Encourage (Any Phase)
You can encourage another member of the crew to give her a bonus to her action. This works like aid another (see page 133), granting a +2 bonus to the check required by a crew action if you succeed at a DC 10 check using the same skill. Alternatively, you can grant this same bonus by succeeding at a DC 15 Diplomacy check. You can’t encourage yourself.
