Our team was hired to reconstruct the collision incident. Of particular interest was the determination of the location of the collision on the waterway, what boating rules applied, and whether the boats had an opportunity to avoid the collision. To perform these tasks, we first inspected and 3D laser scanned both damaged boats, and performed a static alignment of the two boats at impact. We then performed on-water testing of undamaged exemplar boats to characterize their dynamics while performing a variety of maneuvers, including collision avoidance maneuvers. A site inspection was then performed when the water level was at the same height as the day of the accident to properly assess site lines. Finally, we extracted the metadata from digital photographs taken of the water-skier behind Boat 2 to assist in confirming the boat’s path and speed.
