Narrative:

We experienced course deviation due to the PF's lack of attention. There were no conflicts or mishaps. I realize on long flts without autoplts, it can be very boring. The only way to solve this problem in the short term is to remain vigilant as much as possible. I called out course deviation a couple of times, but I'm not sure if it registered or not. We corrected the problem by flying to the course and trying to remain alert as possible for the rest of the flight.
