RedactedNarrative: Operator stated he was traveling west when he ran aground near island 28 damaging the hull of V1. The operator also struck the windshield, breaking his nose. In the area where this occurred is a partially submerged island. The island is marked with a shallow water buoy, however it is a large area and at the time of this accident the buoy had floated quite a distance from the actual island. The position of the buoy and the island being completely submerged made it very easy for even a safe and observant operator to run aground.
