Hi there,
If you are looking in Europe, your best bet is the Spitfire.
Not only an extremely well built machine, but sales outstrip other 16 footers by far, allowing a one design race circuit before the F16 circuit really takes off.
In fact, the F16HP circuit in the UK is very light if not non-existent at the moment, but the Spitfire sees 20 or so boats at a big event already.

Failing that you could join me, one of only two in Scotland!
