RYA legal and cruising have replied very quickly.
They are aware of it and with help from the User Group representative who sits on Council (I guess Mike Shefras) are following up on our behalf. They also enclosed a follow up newsflash from EA (their website) which tries to allay fears. Not sure if it does for me but then I am a sceptic when it comes to EA. Seen them in inaction before.
I have requested that RYA try to give it some coverage in their Email newsletter, to show they do do things for us on the Thames.
