RedactedNarrative: On March 7, 2021, at approximately 1700 hrs, United States Coast Guard (USCG) approached me at Miami Marine Stadium, located in Miami Dade County. The crew onboard the USCG vessel advised that there was a boating accident that occurred in Miami Marine Stadium near my location. They advised it was a personal watercraft vs. a center console vessel. Once on scene, I received witness statements from both operators. According to the witness statements and damage assessed, vessel 1 (V1) was operating at a high rate of speed close to the shoreline, vessel 2 (V2) was undocking from the shoreline. V1 collided with V2's outboard engine, which caused damage to the pwc and vessel. Both operators were uninjured.
