As we approached Oban on the ferry from Barra, I mistook this ship for the Crystal Serenity, which is slated to sail through the Northwest Passage later this year. But no. It's the MV Artania, which was anchored offshore because it is too big to enter the port. This particular Motorized Vessel is 231 metres long and weights 44,348 tons. The Crystal Serenity is larger still, at 250 metres and 68,000 tons. Oban is a port city of 8,575 people, and is designed to handle great numbers of visitors. The Serenity, which carries more than 1,000 passengers, is slated to put in at Cambridge Bay in Nunavut, population 1,766. You do the math. I whole-heartedly support adventure tourism in the Arctic. It brings money to Nunavut, and also increases awareness of northern issues. But these numbers? The smart move might be to control ship size by limiting the number of passengers per voyage to maybe 250. Just a thought.
