Displacement from Ship causing damage - CRAZY!

Since publication of this footage, shipping traffic has been slowed to proper speeds and monitored by the US & Canadian Coast Guard to ensure all vesels maintain compliance.

This video was part of a series of videos studied and analyzed by the USCG to determine that the upriver vessels were traveling anywhere from 3 knots to 5 knots over the allowed 8 knot (land relative) upriver limit (10.4 knot water-relative limit) during the shipping season.
