RedactedNarrative: V1 was anchored on the Six Mile reef out of St Lucie inlet. The operator placed a buoy on the anchor line to pull it up. The buoy went down the port side of the vessel, wrapped in the prop and swung the boat around 180 degrees. It then pulled the stern into the water. The vessel was filled with water and the bow was the only part of the vessel floating. A good Samaritan vessel saw the accident happen and pulled the operator and his passenger aboard their vessel. They were able to connect a line to the vessel and safely tow it to Sandsprit park. No injuries were sustained.
