I used to live in Abbeville Road, Clapham, and used to go to the ponds on the common,and can tell you that the guys who fished there,were none too happy about power boats being sailed,"frightened fish and all that"i would have thought a hook in the fish,s mouth would be more frightening,mind you that was 30 odd years ago,perhaps the fishermen are a bit more mellow now,but i would,nt hold my breath,
