One of the things I enjoy about being a barrister is that I often get a case that involves learning about some area of business I'd not otherwise have anything to do with. This case - The Port of London Authority v Tower Bridge Yacht & Boat Co - is on a much bigger scale than the sort of thing I deal with, but it's clearly one of those cases that involved a lot of delving into detail. If you're at all interested in the history of Thames moorings and river trade, paragraphs 44 to 116 may well be to your fancy.
