Mary,
We did just that several times at the Gaulden Reed Summer Sizzler. We took pictures of each boat at the A mark on the first day. Took the film to CVS that night and had the pictures the next morning. Sort the Pics by class and sail number so they are easy to find once the scoring has been done. Just insert the pics into plastic frames with place stickers. The rest of the pictures we put out for the sailors to keep. Low cost and everyone had a great memory.
