On reflection.. I think you are probably quite correct.To tackle the OP's complaint,............
I suspect the RYA has decide to keep silent on various "difficult" issues for PR reasons. We are in an age where Politics has been driven by unproven science and hysterical reportage. The RYA are scared of appearing to not be be inclusive and green etc etc. It's far too easy for the liberal media to target supposedly whealthy yacht owners.
Which is why I consider they are not fit for purpose.
One only needs to look at how they failed to refute the imaginary evidence presented by a couple of self interested scuba divers to see how they are failing the people they purport to represent.
