Non dimesionalizing ship's moment of inertia

As Heimfried correctly noted in the previous page (it is always useful to read the thread first) - the above non-dimensionalization formula would be valid only if the talk is about the Area moment of inertia, or Second moment of area, which is a geometrical propriety of an area: https://en.wikipedia.org/wiki/Second_moment_of_area

It is very different from the Moment of inertia, which is a mass property of a body and is of interest in the study of the body dynamics: https://en.wikipedia.org/wiki/Moment_of_inertia

 

No, it was a pure, genuine and sincere conversion error.
One more reason to stick to units one is most familiar with (mine are SI).
I have corrected the error, thanks for noting it.

 

Mass moment of inertia or transverse waterplane moment of inertia?

The latter can be compared to that of a rectangle of L by B and is typically the waterplane coeffiecient squared.
