First, I don't care for touch screen electronics
Terra Nova has a Furuno
makes good radars and because West Marine
had their display unit on sale
for $1,000. It is unimportant that all electronics
be from the same maker. Her SSB radio
is Furuno only because I happened to find a deal on an unused one from a private party. The rest of her electronics either came with her or were used take-offs that I had salvaged. Even her electrical
distribution panel had an additional column of breakers added, courtesy of a take-off panel.
It is uncommon, perhaps impossible, on even the most expensive and tastefully done yachts, to find all matching brand electronics. Nor is it desirable to restrict your choices to only one brand.
Through your own due diligence, discover which companies are best at each electronic specialty. For example I would trust Icom VHF
, Furuno radar
, Garmin GPS
, etc. Then watch for a deal.
