Thank you Peter. Substantial and informative. "Banditry" is indeed what we wish to avoid so we put our BR20 down with a low handicap of 1050, to be on the inoffensive side.
I personally had originally estimated 1100, after racing against some class dinghies with a proven rating in that region.
Your information about the BRe rating is indeed helpful, but again I would like to know how BR20s are
rated, preferably the BR20s with the original Gunter rig. C.
