Hi all, i am viewing a 2013 SO 33i at the weekend. The boat is being offered for sale within my budget, but looks to be light on spec and equipment, particularly electronics, chart plotter, auto pilot etc.
I would want to put the chart plotter at the helm, and, whilst at it, add AIS, ideally receive and transmit. I'll investigate further with the broker, but what is likely to be pre-installed from new by way of NEMA2K cabling and power supplies etc? or just cable ways to pull through? Or is it a really invasive job, stripping headlining internally etc to pull cables through. Just trying to get a feel for the size of the job.
Whilst asking it would be good to know owners experiences generally on this boat and any specific things i should check.

My boat is a bit older, a 2004 Sun Odyssey 35. I have had a relatively easy time adding electronics, since Jeanneau provided ample conduits behind the cabinetry to run cables between the nav station and the helm. I would be very surprised if they did not also provide this in the 33i, since it's a newer design.
I seriously doubt that there is a NEMA backbone running through the boat unless there are also instruments that would use it. You could get a hint about this by determining what instruments are at the helm. If the speed and depth (surely they are present) are provided with instruments that use NEMA sensors, then there might be a chance. If they use direct-wired sensors, then its unlikely that a backbone is present.
The advantage of not already having a chartplotter is that you would have the opportunity to choose the one you want. A number of members of the forum use a tablet loaded with Navionics or another charting app. Even if you didn't want to do this as your final solution, it would be a way to get started at much lower cost and effort.
As for AIS, the simplest (though not necessarily least expensive) way to add it would be to replace the current VHF with one that has this function built-in. I personally have just a receiver, and I find this adequate. I don't often sail in areas with commercial shipping, though if I did, I would probably have opted for a full transmit & receive AIS unit.

Don, thank you.
There are Raymarine i50 depth/speed/log and wind, which i think are NMEA2K compatible but not on a network themselves, so looks like I'll need a backbone. That looks straightforward enough, just a case of working out the cable routes.
Further question - 230V power sockets - again i cant see any in the photo's, the 33i owners manual i have found online suggests these might have been optional. As far as i can see, shore power supplies the water heater and battery charger from a small consumer unit in the locker - but i can only see one cable going out boat-side. Does this serve both? And is there a spare way for providing a supply to sockets?

I can’t answer your questions about AC power. A 33i owner might be able to help. When you see the boat, check the electrical panel for breakers related to outlets. Even if they were optional, there might be support for them, in which case they would be relatively straightforward to add, even if you had to hire an electrician.
Of course look look for the outlets too. Perhaps they’re already present.

My 36i is much the same vintage and access for running wires was quite easy. Panels can easily be removed and. replaced as they were screwed on and screws covered with dome caps. I have mounted a 7" chartplotter in a pod at the helm along with autopilot and depth/wind etc display. The unit is small enough to not crowd the area and large enough to work very well. Having the plotter at the helm is great when sailing into unknown anchorages. I expect you will find a couple of unswitched 230 volt outlets.
Hope it all goes well, Rob

The i50 has Seatalk and Seatalk ng connections so it is very likely the transducers are connected via a Seatalk backbone. |

The i50 has Seatalk and Seatalk ng connections so it is very likely the transducers are connected via a Seatalk backbone. Reading the i50 documentation, it is clear that you have a choice to connect transducers directly or through the SeaTalk(ng) interface. However, doing the latter requires an i70 master unit in order to calibrate the transducers.
It would be an easy matter to look at the back of the i50 instruments to see whether the transducers are connected directly. Even if they are, the speed/depth/log (i.e. Tri-Data) unit is most likely connected to the wind instrument in order to be able to compute true wind. In this case, you will have a SeaTalk(ng) backbone, but it will very likely be very short and located in the immediate vicinity of the instruments.

On the 33i there is factory power cabling to the binnacle from the navigation switch. All cable runs on mine have mouse lines in and are easy to pull through.
Ac sockets on mine are above the electrical switches port side, above the upper cupboard in front of the sink and one under the cooker.
Nmea network fitting is dependant on what the dealer fitted.
