I remember that, which is why I mentioned it again here. These are phrases that people understand even when they are only casually informed and interested about the stability of ships.
Further, the notion of an "intact hull" (see Björkman's figure 1F) is another telltale. Björkman correctly begins with the intact-hull model of stability, although he just pulls all the relevant parameters out of some bilge scuttle and performs no calculations to arrive at his answers. But then he continues to use the intact-hull model after the accommodation of downflooding should have rendered it inapplicable.
Björkman's method is incorrect, but not solely in this way. Nevertheless it is egregiously wrong. In case there's any remaining doubt, his technical argument regarding
MS Estonia is just as stupidly wrong from a physics perspective as his claims about nuclear weapons and space engineering.
Then at the end he offers up his own private definition of "intact hull." Not only is it at odds with the definition from naval engineering (which gives rise to the model he pretends to use), it is factually incorrect even according to his own definition. But
@Vixen's ongoing misunderstanding of what constitutes an intact hull is—surprise, surprise—exactly the same characteristic, unique, wrong way that Björkman defines it. It's not a matter of being "open-minded" or an "original thinker." It's just wrong. And it's wrong in a way that points straight back only to Anders Björkman.
