Jim, the concentrations of boats may differ with target species from area to area, but I think I'm right with the western approaches mob re bass. I suspect but stand to be corrected, the Eastbourne lot might be after migrating cod. The Hove lot plaice maybe??
I would say that most, I assume, will be following the current rules - some won't. Money makes the world go round and that's why they are fishing!! it's the politics, rules and enforcement that cocks it up in the big world. Under cover of darkness it's black fish taken on small sorties, right under our noses killing large numbers in small doses.
