Tony, yes quite so, the Herreshof is a mini-keelboat. Although there is now, I believe, a centreboard derivative by an 'approved' sort of boat designer in the US, using some kind of more 'modern' boatbuilding techniques. In fact, wasn't someone about to start building one talking to us somewhere on the Forum? - had a look for it, couldn't find it (for goodness' sake my proclivity for not-being-able-to find-things now extends to the Forum). Thanks for the picture, which doesn't actually do justice to the sweet lines, especially the sheer.
The Bala Rally promises to be quite an event - not only sailing and beer talk, but abstruse philosophical concepts to be bandied about. What, Graham, is a Manichean when he's at home? Please, however, do not assume that I have any tendency towards floccipaucinihilipilification just because I don't know what you're talking about.
