Fail: Sea Shepherd

[RantyDave]

Lets see, I put my time and experience working on boats up against your view of events.

You can borrow my degree in Naval Architecture as well.

[RantyDave]

what we see is an almost immediate separation of the two vessels following the impact.

No, the Ady Gil remained in contact long enough to go sideways through the next wave - the one that broke over the entire boat and drenched the cockpit. There was a lot of force involved in that collision and had the Ady Gil been a monohull it would have been rolled and quite probably physically run over by the Shonan Maru (see "Marchioness Disaster").

Another thing to note - as the collision occurs the people on the Ady Gil are propelled backwards

No. Before the collision occurs the crew, scattered liberally around the deck of the boat (what little deck there is) see it coming and fucking leg it back to the cockpit to give themselves at least an even chance of survival. That nobody was thrown into the water is a direct result of this and probably the only genuinely smart thing they did all day.

this is obvious evidence that the Ady Gil is actually accelerated forward during the collision.

If a collision accelerates a vessel forwards, it was clonked up the arse wasn't it? For god's sake, even your teenage boy physics must get that...

What do you think would happen if you just threw the bow thruster of the Arahura at the boat instead of bolting it to the hull?

That depends on how much it weighs, what it's made out of, how hard you throw it and the second moment of inertia of the Arahura.

Let's see, I will put my time and experience working with the laws of physics up against your view of the events.

Really? There isn't an engineering school on the planet that would even let you in with the claptrap you've been spewing over the last day or so and certainly not graduate. What "working with the laws of physics" are we referring to here?

Every tosser's talking about "our territorial waters".It was in Antarctic waters ffs

Yep, the waters in question are only covered by the Convention for the Conservation of Antarctic Marine Living Resources. They are not part of our, or Australias EEZ, although Australia has primary responsibility for search and rescure in the area.

EEZs are not accepted by many countries. They were unilaterally claimed by individual Nations, who under international law had only a 12 mile limit. Countries like NZ that could claim a 200 mile limit without a border conflict did so.

In 1977 the UN tried to clear the matter up with the "rules of the sea", which became law in about 1982.

But lots of countries dont accept the 200 mile limit or accept only part of it.

Japan and China for example, claim it when it suits, but fish "disputed" waters as they wish.

IMHO many countries accept 200 mile EEZs as long as it is cheap to do so. If you can just pay the claim holder, and fish these at modest cost, then that is the pragmatic solution. In fact, thats how they started, with the USAs calculation it was cheaper to pay Ecuador for the right to fish than it was to send the navy to enforce the US right to fish.

And thats how it will end. As fish stocks become more valuable, countries will try and increase the effective size of their EEZ. And at some point, it will be cheaper to dispute another countries claim than to pay the fees.

And such a shiny one as well. I shall use it with pride sir.

One word: Vectors. I'd have imagined you learned all about them in high school - that's teenage boy physics if anything. (And yes, vectors are purely mathematical, but we do utilise them extensively in physics...)

Look again and you will see that the boat is torn forwards underneath their feet. Upon reviewing that video you will also, I should hope, grant that the Ady Gil is not travelling at anything remotely close to 15-20 knots. I should also hope that you would be willing to admit that the Ady Gil is clearly accelerated both forwards and towards its starboard side at the impact.
I have to grant you that I was wrong, the two boats do not separate immediately - rather the Ady Gil is dragged along for as long as it takes its bow to break off.

At one point you consider the Ady Gil "very heavy" - and while I'd have to agree that bench-pressing 13 ton is quite a lot - it's the relative weights that are of interest. Would you also consider a 250 kg motorcycle "very heavy" compared to a 10 ton truck?

You use a lot of fancy words: "starboard bow" (that's where the klingons are btw ), "second moment of inertia". "centre of gravity" (should be center of mass, but we've been over that plenty of times), "hydrodynamic phenomena", "angular acceleration", etc. Fancy words intended to impress the audience and make yourself look knowledgeable while mystifying the whole deal. So thank you for your "ill educated yet curiously elitist" post. Good work on trying to turn this into a spooky-science debate!

As for the rest: nice troll. You obviously have an idea about what you are talking about (or you are very handy with a spooky-science dictionary) - but fail to use your reason and fail to recognise what facts you do have at hand what facts you do not. Oh, and thanks for the ad hominem bit - that was very entertaining. I hope you are having a better day than it could appear.

P.s. Please (re-)learn how to multi-quote. I understand that the button looks a bit different now that the forum has had an overhaul, but a man with your clearly impressive intellectual abilities should be able to figure it out.

I subscribe to the theory that it's a lot easier for a big boat to run over a little boat, causing it grave damage, than the other way around.

I subscribe to the reality that a small manouverable and capable of 40kts bot is a lot more nimble and able to avoid an impending collision that a large cumbersome vessel...and that in an impact, a large steel vessel is going to susteain far less damage the a small coposite vessel...

What would the courts say if a car driver ever used this stupid excuse in court as d defense for T boning a bike?

The AG was run over.

The AG was run over.

Only because they were acting like fuckwits

What would the courts say if the bike rider was deliberately swerving in front of the car, to force it to change direction?

The AG got what it deserved.

The only boat in the vid changing direction is the Jap whaler. And if a cage did that to a biker
what would 'you' say?'

As has been pointed out repeatedly, the AG powered on at the last moment, driving itself under the bow.

"second moment of inertia"

Until you learn what one is there's no point in discussing it. When you know what it is, you'll know why. Adios.

The Ady Gil was clearly not as manoeuverable as the Shonan Maru as it was dead in the water, without steerage, until very shortly before impact.
It appears evident to me the Shonan Maru powered up and turned to a Starboard collision course.
Having read the ebtire thread I must say been very impressed with the quality of some posts.
The paucity of reason in many is disturbing.
I was shockrd to see the illustration of a lawyer friends comment that eye witness accounts carry little weight at court.
How people could look at two videos and see such widely divergent events is quite shocking.
No wonder so many motorcyclists get hit by cars, if the inability to see, of so many posters to this thread, is indicative of the occular abilties of the motorcycling population at large.

If I was on the jury of the trial of the Japanese master I would vote to convict.

Had the Shonan Maru not turned to port at the last moment would there have been a collision or would the Ady Gil have got out of its way?
There seemed to be considerable overlap and the Shonan Maru did show impressive manoeuverability for such a large vessel. Had it stayed on Starboard tack would its turning circle have been small enough to cross the stern of the Ady Gil?
