I've been lurking here without posting for a couple of years, so I know how much valuable knowledge this community has.  Thank you all!

I've built a couple of models of the Hindman Double Ender with Transom based on the lines that Fletcher describes in his book.  The first model was 1:12, and the second ~1:3 and is a rocker for my baby.  Both came out well.

I've also been toying around in Freeship with the lines that Fletcher gives.  I noticed a couple of spots where curves don't appear to be fair, but attributed that to the software wanting to straighten out lines between points.

Lastnight I drew lines for another model of the HDEw/T, this time it is 1:12, but reduced by a factor of 0.8 along only the x axis (length).  I am finding that there are at least two offending points to drawing a fair curve: Station #1 height to chine seems to be too low when drawing the profile (z axis), and Station #9 seems high.

I have gone back through my numbers, and all I can come up with is that there is a mistake in the source data (the book).  My question is this:  When lofting a boat, is it common that you find minor errors like this?  Follow up question:  What do you do in such a case?  Pick a point that makes the curves fair?  How do you then adjust the frame angles, lengths, etc?  I think I'm probably overthinking it and should trust the wood to correct some of this for me.
