Go to that site and click on Penn Yan on the left-hand side. Your canoe could be the Hunter model, although it seems the Hunter is a 15 footer.
If this doesn't appear to be your boat, we'll need to see pictures. If you have a way to get pictures into your computer, they can be posted by scrolling down to the box below this one and clicking on "manage attachments"... you'll get a browse box.
Prior to the computer age, people would sent photos to the WCHA historian or the head of the nearest chapter. If anyone wants to send pictures to me, I can scan them and post for All to see.
