Would these three work? I figured they would be roughly balanced, if somewhat diffrent from what you were thinking.
Whiskey Ration: Increase crew stamina by 20%, reduces stamina regen by 15% for as long as it is active.
Double-Quick: Increases Stamina regeneration by 20%, reduces stamina by 15% for as long as it is active.
Rally Cry: Stamina usage is unlimited for 8 seconds, 15s cooldown
