RedactedNarrative: On March 24th, 2018, responded to a capsized vessel 5 miles south of sombrero beach. Upon arrival the vessel had sank in 35 feet of water and the 3 POB's were safely on a USCG vessel being brought in to the USCG station Marathon. The vessel sank at Coordinates N24. 36.806 W81. 08.206. SeaTow was hired by Captain Pips livery to recover the vessel. 
  
  I interviewed the Captain of the vessel who stated they had trolled a little bit and then had just set anchor from the bow and the boat sank within 5 minutes of them being at anchor. 
  
  Two people both had similar stories stating the water came in from the stern of vessel and that the bilge pumps were working but couldn't keep up with the vessel taking on water. all 3 person were in the water when rescued . 2 of which were wearing PFD. No alcohol was suspected as they had just got out for the day and had all of their drinks and food on ice untouched. The operator did state he had 2 beers when he got on good sam vessel named Tonica. 
  
  The next day I made contact with the livery to inspect the vessel that was recovered. No signs of reason for capsizing was seen. The anchor was tied off from the bow but cut when retrieved. It was stated there was 150 feet or so of anchor line but on 2 feet when inspected due to loss. the ignition key was on and there was a bilge pump on the vessel . The vessel was stored on the water at the dock so there was no structural damage to bottom. When the diver went down to recover the vessel he stated all plugs were in and no sign of what sank the vessel.
