even more rot

Will the rot ever end? Down deep in the bow the keel is rotted, whoever had this boat before me must have tore off some of it before because about half of it is gone. My plan is to use CPES, soak it in, then build it back up using ? and also, I'm wondering if I should perferate the rotted keel so the CPES will have a better chance of penetrating all the pores and wood cell cavities leading to, hopefully a strong keel.
