Blue Tug Boat on "Guard Duty"

The barges and stone scowls are sharing the narrow channel at the mouth of the Merrimack River with commericial and pleasure boats. Many boaters are being respectful of the construction crew. Unfortunately,some boaters have been discourteous - driving by too fast and creating wake (in violation of navigational rules for the mouth) and / or getting too close to the barges. This creates a safety risk for the crew. One of the tug boats is being use to patrol the mouth while the barges and scowls are moved. The tug boat positions itself so it keep boaters from getting to close or force them to slow down. In the video you can see (off and on) the blue tug on the right side of the screen on "guard duty."  These tugboats are fast, powerful and very agile... not a boat you want to mess with.

Not the most exciting video but documents another aspect of the jetty repair operations.
