How long did you say that boat was again -didn't you say 8m?


I didn't say, you did.

No, I just gave the name of the boat, it was you who lied about the
length. Why not look her up in Google -you'll be astonished and embarrassed!

First of all, do you even know what you are talking about? I was talking about
the Capsize Screening Ratio, devised by a number of naval architects to give a
rough comparison of inverted stability or LPOS with only the boats basic
dimensions.

You mean the formula I just posted? Having given you it's theoretical
basis you must now surely accept that it is no more than a rough
nmeasure of the true initial stability. No matter what you say or think
the maths is simple and shows that I was correct.

Second, the LPS and inverted stability are two completely different
things. Such profound misconceptions on your part!

Doug, inverted stability is _not_ predicted by just the beam and
diplacement. If you accept that, then what does the capsize screen
really indicate?
(Hint: How about a rough indicator of stiffness?)

Have you heard of the metacentric radius and do you know how it might
related to beam and displacement?
