My B36 is the fourth boat that I have owned, and in comparison with the other three I'd say that Bavaria have done a better job by far in regard to the control panel than on those other boats. What I have here matches the neatness of layout of the control panels on any of the ships that I worked on during my seafaring career, including three ships under construction where I joined the ships during the fit out period and so have first hand experience in regard to seeing quality workmanship in action.*
Like Mark and Lyra, the only poor workmanship and poor quality installation I've seen on my present and previous boats has been the result of third party installations either by owners or after market suppliers of additional electrical or electronic equipment.
In regard to the wiring of the auto-pilot, I fitted my own, but I followed the instruction provided by its manufacturer, Raymarine, to the letter. In that respect and on my system, the power supply for the drive motor was taken directly from the course computer which had its own specific terminals for that motor. There were also separate terminals on that computer for connecting to the Seatalk communication system, and specific instructions to ensure that there was only a single supply of current to that communication system. The drive motor was very specifically not powered from the Seatalk system which does not have the ability to handle the kind of current that the drive motor requires, and which I'm sure would completely mess up any chance of the proper operation of the Seatalk communication system.
The only negative points that I have found so far in regard to the factory fitted electrical system has been the use of ordinary copper wire where that was provided instead of the much better tinned copper wire, and where as a result it suffers from corrosion. And the other negative is a rather skanky automotive cigarette lighter style of power point on the 12v distribution panel, where that and various power plugs that need to fit into it for recharging portable electrical items, also tend to suffer from surface corrosion.
*PS, they too only used ordinary untinned copper wire where the length of cabling used was measured in kilometres and where no doubt using tinned wire would have added considerably to the cost.
