I was visiting my local sail shop and the Owner pulled in to his shop to show me an old Highlander he had been asked to restore.  I could not find a hull number.  There was a sail bag with #288 on it.  I would like to confirm the hull number.  Where can that be found on the old boats.  Does recognize the sail number and know any history?
 
It's in rough shape but is still rigged as if it came from the showroom floor.
