RedactedNarrative: vessel was traveling southbound in the ICW and struck day beacon 163 and knocked it over.
  
  At approx 1302 hours a 40' vessel operated by Operator struck the day beacon numbered163 in the ICW in Indian River County.  Operator hailed the Coast Guard and advised them that the accident had occured.  The marker was knocked over to the water level with a little over a foot remaining above the water line.  I received notice and met the Coast Guard vessel along side the sailboat named "Kailua" at approx. the 197 marked of the ICW in St Lucie County.  The boat had very little damage with only a rail on the bow coming loose from hitting the marker.The rail itself was not damaged but the screws were pulled loose.  No other visable signs of damage were observed. I took Operators information and returned to the damaged marker which was photographed and included in ths report. The USCG Aids to Navigation Team was notified of the missing marker and USCG Sector Miami was notified so that a Notice to Mariners could be issued.  USCG said they would broadcast a Safety Marine Information Broadcast (S.M.I.B.) until the Aids to Navigation Team could replace or put a temporary marker in place of the damaged 163. The informed me that they did not know how much replacing the marker would be but that it would be charged to Operator.
