Left out of the demo was Atlantic Larch which also had real work in the harbour. The tug returned to Halifax last week after a quick refit and hull painting in Shelburne.
Atlantic Larch has no firefighting gear, but does have a towing winch. Here she is returning from Fairview Cove where she berthed Atlantic Cartier.
