Below are scanned images of the basic plans for Sarah as provided by Pearson Yachts to Sarah's first owner.  To see an enlarged version of these plans click on the images.  As I convert these drawings to AutoCAD I will post them in my AutoCAD page.
As you can see these 30 year-old blueprints have seriously deteriorated, which was the main reason I attempted to scan them into my computer.  The individual plans were much too large for my 9"x11" flat bed scanner, so I scanned it in one 9x11 chunk at a time and then merged the chunks together using PhotoShop.  If you look closely at the full resolution images you'll notice that many of these chunks didn't come together seamlessly.

I will attempt to convert these diagrams to a soft version (AutoCAD, FastCAD or Visio) and then update them to reflect the current situation on Sarah.  This will probably take several years.
