Gutting a 45' sailboat

[Ketch79]

Hello! I just bought a 45' bruce roberts sailboat for very cheap, an older man was selling her because he couldn't keep up with maintenance. The interior is infested with cockroaches and is very dirty. My plan is to gut the entire interior of the sailboat and re-do it myself. My main concern is with the size of this boat, it has air conditioning (don't think it works) and many other electrical equipment I'm not too familiar with. I would love to take out anything electrical, gut it, repaint / fix up anything that needs to be fixed, and start on doing the interior the way I would like. To live on of course. I have a time frame of about 3 years and was wondering what a normal time frame of gutting a sailboat is? Thanks for the help!
