Editors note: Great video with a brilliant technique: Move your phone while watching and see the different angles of the full 360 degree view. Amazing!

When a vessel navigates in confined waters, such as in a harbour or narrow channel, it is well known among experienced pilots that the ship handling is greatly affected by the hydrodynamic forces and moments acting between ship and bank or sidewall of the channel.
The U.S. National Transportation Safety Board (NTSB) has released a Marine Accident Brief about an accident that occurred in March 2019, involving the towing vessel Dixie Vandal, noting that the BNWAS alarm didn't prevent the fatigued pilot from falling asleep.
