Introduction, as critic the official opinion.
----------------------------
As explained in this site, it is not possible to
agree with official version as though the INS
"Dakar" sunk as result of a collision with any
great ship, because there is negations of proofs.

Also we refuse the version as if the Israeli
submarine were attacked and sunk by enemy.

Do not were visible any proof witness that INS
"Dakar" were attacked by torpedo or were bombed.

We are refuse the must of other official opinions.
We are explaining and proved why the official
opinion was not correct. Up this time. 2001.

There is direct proves that the submarine did not
sunk immediately as it would be in collision case

We apology because of the must of the proofs that
were obtained after "Dakar's" found no were showed
because the officials watched the all as secret.

These hindrance do not got us to be more accuracy.

For the inquest the falling of INS "Dakar"
were used only the published data, as the photo
reproductions, design data and several details
that were obtained after "Dakar" found and the
circumstances were updated  with veterans.
We based our assuming on the real proofs.

The personal summarize version of the disaster.
The rather hypothesis of reasons of "Dakar's" loose. ---------------------------- There is two realty main versions of falling the "Dakar": 1. The INS "DAKAR" has wreck and sunk because in the hull of submarine occurred a crack. 2. Though 1968 th version the "Dakar" was caught in the special net, then after dismantling of the command bridge and the added tank it were sunk. 3. The all other versions about falling the "Dakar" that described in this site, are left as real versions made with accordance to evidences that we got. But the explained down version is rather of them. 4. In all cases we have not the definitely answer for fate of the 69 men's crew of "Dakar". The rather hypothesis based on opinion as with "Dakar" occurred a wreck as crack in the hull of the submarine. This version explained just down.
As explained in this site, there were several passible reasons of causing the wreck, but for a rather version we selected the evidences as the hull of "Dakar" was destroyed yet in the time as the submarine were on the building berths. Upon reminds of eyewitness we know that the hull of "Dakar" first were destroyed yet in Portsmouth, at the time as it were raised on the building berths for a capital repair and modernization. The hull got a crack, and the ship were filled with water. Yet, for repairing after occurred were need several months of works, as welding of the cracks in the hull and for other inner repairing. We should to suppose as these cracks occurred because the mounting of submarine on the building berths for executing the repairing works, were doing in not perfectly way, that caused a great inner tensions in the hull, that finished with cracks, yet at the time as the submarine stained on the slips, in Portsmouth. These cracks were welded, but after the repairing works ended and the submarine were released in the waters, the inner tenses returned. If this version is correct, then the area of this welds should turn be an area of exstremal inner tenses in the hull. Then the cracks should be occurred just in area of the last welding. The picture of this destroy have be seen on the photo and from the repairing technology maps. The telling give suppose that the hull of "Dakar" were weaker with comparison to other submarines. As the circumstances was not extremely, the hull has stand the loading, but on extreme high wolves the hull got a crack in the area of concentration of extremely inner tenses, and so caused the wreck. The character of the crack, as it seen on the video picture, is very simple as a crack that occurred because of the -metal fatigue. We know that the Mediterranean in the area of sunk were storming. The veteran, that run with INS "Dulfin" in two days interval after, tell as a sea wolves were so high and stark so as after one of them the water filled several sections of submarine. All these evidences defined our last choose of the rather version of the reason of the wreck. Although, there is other real versions of the wreck, as it explained in this site. All versions of occurred, that described here before of this, also could be seen as correct thesises of the wreck as based on real data. We choosed the last version as rather because this version based on a supplementary witness about the former wreck that caused with "Dakar".
* What could happen after the wreck. * --------------------------------------------- The disposition of the ruins of submarine are witness that from the moment of the wreck occurring up the sinking, passed a long time. As reminded, there are proofs that witness as the men are fought for rescue the ship and the one others, they released the emergency dam-buoy, But instead of got the help on the SOS signal, could been that to the wrecked submarine were come an enemies ship, and the stranger men demounted the command bridge, took the tank as an interesting thing and torn away the dam-buoy system. As reported in past, the submarine and it's crew do not were armed. After the last (September's 2000) searching for the ruins of "Dakar" by the Nauticous company were published as were raising the "Dakar's" command bridge, but there is not found even one personal thing of the 69 men crew !! This report also using evidences that support our opinion as the "Dakar" was caught by enemy. So also could occurring in the other version, in a case when the submarine were caught in the net, as it explained in this site, as a first version. In the meantime we found not better explanation for the proofs, evidences, that we got. Maybe yet left the eyewitness that once would to tell the absolutely truth, what occurred and what caused the "Dakar's" sunk and the lose of 69 men's crew in the Mediterranean, 25 January 1968. Only then we will know the truth about "Dakar".

The edge of the "Dakar's hull destruction.

The vertical edge is the line of torn the submarine hull, it remember the metal fatigue destroying of a steel sheet.
Several remarks about the seeking after "Dakar"
In adding to described in this site I wish say as It was perplexity the behavior of our headquarter. Why after the "Dakar" do not have communication in the ordering time, does not sent an aeroplane for checking the area were "Dakar" have to run. I can not believe as the aeroplane don't were sent. It is perplexity as the seeking for the vanisher submarine began in 30 hours later ? Is perplexity the all history of seeking for "Dakar", because all actions and all "theoretical findings" of them, were visible as fantasizes, that absent logic. Always the "Dakar" were seeking in area, where the submarine could not be coming. It is perplexity as up this time all details bending with the disaster with "Dakar" are holding as actual secret, as in real the secret is not from an enemy, but the secret hold for us.
Now we have wait for the official report and the final opinion after the last searching that were doing by the Nauticous Company. It is the end of the last resume.
