Resistance techniques

Hi!

I have come across Radojcic's regression equation mathematical model which was developed for the NPL high speed round bilge displacement hull series, however as is the norm, the equations were developed for 100000 lb or 45.36 tonne.

So my question is, can his mathematical model be used for other displacements as it is in my case?

I'm attaching a link to his paper

https://www.google.com.mt/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CCsQFjAA&url=http%3A%2F%2Fwww.boatdesign.net%2Fforums%2Fattachments%2Fhydrodynamics-aerodynamics%2F75587d1351353775-two-hulls-has-least-drag-resistance-trim-predictions-npl-high-speed-round-bilge-displacement-hull-series.pdf&ei=7zAnUYvtKs-K4gSmrIDwDQ&usg=AFQjCNFvCEyyPMNHB_YKeDV9vfMBA3gpuQ&bvm=bv.42768644,d.bGE

Note that in other instances such as Mercier and Savitsky, Lahtiharju etc all provide some form of correction equation for displacements other than the 100000 lb.

Thanks in advance for your help!
