I would like to know if any of the WOA members work with a laser scanning device suitable for scanning into digital format the hull of a W32? 

The idea would be to have the hull in digital format and then use software to analyse water flow over the hull with and without modifications. 

Look at the area below in red - I wonder if fairing this area would result in better hull performance if so - what modification to the area would be both workable and cost effective? 

I've thought about this in the past. I remember reading some time ago on cruiser's forum about someone making a "measured scan" of their hull. They setup a horizontal line between external mounts. Then from this they hung a solid plumb bob line that could be used as a stationary object from which to measure the distance to the hull from the plumb bob using a perpendicular line..

Starting at the bow, they took measurements going down the hull every 6", then moved the plumb bob aft 6" and repeated. It rendered something like 900 measurements 

That's a lot of measurements, but the person was able to put it in to some program and create a really accurate rendition of the hull.

The 3d printing is a great thing!, the bronze parts may need a second step (sand casting of the printed part)  But cool none the less, however for the pins this may not be the way.

As for the 3d scan we need to get it better than 1/16" ;  1/120" would be better to make the effort useful.

Aaron the tape measure is good, but sag, out of level, miss read, and miss location of read would doom the effort to way more than 1/16" error

Along the 3D photo scanning line I would ask?

Has anybody done any scanning with the TRNIO app? if so, how accurate?, how big?

I may try this app  next time, at the Boat? If it works out, I will share. But I do not have high hopes of a good scan = less the 1/16" miss measure with the photo scan without ref grid or shape.
