Tremendous amount of work you've put into this complex topic Mike.
The whole issue for AT is very much a chicken and egg situation as I see it.
Increased membership and funding is vital for AT to achieve its objectives as it stands and without achieving those objectives membership will struggle to increase.
Not only is the AT short of funding and staff but this is also the case with fisheries protection, the coastguard and the police.
This is why I believe that the AT should prioritise its effort to gain some obvious success in the sea angling arena that would add impetus to membership among sea anglers.
Coarse angling successes for AT are many - they are easier to achieve as freshwater venues are easier to police than the open sea.
There are a number of sea anglers I know who have withdrawn, or are seriously considering withdrawing their membership of the AT because of this apparent lack of positive results.
I'm probably not the only one who lacks confidence about gathering evidence about illegal practices at sea.
How about if each club member had a simple? aide memoire to help with evidence gathering - could it be simple?
