Somewhere (TM) I have a book of the Rules of the Royal Yachting Association (governing body for the UK) that came with two little models with a rotatable "boom" so that the rules could be acted out on the tabletop. But that was thinner than the RAC Rulebook covering most forms of motorsport and that was a lot thinner yet than the FIA International Rulebook. But the last two had a much wider sweep covering organisation, courses, public duties (eg police) technical regulations, etc.
While racing yachts I used this to time starts, and obviously when navigating rally cars etc.
