Straw man.
You insisted you were competent in physics when your dubious physics-based arguments were challenged. That's why you assured us that you studied physics for five years. No one is saying you claimed to be a physicist. However, the level of education you've claimed on the subject, if taken at the college level, would be consistent only with physics majors. It took much effort to get you to reveal the actual details. Obviously you wanted to convey the impression--however inaccurate--that you could formulate and understand arguments based on principles of physics, because you had made a suitable academic study of the field.
You have deployed arguments that would ordinarily require specialized physics knowledge to understand--and therefore to present correctly and defend. You presented a YouTube video on metacentric height as it applied to a schooner-type hull. You insinuated that it was a subject you understood and your critics did not, and insisted that the video proved your errant belief regarding transverse ship stability.
But when you tried to restate the principles in the video, you could not do it. You failed on basic concepts such as the difference between a point and a line. When asked how changing the hull shape would affect the computation, you ignored the question. When asked how the model would have to change in order to accommodate flooding, you ignored the question. I say you're ignoring the questions to avoid having to reveal your ignorance. I think you want people to believe you have more knowledge and expertise than you actually have.
You are not at all competent in physics.
This would be roughly equivalent to two semesters of American college freshman physics--or advanced high-school physics--such as would satisfy the physical science course requirement for all graudates at the university where I taught. Your illustration appears to be the syllabus for physics O-Level exams, roughly equivalent to college admissions exams. That is a basic level of instruction in physics, probably not even incorporating calculus.
Regardless, you have not demonstrated any competence whatsoever in physics at this forum.
