NMEA 2000 Network Installation - Part One
At the time of purchase all electronics on-board were working (past tense) and separated into three distinct systems:
1. Instruments: anemometer, depth, log.
2. Navigation: Chartplotter, Autohelm, and VHF (for the AIS overlay).
3. Radar: Raytheon RX10 Radar.
So, having read enough books to scare anyone away from sailing, radar seemed mission critical. Further reading on how to use radar I discovered radar assisted collisions. This posed a bit of a conundrum. The riddle would read - you have it to avoid collisions but it also assists in people colliding.
For added confidence on the channel crossing it became the first job we would complete: replacing the very-close-to-your-head 1.5KW brain liquefying microwave device, with a modern small output digital one.
