CH-47 Chinook helicopter chasing a boat

In this video we can see a Chinook helicopter at a Low flying Area somewhere in The Netherlands.
The Boeing CH-47 Chinook is a tandem-rotor helicopter originally developed by American rotorcraft company Vertol and now manufactured by Boeing Defense, Space & Security. The Chinook is a heavy-lift helicopter that is among the heaviest lifting Western helicopters. Its name, Chinook, is from the Native American Chinook people of Oregon and Washington state.
