RedactedNarrative: Two vessels were traveling north in the ICW when one vessel made a sharp turn resulting in another vessel colliding into it.
  On 2/19/2018 two vessels traveling north at approximately 30-40 mph collided after the lead vessel made a sharp right turn.  The vessels gunwales made contact causing damage to both vessels.  The striking vessel owner (Operator1) made contact with the vessel he struck and exchanged information.  The operator of the struck vessel did not have a chief complaint following the incident but did receive small cuts from stepping on broken glass.  The next day Operator2 visited his primary care physician and was told he suffered a concussion and bruising.  The occupant of the struck vessel has not sought medical treatment but complained of pain in his ribs.
  
  I met with the complainant on 2/20/2018 because the accident was reported the day after the incident.  Operator2 stated he was traveling north in the channel when a vessel approached from the rear on his starboard side.  He stated the vessel ramped over his vessel but he was not struck by the vessel.  He claimed the vessel motored off approximately 100 yards away but quickly came back to see if there were any injuries and to assess the damage.  Operator2 stated he felt loopy and "out of it".  He didn't feel he had any injuries at the time.  Vessel damage to V2 consists of minor fiberglass damage to the stern of the vessel, broken glass on the starboard windshield, and damage to the hardware holding the bimini top.  He  also stated his trim motor was not working properly before the incident but is not working anymore.  Operator2 stated he did not contact law enforcement because he thought he didn't have to and reported it the next day because of injuries.
  
  I spoke with the operator of the striking vessel (Operator1) on 2/23/2018.  He stated he and wife and their two friends were traveling north in the ICW approximately 50 yards behind Operator2 when he witnessed Operator2 make a hard right turn.  Operator1 stated he could not avoid colliding with Operator2.  He also said their vessels made contact on his port side and on their starboard side.  Operator1 denied stating that his vessel ramped over the other vessel.  Operator1 stated he spoke to Operator2 after the collision and made sure he was ok.  He stated that Operator2 appeared to be ok and acted normally.  He specifically stated he was "alert and oriented".  Operator1 said he did not contact law enforcement because there appeared to be minimal damage and that there were no apparent injuries.  Damage to Operator1s vessel consists of what appear to be superficial cracks below the deck on the support structure.  The insurance surveyor stated he was unsure if the cracks were severe enough to be repaired. 
  V2 occupant will seek medical treatment for bruised ribs and back.
  Per primary care physician, operator2 sustained bulgings disks in neck and back, sustained lacerations to feet and legs from glass, and a contusion.  Subject to be treated with physical therapy.
