Port to port?

[JumbleDuck]

You are mistaken.
1) The regs are much wider in scope than that.
2) The rules (amongst other things) assign obligations to either stand on or give way as soon as a risk of collision exists.
3) The action to avoid a collision (e.g by the give way boat) must be taken 'in ample time' .

But completely fails to define these terms usefully.

In the Aegean, where ships are travelling busy routes without traffic separation schemes we often hear them on VHF discussing passing intentions. Reference to AIS shows them to be 10 or more miles apart.

They do it around Gibraltar too. Often heard them chatting about their intentions. I suspect in the case of the OP the other boat didnt have a clue and the OP response was totally correct with his head finger twirling which most sensible people understand!

From my previous post, it looks like the vessel going downstream has priority but the vessel going upstream makes the decision as to which side they give way on.
Going downstream has priority seems logical but the give way vessel making the choice as to which side they give way on doesn't.

Those rules are very confusing because they appear to be ambiguous in their meaning. They use both "vessel going downstream" and "downstream vessel" - are those supposed to be the same vessel? because that is not the strict meaning

Rereading the extract (from a PBO poster) that I put in #7

NORMAL VESSELS GOING DOWNSTREAM HAVE PRIORITY OVER
THOSE COMING UPSTREAM, BUT UPSTREAM VESSELS CHOOSE
WHICH SIDE THEY WILL GIVE WAY ON

it is the BUT that confuses the issue, if it had said AND then it would be quite clear that the upstream vessel (proceeding downstream) has complete control. Which makes sense to me.

I suspect that when they say "upstream vessel" they mean the vessel proceeding upstream (or what we would normally call the downstream vessel )

The bit about the downstream vessel being at the mercy of the current strong suggests that is the vessel proceeding downstream

I think things may have improved since the days I did my CEVNI thing when I seem to remember it was only upstream or downstream with no 'going upstream' etc. The context makes it fairly clear but it is a typical bit of bureaucratic writing.

Actually, the Cevni regulations themselves seem very clear to me.

It's the guides (or at least the one I've got, and some online resources I've seen) which produce confusion by using the colloquial 'upstream vessel', which could be read as upstream going (correct) or upstream of the other vessel (wrong).

In the Cevni regs. every single reference to vessels in relation to upstream and downstream specifically says, e.g. 'vessel proceeding downstream' or 'vessel turning upstream'. (What upstream and downstream means in terms of the rivers and canals themselves is set out in the definitions at the front of the document. )

I've recently been learning Cevni rules in anticipation of taking the exam, and have found the RYA publication 'European Waterways Regulations (the CEVNI Rules explained)' very poor on this and other counts.

It was because I was getting confused by that booklet I dug out the Cevni rules themselves. They're long (c 500 pages) but all pretty clearly set out, and can be downloaded (pdf) free from here: https://www.unece.org/fileadmin/DAM/trans/doc/2010/sc3wp3/ECE-TRANS-SC3-115r4e.pdf
