RedactedNarrative: On 11/4/16 at approximately 0645AM, US Coast Guard documented vessel 1081743 attempted to overtake US Coast Guard documented vessel 983729 in Lake Okeechobee near Clewiston causing a collison to occur.
  
  I asked the owners to give me a synopsis of the boating accident. I was advised that the owner of Vessel 2, Owner2, was following behind Vessel 1 traveling Northeast in the Okeechobee Waterway in Lake Okeechobee near Clewiston. 
  
  At approximately 0645 AM, Vessel 2 attempted to overtake and pass Vessel 1 on her port side at marker 12 in the Okeechobee Waterway. I was advised that this was a narrow channel. Further, I was advised that at marker 12, the channel curved in a more easterly direction.
  
   The operator of Vessel 2 failed to alert Vessel 1 of his intention to overtake. According to Navigation Rule 34, any vessel intending to overtake a vessel in a narrow channel is required to give 2 prolonged blasts followed by 2 short blasts to indicate a port side pass. 
  
  The operator of Vessel 1, advised me that he was unaware of a vessel attempting to overtake him. While Vessel 1 was shifting her course east due to the easterly shift in the channel, Vessel 2 was attempting to overtake Vessel 1. During the shift in course, the starboard back corner of Vessel 2 make contact with the portside bow of Vessel 1 causing a collision to occur.
