Optimization is designed for Operators to add voyage-specific parameters, such as timing or fuel constraints, as well as updated market factors. Please use this feature at the start of every voyage (or when updates are required) to ensure a vessel's information is up to date.
Please note, depending on your preferred operating procedure, the Optimization tab can be made uneditable by captain accounts. In this case, operators will enter these parameters for the vessel, and captain accounts will only be able to view them.
Standard and ECA fuel cost and opportunity cost will remain from one voyage to the next if there are no changes made. Note: Only Operator accounts can view Market Factors; these are not visible for Captain accounts.

This will take into account the calibrated vessel performance and the weather along the route to provide the vessel with a dynamic optimal RPM setting daily to ensure the vessel arrives before, at or within the Required Time of Arrival.
When to set: Only when voyage orders, Laycan or Charter Party agreement require a strict arrival time.

On: Arrive on specified date and time in UTC.
Before: If set to before, Wayfinder will provide speed guidance so that your vessel arrives prior to the date and time.
After: If set to after, Wayfinder will ensure guidance does not route your vessel to port before the specified date and time. For example, if your vessel must sail for two weeks as part of a COVID-19 quarantine procedure, you could set the RTA to after the start of the quarantine end time.
Between: Please use the between option if you would like your vessel to arrive within a specified date range. For example, if you would like your vessel to arrive in a specified tidal window.
