Suggestions for boat purchase

Combined is 23-and-a-half stone.

We're in South-West London. Little unsure about clubs. River sailing seems like it might be a little limited (I did a little when I was a kid and remember that you never got much of a run when sailing on a river). Would prefer a decent large reservoir but they all seem to be a bit of a trek (when considering London traffic).

In order to avoid the standard answer (that you should sail what I sail, since it is obviously best):

What club do you have in mind, or failing that, what area?

What is your combined weight?

Hi, new to the forum and hoping I might be able to get some advice!

Spent much of my youth sailing (mainly single-handers - the last being a Phantom that I had from aged 17 to 19). After 10 years away from sailing, I've fallen back in love with the sport while on honeymoon in Zanzibar (very tricky winds!)

What's more, my wife has also discovered a passion for sailing. She'd never sailed before, but loved it (mainly sailing Hobie 14s, but we also went out on a 40ft racing cat with a crew).

Anyway, we're both now keen to join a club and buy a boat. Budget is around £2000 - £3000. We're looking for something reasonably speedy but not too skittish (an RS800 would probably not be a good idea!). Does anyone have any thoughts as to a good class for us?

Cheers
