73 Irwin Ketch - The Adventure Begins

[drl620]

I recently purchased a 73 Irwin Ketch which has been "modified" to be more a house boat than sailboat. My chore is to now get her back to sea. Since the previous owner had no paper or plans on the boat, my first need is a set of deck plans so I can identify tank locations, hull valves etc. HELP! anyone got a clue whee to start this search for drawings on this boat?
