12.  ROUTES

7. Click the [<<] button to insert the waypoint(s) from the inactive route to the active 

route. In the example below, WPT1 of the inactive route is inserted at the end of 
the active route, becoming its waypoint 5.

8. Click the [OK] button to finish.

After all waypoints are inserted, the route is optimized from the [Optimize] page in the 
[Route Plan] dialog box. If no optimization strategy is selected, the optimization is 
done with "max. speed," defined in ship parameters. Optimization calculates all pa-
rameters for route steering (course and distance between two waypoints, maneuver-
ing start point, WOP, etc.). There are four methods for optimization:

[MAX speed]: This calculation uses the maximum speed defined in the ship parame-
ters 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.

[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 [Route Information] box 
as [Plan Speed].

[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).

[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 [Cost Parameters] beforehand to use this feature.
