Most cruise ships using Halifax do not request tug assistance. They are all bristling with thrusters, and certainly do not want tugs with their black old tire fenders scuffing up their nice white hulls.
However once in a while they do take a tug. Such was the case today with AIDAaura, which was tied up inside pier 23, in a narrow camber, and it was windy.
I don't believe that Atlantic Willow needed to touch the ship however. I think she just put her line up to the ship's stern and pulled her out and helped to turn her to seaward. The tug was built for duty in Point Tupper, and is the only Atlantic Towing tug registered in Port Hawksbury.
Atlantic Willow is a 4,000 bhp stern drive tug built in 1998. She is fitted with fire-fighting gear, but has no towing winch.
