After 20 minutes on the top deck enjoying the wonderful views sailing out of Stockholm, we heard 'splash' and looked down to see that someone had gone into the water. We couldn't believe our eyes or that what we'd seen was real. There were lots of other people around but no-one else either seemed to notice or care. We ran down the stairs for 5 decks until we found crew and reported 'Man Overboard'. The ship was stopped and the rescue boat was launched.
