RedactedNarrative: On May 6th, 2018, I was dispatched to a boat accident in the area of Nettles Island, St. Lucie County. Vessel 1 capsized due to equipment failure as water entered the rear of the vessel after a new motor was mounted on the transom. Neither of the two people on board were injured. The vessel was recovered and returned to the owner.SEA-TOW was able to recover the vessel and tow it back to the boat ramp where Operator 1 loaded it on his trailer. I was unable to identify any physical defects in the hull that would cause it to take on water.
