RedactedNarrative: 6/2/19 – Jacksonville, FL 
  One boater believes it was a fragment of the pier that shredded part of his vessel earlier this week. On a boat ride, heading from St. Augustine up toward Mayport, near the Jax Beach Pier Sunday afternoon around 3:30 p.m., having traveled north on the open ocean. Planed the boat off, got up to 23, 24 miles an hour, and heard a horrendous crash, they were about 100 yards east and 50 yards north of the end of the visibly remaining pier. It was about an hour after low tide. The unmarked object they struck was a submerged flotsam remnant that calved from the pier during Matthew’s wrath. Realized the boat was taking on water … and made the decision at that point to continue north and get inside the ICW, versus running all the way south back to St. Augustine. Radioed the Coast Guard but after explaining that there were no injuries or immediate need of rescue, was told the Guard couldn’t help.
