Is this the sailing equivalent of not slowing down when someone pulls out in front of you doing a slower speed? Or tail-gating when someone cuts you up / undertakes you?

You're the idiot if you think you can get away with it. You know damn well how the camera distorts photos like that. Look at the relative sizes of the boats and frigate.
You're just a gob****e who rolls out the same rubbish again and again. You've tried it with those same photos before.

You are demonstrating exactly what I am saying here.
Even if the boat didnt actually touch ( I posted a photo of Velas stainless bow rail with grey paint damage at the time) you think it is safe.
Can you see the shadow from the sail on the frigate ?

They just weren't that close. There are well accepted techniques for measuring distance on photographs. Try that.
Now if you'd a photo (even a photshopped one) of the nearest boat twisted around with its pulpit ripped off, the forestay fitting destroyed and the mast coming down and a scratch in the grey paint of the frigate then you might get a few bites.

As an educational process and to get something constructive here, can you please explain the well accepted techniques for measuring distances on photographs?
To my ignorant and uneducated view, the picture does appear to show the yacht very close to the ship. i appreciate that lenses can distort distances but would love to hear what the technical view of the photo is in terms of distances?

And me, the second one looks to be within the wake of the frigate to me and, from the shadow, not far off being in contact.

I was there, it was closer than close !
I dont know why the raggies keep jumping to the defence of these idiots who sail into ships, the mind boggles.
As to it is irrelevant because its not within 400m from egypt point , possibly correct , I havent any way to check but it was just off cowes.

Well personally I think anyone daft enough to sail into a large steel structure, moving or stationary, deserves all they get. Regardless of stand on vs give way status, it's plain daft.

Just basic trigonometry:
The first is to measue the size of known object on the frigate and yacht. The bigger the better to minimise the effect of errors in the measurements, so height of mast on the yacht and height of funnel or mast on the frigate would be good candidates. That way you can get relative distances of the two objects. By knowing the absolute distance from one to the photographer, you can work out the distance to each and distance between them.
Second technique requires knowledge of the camera. If you know the focal length and sensor size you can work out the field of view of the camera at a certain range (assuming the photo hasn't been cropped). Again take a known length on the object and use it to determine the field of view and you can work out the distance to it. Use the formula:
field of view/distance to object = focal length/sensor size.
Of course all measurements will have a certain degree of error so you'll have to calculate that uncertainty to qualify your result.

Based on the above I have done the calculations & have come up with 6 inches & also you need a sensor clean DAKA which proves that the pictures have not been cropped

I think that's probably true. Remember that anyone who's top speed is about 5 knots has necessarily got fewer options than anyone with a top speed in the 20s. And when crossing the channels in the Solent, what to you is a quick look both ways then a minute or two across, can be a 10 minute or more sail to cross. If you decide to cross ahead of a ship there comes a point where you are committed, and if you misjudged it you're going to incur the wrath of the patrol boat at the least. Whereas if you misjudge it in a MOBO you just spin the wheel and open the throttles. Can't do that in a slow moving yacht.
Don't see very many dangerously close encounters though.
p.s. bringing up those photos again does just smack of someone trying over hard to prove a point Pete. You're probably right that at least one of those boats LOOKS to be closer than I would be comfortable with, for sure. But it's not anything that hasn't been done to death here before.
I just went and had a look for the original thread, to do so I did a search on "threads started by DAKA".
Quite revealing that mate, anyone would think you had something of an anti raggie agenda! Whatever good points you may make are somewhat lost in the noise.

Is this available online somewhere? I've had a look but I can't find owt on youtube.

I'll put my hands up to that, from my point of view the original post goes back to 2008, but remained unresolved as scuttlebutts would never accept Vela did anything wrong . The incident was almost identical to the Atalanta case , obviously I'm going to repost it as I told you so !

Apart from different point of sail, different sail plan, different location, different angles of crossing, different relative positions, not in the area of concern, no moving prohibited zone, no broken down motorboat, not in a narrow channel, no pilot, no escort launch... though there is a sailing boat I see

You missed the principal difference. This ship is painted in low visibility grey, not bright Orange! I think anyone could be excused crashing into a ship that goes out of its way to avoid being detected...

Oh, I didn't see the ship...
