Peter, I owe you a huge apology. Frequently I write thinking readers know things that appear self evident to me only to find out the reader hasn't clue. I assumed most people understood the concept of scaling. Big mistake as your post clearly establishes. When one scales a "boat" (and here you must understand that I am tslking about a boat not a part of a boat) one does not scale parts of it. You do, however scale its principle dimensions such as length, depth or beam or even all three or two. Clever readers will recognise that scaling the length will leave the sections unchanged, scaling the depth will leave the waterlines unchanged and scaling the beam will leave the buttucks unchanged. Scaling all three will change the size but not the form or its coefficients. A scaled boat will reveal itself as a copy through application of the various parameters I listed in a previous post. The concept of copies may appear subjective to you but as you may recall I provided objective methodology to establish the validity of a claim of copying. If you consider the various measuerments and co-efficients as subjective then I doubt if anything will clarify your vision. Perhaps this is why you and Matt can't reach some kind of amicable agreement. You just aren't speaking the same language from the same knowledge base.
