@ James Vaello,
Where are you located?
I´m from Vienna/Austria - in the middle of Europe with no sea nearby.
You may need to know that I´m one of these ´Old School`- shipwrights…-
means, I don´t know how to use Auto-CAD… still working with the old method of drawing everything on millimeter papersheets.
Then doing the calculations with a simple pocket ruler, then redrawing on another sheet of millimeter paper if necessary.
All the designs shown here where originally done that way.
Only then - via the internet - I found several guys capable of CAD-design and interested to help me out, who then transformed the datas I sent them into dxf.-files.
These persons where - Eric Edel from Germany and Umut Korkmaz from Turkey both for the Nightmare Mk.VII - and Phanchita Supasirithanawat from Thailand for the Nightmare Mk.VIII. - Siri later on then also asked me to do two trimarans for the 65cm size. -
There even have been some students in the past who provided me with 3D-renderings of some of these trimarans. (can be found at www.rcuniverse.com - sailboatsection somewhere.)
I myself never needed them - this was just to present my design ideas online.
As Im European, I´m used to the metric system -
If you are working with inches normally, this could cause some difficulties.
But please note, that each curve I´m using is a parabolic curve,
which is self fairing and can be (re-) calculated with the biggest ease.
The sequences are simply: 0 + 1 + 2 + 3 + 4 + 5 and so forth.
Which add up to: 0,1,3,6,10,15 - and up to eternity, if needed…
or - 0,0.5,1.5,3.0,5.0,7.5…
0 - Zero - are the two mainframes - and from there curves can and will be different fore and aft.
So if you want to redraw the plans, you just need to use the reference sheets with it´s numbers and go from there.
And you´ll know very fast, what I mean!
I myself - by the way - have learned ´lofting-the-lines´ the old-fashioned way. But this has never stopped me from designing modern trimarans.
