In the basement at home I had been stripping, sanding, and re-glueing various cabin parts. Today the first coat of varnish was applied in the AM. In the afternoon it was back down to the boat for continued work on the head area. Pictures below.

I was apparent that water was allowed to lie in the aft section of the boat as the keel, ribs (attached to it), and the garboard planks (located adjacent to the keel) had deteriorated through the years and were in need of replacement. It was determined that the aft 9 feet of the keel needed to be removed and replaced. The keel is 6 inches wide and 3 inches thick made of white oak. With a scarfing ratio of 8 to 1 meant we needed to make a 24" scarf. We used a skill saw to cut off the keel after the 2' needed to make the scarf. The next step was to create a jig with the proper angle to achieve the 8 to 1 ratio/angle. The router base need to be modified to allow the router to travel up and down the ramp. A scarf of this length took about an hour to complete going at a depth of 1/4" increments. Below are pictures of the process.
