Unit 1 was traveling SW on Channel Lake. Unit 2 was traveling due East on Channel Lake. 

Unit 1 did not yield to unit 2 and collided into unit 2's port side, just to the Aft of mid-vessel with it's front starboard coroner. Both vessels came to rest, upright with both facing east. 

Unit 2 said unit 1 didnt stop as he was crossing in front of me and I even went into reverse to try to stop.
