Catamaran hit by 600' tanker

[FarCry]

I found this posted on another site and thought it was interesting. To view the video click here Latitude 38 - The West's Premier Sailing & Marine Magazine and scroll down to the 4th picture entitled video of the day and read the short text. You will see an uninsured 42' catamaran hit and dismasted on purpose. Can you guess why?

After you have your hypothesis go here to see the rest Latitude 38 - The West's Premier Sailing & Marine Magazine . Scroll down to where it says the answer to Wednesday's quiz and read the text before watching the video.

What do you think about the problem and the solution?

i don't get why he hit them. after hitting them, they were still on the cat.

Did you read the text explanation under the second video?

[mrwuffles]

All it said was they t-boned him so he could get off.....how does t-boning make it easier than any other way???? i did read the second link story.

link states video removed

Now I understand why some captians will go down with there ship.

i read the whole article but i still don't get how t-boning the boat helped them get off. after getting de-masted, they were still on the ship so i don't see what hitting they achieved.

Uh, the captain and crew did get off the catamaran. There is a picture of him 'after' the rescue in the second link. There is a lot that was not shown in the first video like where the hull of the cat went after being hit (presumably down the port side of the container ship). You saw the cat and it's mast getting felled like a tree in a forest.
The cat could not steer because it's rudder(s) were bent over 90 degrees by the whale surfacing. The sail drive engine had been shoved through the hull by the impact of the whale (while gouging his flesh) which caused some compartments to flood also rendering the cat helpless. The captain of the container ship steered into the cat so his crew could expedite the rescue of the crew through some opening in the ship that was not visible in the video.
The reason for this disaster was first and foremost the whale rising to the surface beneath the cat (shearing its rudder and rendering its engines useless). I have often wondered about this kind of thing occurring on the ocean where a whale might cause inadvertent damage to a boat by rising in an inopportune spot, under a boat.
Without getting into the argument of whether a spade rudder vs. skeg rudder would have helped it would seem that the sail drive mechanism is a big liability. A straight shaft driven propeller may have bent and even broken the hull as well during an impact like this.
A solution to this problem could be to have pre-recorded sounds of killer whales transmit from the hull of the boat into the water. This might induce the whales to consider surfacing a bit farther off. The electrical cost of such a device could be pretty expensive although it could be rigged to a depth meter/fish finder to trigger when on the open ocean. No one wants a whale or a submarine to surface beneath them while out there in a small boat.

Not to nit-pick too much, but the ship looks like a bulk carrier, not a tanker nor containership.

Probably didn't matter to the cat, though.

There's a theory that might explain it, but it's just a theory. Look at the second video. In it, the ship was fairly close to the catamaran, but, as time passed, the cat drifted further away from the ship, apparently out of reach of a throwing line. If the wind was strong, and at the correct angle (coming from the right side of the video picture), perhaps the wind was turned by the side of the ship, and, when the cat was near the bow of the ship, it was backwinded by the wind coming off the ship, and the wind pushed the cat away from it, as appears to be what happened in the second video. In the second video, the cat begins to move away ftom the ship so quickly that it almost looks like it's being driven under power, and, since we know the cat's drive was damaged, only the wind could have caused it. After failing twice to get close enough to recover the cat's crew, the ship's captain might have concluded that the only way to get close enough was to actually nudge the cat, at a low enough speed not to crush it, and to have crew at the bow of the big ship, throwing a line to the cat's crew. If that was the ship captain's plan, it appears he controlled his big ship's speed and direction very artfully.
