Yes, with the reconstructed GPS data of the yacht and the patrol boat on the plotter. Shame the broken down MOBO isn't there too!

V interesting viewing, thanks! A shame there is so much background noise...

Fascinating reconstruction of their courses. Looks like Atlanta was keeping out of the MPZ, and the tanker was pretty steady on heading 256 to 258, until the patrol boat turned to Atlanta and said something. At which point Atlanta changed course sharply to starboard just as the tanker finally started her turn to starboard as well.
What did the patrol boat actually say to Atlanta???

You can appeal against conviction (if you plead not guilty) or sentence (regardless of plea) or both. If he appealed against conviction, if he had adequate grounds, and won his appeal, the fine would be overturned.

I think the skipper here was fully conversant with the LNTM but that didn't prevent the collision...

Fascinating replay - I have a lot less sympathy for the skipper now.
I had assumed he had made a more substantial turn to starboard than that

Given the wind direction and the size of kite on that boat, I'd be willing to bet that was the highest he could sail.

Do you know which mark he was making for?

The one just to the north west of South Bramble I think.

I can't work out what the wind direction was.
If I interpret the data correctly it seems like pretty much due west, in which case he should have been able to sail pretty much due south.
I am guessing that the judge believed that he did not keep his eye on the tanker after making his first change of course - in which case guilty as charged

Was on the water that day, wind was SW. I suspect the first change of course was a gybe.

Me too. Of course the plot will be relative to the ground so a couple of knots of easterly tide will be on the Atalanta which will take a fair bit of south out of his course IYSWIM.
PS: On another topic, am I the only one thinking:

I suspect this has done a lot of damage to Cowes, Cowes Week in particular.
I gave up on Cowes Week as a result too many annoying money grabbing spectator boats spoiling races that were costing too much to enter.
Knowing that the course you are set involves risking bankruptcy for one cock up makes me prefer getting the boat delivered somewhere where the paying entrant gets a reasonable deal.

Nice video. Why does the plot show the Atalanta going down the stbd side of the tanker?

According to what you and I posted back in 2011 the next mark was S. Bramble ( then down to W. Ryde before heading for the finish line)
I looked up what Bramblemet was recording. Around 240-250° ( ie wsw), 12 - 14 knots

I would suspect the reconstruction is based on data from the tankers Voyage Data Recorder. the Voice and position information for the tanker taken from the VDR the Electronic Chart and GPS. heading from Gyro.
The posistional information could have come from GPS data for the sailboat and patrole boat. And recorded radar data from the VDR. once the colision had occured the sail boat would have been to close for radar to show or distinguish so the data would have to rely on yachts GPS alone.
Quite simply the limits of acuracy of GPS from two sources are not sufficient to determin which side.

It does, however, put the mockers on the claim so confidently made many pages ago that the Atalanta was set to pass clear down the Hanne Knutsen's port side, and that only a turn to starboard by the Hanne Knutsen caused the collision. Not that it made any sense before the tracks were published either, mind you.

I have downloaded the video as a .flv
Does anyone know with what soft I can view it ?? Or convert it, or where I can get it in some other format ????

I don't think it has any significance to the verdict but assuming the video/audio/chart are properly in sync the collision occurs 20 seconds after Starboard 20 was requested and 15 seconds after "Hard Starboard" was requested. So the collision really was right as the ship physically began to turn.
1/2 a ship length later and HK's stern would have been moving sharply away from Atalanta...
