Yesterday there was a mystery appearance off of the Western shore. An enormous twin-hulled maritime lifting vessel of some sort (mobile dry dock?) was being towed by a relatively tiny tug. It had been seen two days previously about 20 km west, so progress is pretty slow! All through the daylight hours it revolved on itself virtually stationary and eventually passed round the Crocodile headland in the evening. What on Earth is it, and where is it going? How many months till it gets there?
