I'm at the tail end of completing this in CAD (I use SolidWorks for those who are curious). The proportions are bugging me because it's real close but I still find areas that don't quite line up with images. It's difficult to get the angle and perspective right though to make a good comparison. Trying to go back in the CAD history and tweak something creates errors that can take a few hours to fix. I think I'll leave this where it is and start cutting the plugs. LOA is 70.5", 12.7" beam. The beam is too big (from what I've found these were 8' in width), but I'm not going back at this point. This is one of the things that is really bugging me.

I have a smaller sized CNC router so I'm going to have to make the plug in sections.

Perspective is wrong in these next ones because it's actually at 1/8 scale in CAD at this point and the perspective doesn't work well. The center drive is supposed to be shorter and they're a little fat in proportion simply to get gears in there that will hold up.

This was a portion of the first layer for the plug but after going back into CAD and updating a few things this will change.

The beginnings of an outdrive. Again, proportions are off but I have no choice. I'm going to see about making gears out of stronger material to get the proportions closer.

I do have a family and of course a job, so I can't guarantee frequent updates. I am itching to get this going though.
 
Nice work! I think she looks good.
As you mentioned they list the beam on a 47 at 8’2”. All the Cigarettes I have measured are slightly wider mid ships than the transom, most likely carried over to the Apache hulls also.
I can probably get more measurements on the Apaches if needed.
A few I have done over the years, 38 Bertram, 35 Cigarette. 👍
