RedactedNarrative: V1 was traveling southbound in Biscayne Bay, outside of Haulover Marina, before making a sharp right-hand turn in front of V2, causing V2 to collide with V1's stern.
  I spoke with PASSENGER, who informed me that she was on vacation from Maryland and rented a charter for a bachelorette party. I asked PASSENGER 2 if she knew where they were so that I could meet up with them. PASSENGER 2 informed me that they were on the west side of Beer Can Island. I then met up with PASSENGER 2 and OPERATOR 2 on my patrol vessel and asked PASSENGER 2 to provide a written statement. PASSENGER 2 and OPERATOR 2 both informed me that the other vessel had turned in front of them at the last minute, causing the collision. PASSENGER 2 showed me a number of pictures, as well as a short video clip that showed both vessels traveling parallel to each other, before OPERATOR 1 made a right-hand turn in front of OPERATOR 2's vessel, failing to yield the right-of-way. OPERATOR 1 can be seen traveling from left to right in front of OPERATOR 2's vessel at a very close distance, before the collision. Per Florida state law and U.S. Coast Guard Code of Federal Regulations, OPERATOR 1's vessel was the give-way vessel and OPERATOR 2's vessel was the stand-on vessel. I asked OPERATOR 2 if the vessel was a charter boat, to which he stated that it was not and that PASSENGER 2 and the other occupants were his friends. This contradicted what PASSENGER 2 told me and wrote in her statement. I then conducted a vessel safety inspection. OPERATOR 2 did not have a Type IV throwable device, visual distress signals, a sound-producing device, or sufficient number of fire extinguishers. I provided PASSENGER 2 and OPERATOR 2 with the incident case number and concluded the stop.
  	Based on my investigation, I found both parties to be at fault for the vessel accident. OPERATOR 1 failed to yield the right-of-way, directly causing the vessel accident. OPERATOR 2 failed to keep a look-out and failed to operate in a prudent manner due to the fact that he was taking pictures of PASSENGER 2 and her friends while at the helm. The accident would not have occurred had both parties adhered to maritime navigational law/rules
