The duty report appears at every league point and shows how well, or poorly, the pirates on the ship did at their puzzles during the last league. It is visible to puzzling pirates at every league point, and when entering battle. Both puzzlers and non-puzzlers can view the report when they press the escape key or pause/break. The duty report displayed when escape is pressed is the report from the last league, it is not a snapshot of performance at that instant.

Duty reports are displayed in either one or two columns depending on how many pirates are working aboard the vessel. If there is insufficient space to display all the information, a scroll bar on the right side of the window will appear. The duties are always displayed in the following order: Navigating, Sailing, Gunnery, Carpentry, Bilging and finally Treasure Haul. Duties that had no pirates working on them (or in the case of treasure hauling are not applicable at that time) will be omitted from the list entirely.

Duty Report Ratings

The duty report ratings are, in order from worst to best:

• Booched
• Poor
• Fine
• Good
• Excellent
• Incredible

The "Booched" and "Poor" ratings are replaced with a green "Learning" rating for greenies. The same ratings are used when completing a crafting puzzle. Note that these scores are actually textual representations of a numerical score and are sorted as such; this means that it is still possible to determine who is performing best at a duty even if multiple pirates scored an 'Incredible'.
