Congratulations on your new R-29S! I have the same boat (same model, same year). It's a wonderful boat. I'm sure you will enjoy it!
Unfortunately, there is no owner's manual for this boat. The link helpfully provided by another tug nut is for an earlier version of this boat. In 2015 the boat was completely redesigned. Since 2015 no new model Ranger boat has come with an owner's manual (R-29s, R-23, R-27). It is a mystery why such a great company, that makes such a great product has chosen to stop documenting it. It makes life difficult for new owners (this is my first ranger tug).
As far as the boat goes, I couldn't ask for a better fit for my priorities. I don't trailer it so having a 10' beam is a real plus. The forward birth is very comfortable (I really like the fact that you can walk around the bed). I've used it for week long cruising and found it a joy. I easily single hand it and find docking it with the bow and stern thrusters a breeze. The 260HP Volvo will get me to 18-20kts which is about as fast as I need to go. I like the torque of diesel engines!
I've added a couple of features since I've owned it (and will be adding a few more this winter when I pull it out of the water). I've added a second chart plotter (the one that comes with the boat is a garmin model 7212, I've added the new garmin 7612 as a second plotter). Now each time a new generation of plotter comes out I swap out the old plotter and upgrade. I've upgraded the AIS system. The boat comes with and AIS 300 (which only receives), I updated it to the AIS 600 which sends/receives. I've added a camera to the back of the boat (reverse image for backing down) and integrated it into the chart plotter. Helpful when I'm docking but also very helpful to see if anyone is overtaking me when I'm underway. I've also added side view mirrors (port and starboard) which I find very helpful as well.
Best of luck!
