Check out the link on the left side of the page "greenland technique forum" Its the site of qajaqusa and is devoted to SOF. Also check out cape falcon kayak. Brian is a kayak genius and has a good tutorial for skinning. Sprit line is a good source of info as well.
Depending on how old the boat is, you will want to check damage. And don't confuse "skin on frame" with canvas canoe. If its simply canvas covering a wooden hull, then its a different beast.
