But the "m" in this case is just 20 (ie the 20m length of the hull deformation*); and then also, the ship can't have been travelling at more than, say, 10 knots/hour2, and if the damage had been caused by the ship shifting on the sea bed, this wouldn't have taken more than around 15 seconds maximum - so the "v" here would be 10 divided by 15 = 0.5. So "v2" would be 2.5.
And therefore 1/2mv2 would be 0.5 x 20 x 2.5. Which makes 200 jills. And Archimedes' Principle dictates that this is obviously far too few jills to buckle and twist the hull. Something else must have caused all that deformation while the ship was at the surface.
* I'm even being generous by opting for the 20m length of the deformation, rather than the 4m height
How long before we are asked to consider the African Swallow's carrying capacity?
This whole story is so simple:
The Estonia sank when her hood was knocked off by waves of a storm. Lots of people died.
There was likely stolen/black market Russian military/space/missile hardware in one of the vehicles in the car deck which seems to have been important enough for someone to remove covertly in the 4 days between the sinking and the first dives to the wreck. Evidence of which is the railing of the bow ramp cut off and stacked "neatly" on the bottom.
Sweden got weird about surveying the wreck and recovering bodies.
The problem, at least to me, is that the second two have nothing to do with the sinking. It is standard CTist methodology to combine the three elements as proof of evil-doing. The idea that Estonia was sunk to protect Russian secrets is embarrassing as it shows a complete lack of basic naval practices, and I won't get started on the covert stuff.
If the Russians wanted to stop Estonia they would have used surface ships to force her to sail to a Russian port where she would be searched and arrests could be made. To my limited knowledge this is something just about every navy would do. Agents onboard are not going to sabotage the ship because getting off a large vessel, even in calm seas, can be tricky, especially with sensitive equipment. Exiting in a storm would be suicide, especially for a scheme involving a Russian sub, mini or otherwise.
This circles the conversation back to the beginning wherein the Estonia sank because her hood failed and fell off, flooding the car deck. In 70+ pages there has been nothing posted to even remotely draw this fact into question.
