Optimization parameters setting.
