Changing crew during passage

Crew plans do not always stay the same once a trip is underway. Someone may need to step out of the rotation, a new person may need to help, or the watch pattern may need to adapt to changing conditions. In WatchKeeper, crew changes during a passage should be handled carefully so the schedule stays clear and recoverable.

If you need to change the active rotation, start by deciding whether the situation is temporary or structural. For short-term issues, such as someone missing a watch or becoming unavailable for a period, it is usually better to use schedule adjustments like a swap, delay, or unavailable status rather than rebuilding the crew setup. This keeps the base schedule simple and records the change as an override.

If the actual crew list needs to change, use the crew management area to update the roster, then review the active schedule right away. Renaming a crew member is usually straightforward. Adding or removing a crew member has a bigger effect because it can change how future watch slots are calculated. After any roster change, confirm who is currently on watch, who is next, and whether the watch pattern still makes sense for the remaining crew.

Because WatchKeeper rebuilds the live schedule from saved trip data and the current time, crew changes can affect future watch calculations. That is why passage changes should be made deliberately and then checked immediately on the live watch screen.

Best Practices

• Use temporary overrides for temporary problems.
• Change the crew list only when the roster itself has truly changed.
• Review the active and next watch after any crew update.
• Keep the schedule simple enough for tired crew to understand quickly.

A mid-passage crew change should reduce confusion, not create more of it. The clearest approach is usually to make the smallest change that matches the real situation onboard.
