Their pricy boats fill up the harbour and you spend the walks along the front wondering whether or not they are thinking that you're jealous of their boat.
It's like very public caravanning. They sit on the back of their yachts and eat their breakfast, lunch and dinner within three yards of the pavement.
The difference between a yacht and a caravan. as far as I can make out is that a caravan is more spacious and you don't fall in the sea is you step over the edge of a caravan.
