Taking the Lines of a 1979 37C - or obtaining the original drawings?

I recently acquired a 1979 Hunter 37 Cutter (Hull #23). It's been neglected, and I'm looking at a lot of fun challenges.

I've found some line drawings online, apparently scans taken from an owner's manual, of the original layout of various ship systems in plan view. I'm fortunate that my roommate used to work for Boeing as a technical illustrator. He's helping me bring these 72dpi graphics into the 21st century, creating editable Adobe Illustrator files I can edit to reflect changes in the ship systems during the refit for better communication with any subcontractors, or just for my own records. He's asked me if it's possible to get better than 72dpi drawings as source material to work from, so we can do a better job with making bow, stern, and port/starboard elevations.

This got me to wondering if there's some way to get drawings showing the original lines of the hull, as would have been used in making the mold, for example. Having those lines would also make it easier to generate an accurate 3D model. Some of our ongoing projects for the boat might benefit from being able to create accurate animations of the 3D hull in motion.

I've read some articles about taking the lines from an existing hull, involving laser measures, scaffolding, etc. I'm just hoping there's an easier way. Does anyone know how I might be able to obtain those original lines in a reasonably high-quality graphic format?

Thanks in advance!

Lifting the lines from a boat can be done. There is a technique.

On YouTube Bob Emser recently had a video where he took the lines from a half-hull to draw the lines. The process is the same, just bigger devices.

I had some correspondence years ago with John Cherubini II (Diana of Burlington on this forum) about getting access to some of his dad's drawings. As I recall it, he had the line drawing of some of the Cherubini-designed Hunters that he was hoping to be able to publish but I got the impression that there were some intellectual property rights tangled up with Hunter Marine. I have no idea if Marlow acquired the rights or if they still have the old drawings (which would have been on vellum/mylar, not CAD files). Good luck!

Thanks so much for this - I got in touch with John, and he may be able to help with drawings of the 37C, if he's got them, after returning home. Fortunately, he knew the previous owner of my Hull #23, and has some valuable knowledge to share about this and that...thanks again!
