The nice folks of the Classic Motor Boat Association suggested I should link to the Motorboat Museum near Basildon:
http://www.motorboatmuseum.org.uk
There are some stunning exhibits (see El Zonco below), but as a father of kids of ten and twelve, I must say that judging by the website one of the nicest things about the museum is that its staff seem to have given a lot of thought to entertaining children who visit.
