I'm really confused here the boat if built well is well worth finishing or finding someone to finish her I also am wondering what you are getting at with the leave them the anchor part as to the skeg part it sounds to me at this point have addressed the apparent issue what other issues and questions are you wondering about? As to the deck stepped mast there are several camps on that part personally I am an advocate for deck stepping vice keel stepping with a proper compression post or structural bulkhead to support the stress load to the keel and hull there is no hole in the deck that you need to seal from leakage another person here that would be a treasure trove of information would be Bob Perry hopefully for you he will chime in here as well and thanks faster for your posts here in my absence helped me help the op
