RedactedNarrative: Vessel 1 was anchored & fishing.  They saw vessel #2 launch make a loop around the lake, and went back to the ramp to pick up passengers.  When they departed again, they began driving directly at vessel #1; the only other vessel on the water.  When vessel 2 was within 100 yards of vessel 1, operator 1 stood up and tried to wave operator 2 off, but they collided and vessel 2 "ramped" vessel 1.  Operator 2 admits to being distracted by showing something to a passenger and not keeping a proper look out.  Operator 1 said operator 2 smelled of alcohol, but the responding officer did not arrive in time to address the issue.
