Dream on.
I own a 1992 Passage 42. When I found the inverter was powering the electric water heater, I called Hunter and after calling back twice, I was told by Joe Kerr (yes, I had to have him spell that because of the way it sounded) that they had no schematics of the boat wiring because "they just had a guy that walked around on the shop floor and told people what to do and how to do it".I found this almost impossable to believe but it has been basicly confirmed since then by a seperate source.My wife and I have spent many days pulling wires and using an ohm meter with 10 ft leads to draw a partial schematic of our boat.It's a shame that Hunter hasn't entered the 20th century with their documentation.
