I started this thread and thought I would provide a follow-up to the original post. After a little bit of work, I was able to get the boat off of the trailer and up on its side in my garage. From there I was able to inspect the keel strip more closely. With nothing more than rough sandpaper, I was able to remove the damaged wood with little work. What I ended up with was the original keel mostly intact except for the front third whose edges were a tad more rounded. Since the damage didn't seem that significant and since summer will be here and gone quickly where I boat in northern Minnesota, I decided not to replace or scarf in a new section. Instead, I decided to layer on wood flour fortified epoxy in some of the most damaged areas. After this had set up, I also put a coat of carbon powder infused epoxy over the whole keel area. I also patched over two rectangles where the paint had been rubbed off a little ( from the trailer? I don't know.) with the same carbon epoxy paint. The carbon epoxy idea I got from reading something on duckworks. A lot of people swear by the stuff. I'm attaching pictures in the next post. You will see a rather ugly job since this is the first time I've worked with epoxy in this type of application. Drips are everywhere. Next time, I will. be more careful and use tape and newspaper to cover areas I want to keep clean. I'm going to see how this repair holds up over the summer and then possibly repaint the whole bottom this fall. Thanks for all your help.
