Or someone who take Right of Way way, way, too seriously.

I can't believe he didn't see a vessel that big and interesting. It seems
far more likely that he was trying for a close pass ahead and misjudged the
speed or a stern buzz and didn't anticipate the huge airflow disruption a
vessel of this size would create. It looks like he was trying to tack just
before contact. Looks like a hot dogging stunt gone bad.
