Deja Vu (2006)

Question: Why did Doug did not travel back to the night before his partner was killed? He could save his partner, the girl and the people on the ferry.

Answer: They only have a 4-day window to observe and intervene with the past events. Once Doug and everyone else observed his partner being murdered, the 4-day window for that event had lapsed.

In theory, he could go back (not far enough), then find the time travel scientist, convince him to believe his story, and travel back another 4 days, etc. A lot of ifs, but it could be possible?

He could, yes, but their priority right now is to go back and prevent the ferry attack. They were on the trail of the terrorist at this point, so going back before taking care of that matter could further complicate things.
