Hi
Now there are the difference between old and new technology --- if you
talk about a Cyber-Boat you can scale it all directions all you want,
but you need to scale it "equal" that mean double length double hight
double wide , if you want it out of equal scale you would need to ask
the designer to make the calculations as doing that make foults in the
unfolded panels.
Doing the same with tradisional drafting methods is a hell of a job
even you scale equal, simply all drawings need to be redrawn where
things like stability with a 3D drawing, is a matter of "asking" what
the stability curve now fit.
I could ansver your question about tar and oakum as I acturly master
the art of caulking the old fasion way , but please forget about it you
will not need it true it is an interesting issue but only for real
oldtimers , -- you don't want to listen to the story if you don't want
someone spitting tobacco all the time.
