I have a newly acquired Hunter 23 (1987). The boat needs a lot of work. I am currently getting the trailer road worthy so I can move it to my shop. I plan to start at the bottom work my way to the top then rebuild the interior (more on that later). I have attached pictures of the keel. I was only planning on painting. However, after a closer look I have concerns. Where would you start? What should I look for? Looking for advice.
