Damo, welcome amongst us. As far as I can see Charters is an old Dutch barge converted into a bar/restaurant, moored in Peterborough's city centre. Two things, some of my most prolific fishing has been in areas least likely to be fished, like city /town centres.
Second thing, imagine how much food waste is going to be "dumped" into the river in the vicinity of this barge.
Get yourself there and fish for whatever takes your bait. You may be surprised how few restriction for angling apply in urban areas.
