Already aware of this. And I agree, the regular "problem boaters" are a far bigger annoyance, and the biggest threat imo to boating (as they may cause an overreaction from society in general).
Example, there is an ongoing dispute near Saltford. Homeowners complaining about boaters, in one case a homeowner unmoored a boat that they didn't want in front of their house (they were given ASBOs). Here, I think some homeowners are being a**seholes. HOWEVER, when we moored there it was obvious that some boaters (shed-boats, specifically) were overstaying and being a general nuisance with engine running etc. Would the homeowners be a**seholes to all boaters, were it not for the few generally difficult boaters? Not sure, but the difficult minority seem to be harming the rule-obeying majority (if it is a majority, not sure anymore).
In Brentford now, we'll see if it's a similar trend round here as we head up the GU.
