In 2010 there were a fleet of six or so Maersk container ships moored together to ride out the recession in the sea cargo business. I ended up on a job on them for 10 weeks, sailing out from Gourock on The Ali-Cat (now the Dunoon ferry) every Monday morning for a week's work, returning on the Friday. We would stay in the ship cabins through the week. Working below decks we'd hear the odd thing clanking off the hull, we were 20m below the water apparently. Those ships were massive, some ended up being re-engineered into smaller types and one sailed to India for beach scrapping. Pretty amazing loch as I recall .
