The yellow tug working around the Harbour is the Capricorn Alpha tug. The tug is a ‘sweep tug’ and is working on the Channel Deepening Project.

The tug tows a large blade along the sea floor to even out the troughs and humps left by the Fairway. She also helps scrape off the shallower parts that the dredge can’t reach. It might look like she’s working in circles, but she’s definitely hard at work!
