I live in Beijing about 50% of my time, month there then a month UK etc.
I dont know of any boat clubs whatsoever, I do travel around china quite a bit including well away from "western" areas but water hobbies seem to be boating as in riding in them, fishing and kite flying (they like the steady air streams you tend to get along the rivers) but then Im all new to this, I know a couple of steam enthusiasts and one is into boats but lives in the south and is active on a number of forums.
