Thank you for the reply to my message. My electronics
packaged has evolved over 30 years that I owned the boat and the only electronics that are still in use are the B&G hornet: speed, log, wind and the Hecta Depth
. They do not talk on NEMA and are from the "stand alone instrument" era.
Nowadays all electronics are talking on what is an N2K or equivalent network. This has many advantages... but for my next upgrade when the Hornet and Hecta bite the dust will hopefully be a wireless "network". Wires and water
are not friends in the end.
Of course an entire suite with cockpit repeaters is quite spendy and with my more or less stand alone devices working there is no reason to drop a lot of money
for electronics which really doesn't give me much more than I have or more importantly what I need. I have several GPS units and the 2kw radar is fine for my use.
I find AP integration a potential hazard and it makes the sailor lazy. I prefer to take all the data from my "transducers" and with the chart and the current
and weather information select the course to steer. As a sailor is constantly tweaking their sails
... this is not integrated yet ;-)... why not tweak your AP heading as required??? All I do is turn the little dial a tad to port or starboard.
Tech stuff can be very seductive. I used it every day but I don't understand it and can't fix these things.
The Alpha has served me very well. I recommend it as a robust not integrated AP. My experience in some deliveries with other pilots was so so. I love the course dial on the Alpha as opposed to punch in numbers.
And wired networks have a great time with a lightning
strike... integrating all the damage!
Over time I advanced my "position fixer" electronics from Loran
to GPS and eventually to a NMEA 0183
RayC80 which can be integrated but is not the current
generation. The N2K is a network and as such there is no CPU as there is for the C80.
