The problem with this - and in fact the same is true of almost any action by a stand on sailing vessel, is that if you stop and he takes the action he should do to avoid you (perhaps he has only just realised you are under sail) then you actually make collision more likely (because his action will be to alter course towards you) and, as you have stopped, you are rather limited in your options!
When he's that close he's going to have to put his helm hard over to hit me.

Err, and just what action would you be expecting him to take in compliance with Colregs?

Let's say that he was doing 20 kts, you 5kts and on present course you would pass 100 yds in front of him, which he thinks is too close. If he alters course 10 degrees then he runs bang into you.

He's had me on his ARPA for the last 8 miles and hasn't felt the need to take avoiding action. At the last minute and without further reference to ARPA (which now shows him passing clear ahead) he suddenly changes his mind and puts the wheel hard over towards me. I don't see it.

I think that's exactly the situation rule 17 tries so badly to address.

The whole point is he hadn't seen you for those 8 miles and now he's mindlessly turning.

I agree it doesn't seem likely but if rule 17 doesn't protect you from that situation what does it protect you from? It's hardly there to protect you from vessels making an early and obvious change of course.

Excuse me for hammering home what I think is self-evident.

A "rule", however well designed, cannot, will not, never, ever, protect you. How can it?

I refer back to my "golden rule", stated earlier:
Never allow your safety to depend on the actions of others.
It resolves the conflict at a stroke. Take the action that you consider needs to be taken to assure your own safety, having due regard for 'rules' (whatever thay may be) but not permitting blind adherence to 'rules' to over-ride common sense. It's not hard.

It *is* self evident and I am 100pc in agreement with every word - with the slight quibble that sometimes due regard for a rule is absolutely no regard.

"Due" is the most glorious, majestically resonant and "Humpty Dumpty-esque" word (readers of Lewis Carroll will catch the allusion) in the English language. It is apt for all purposes. It has infinite meanings and a single meaning. If nothing is due, then nothing should be paid. Of course, each of us who chooses to exercise discretion in reliance upon it has to be prepared to defend and justify the meaning we place on it, in any given circumstances, against all comers. Perfect.

'Cos there was nought on telly last night I pulled up the latest MAIB digest for a dose of schadenfreude and found this conclusion from a close encounter between a trawling fishing boat and a ferry
He had come to accept that the
ferries normally passed close. Therefore,
being the stand-on vessel and expecting
the ferry to eventually alter course, he
delayed his action until it was almost too
late. The Colregs tell us that action to
avoid collision must be substantial and
made in good time. There is no doubt
that the action taken by the skipper was
substantial, but it could have been taken
sooner. Guard against complacency –
expect the unexpected.
 
Arriving late for the party is always awkward but........

My experience is that large ships make the minimum course alteration to port OR starboard to avoid hitting a sailing yacht .

Accordingly the best policy is to watch for course alterations VERY CAREFULLY and do not make early assumptions!!
Think about the speed differences; up to 30knts for the ship and probably 5knts for the yacht. That's just about the same as car versus pedestrian and you wouldn't make assumptions about what a car is going to do next.
My best investment has been a Sea-Me transponder and over the last 10,000 miles since I fitted it, I have not been required to take evasive action as ships have me clearly on the radar and can make the necessary course alterations to avoid collision.
With the speed differential I quoted earlier I reckon there is very little I could do to avoid an impending collision in the time available (that's not to say I wouldn't try!!).

Ummmm.....
As I understand it, in open water most bridge teams watch the 'S' band so Sea Me doesn't help ('X' band only..) - Great in congested waters, but then you are propably Give Way anyway, given all the Ristricted in ability to manuourve and constrained by draught caveats in the rule book.

This has always been my concern, even mid channel some of what you encounter is restricted/constrained and therefore has right of way over you as a yot. But how do you know? - By day I'd struggle to spot the cylinder at less than a mile, even with the bins.

So, my 2 penniworth - avoid the "risk of collision" first, and if you can't (too many vessels in a lane) then follow the rules, until sh its gonna happen, then alter course. Havent I heard this somewhere before but with no 6 miles, 3 miles and 120 metres to confuse me?)
:rolleyes:

FWIW, I'd say you're right, up to a point. On a smallish, oldish, two men and a dog ship you are almost certainly right.
On a brand new, well-found ship you are probably wrong, because the Officer(s) of the watch will have both radars on separate displays, and will be able to monitor both.
In the mainstream middle ground, both radars will probably be available, but the OOW will concentrate on one more than the other.
X-band generally gives the best picture, except in rough and/or rainy weather. In those conditions the S-band will give the clearest picture, so that is the one that the OOW is likely to favour.
Even then, the X-band Sea Me may help, to some extent, because it allows small craft to be detected by eye on the X-band radar at much longer ranges than would otherwise be possible. So they stand more chance of being seen by eye (and acquired by ARPA) before they get lost in the clutter or deleted by the anticlutter controls.
And there is a brand new dual-band SeaMe that does S-band as well as X-band -- but it costs a lot more.
