After all the comments on the above, and casting back to my slightly flippant earlier one, may I just clarify that I too am in agreement with the new rules and happy to obey! I have, before now, encountered a small sailing dinghy, tacking from side to side across the whole of the harbour entrance, at right angles to, and at the narrowest point. As I was entering the harbour, this brown shadow came across in front of me as I was negotiating many other boats travelling both directions in the small boat channel. (OK, he was on my starboard side AND under sail, but even so!) Good job RIBs have good brakes!
As for the comments about turning the harbour into a VHF only zone. Well is that so bad in such a crowded place with so much commercial shipping? How many serious ribsters, (or boaters in general), do you know that don't have VHF? The possible alternative, banning ALL private small craft would be far worse!
Incidentally, just to prove us RIBsters do try to keep to the rules, below is a GPS track of one of my recent trips in and out. Only the return via the Eastern edge is now not official, (but it was when I did it!)
