Trinity Star is a Nelson 42, now just over 40 years old. I have owned her for 12 years and in that time have steamed over 7,000 miles and done a great deal to her including fitting new engines and stern gear, rewiring, re-plumbing and several changes of electronics.
In 2014 the navigation system was upgraded to the Raymarine eSeries display, Class B AIS and a new fishfinder module, and in 2015 it was the turn of the autopilot. I had fitted the Raymarine 400G autopilot soon after I bought the boat and it has performed flawlessly for all these years. It can steer the boat better and with less effort than I can, particularly in following or quartering seas when the Nelson can be a bit twitchy.
After some experience with the new Raymarine EV1 heading sensor on another vessel, I decided to upgrade with the expected benefits of more accurate heading information and a better display on the p70 controller as well as improved autopilot performance. The improvement to heading information should in turn lead to better performance on MARPA, which is very dependent on stable and accurate heading information.
