You don't need to spend that kind of money
to have a fantastic nav/radar system.
The new Raymarine
plotters look fantastic and dirt cheap
at only $1670 for the the 8" C series one at Defender -- and you get a free i50 instrument to boot! Now that's an incredible bargain. The new Ray digital HD radars are supposed to be very good. The Ray system is wifi
capable so you can view and control the plotter from a tablet computer. For many people, this eliminates the need for a second plotter, saving $2k or so.
I bought B&G Zeus plotters which are absolutely fantastic -- I'm tickled pink. They are more expensive than Ray but are very solid and have more sailing features. Two 8" plotters and a 4G radar
cost me about $6k from Defender. These are Simrad
NSE and NSS clones with added sailing features, for almost the same money
. You can even now buy a 7" Zeus touchscreen plotter for around $1000 -- Navico
are competing hard with Raymarine
and Garmin, which is good for all of us! Another advantage of Navico
(Simrad, B&G, Lowrance) plotters is that you can use almost any cartography of your choice -- Navionics
, CMap, or those bundles from that German company the name of which escapes my mind.
I have never used Furuno
plotters so can't say anything about them. I know that there is a general consensus that the Furuno radars are the best pulse radars you can buy. But I don't think you really need a black box system on a 41' boat. Those are mostly for big power boats where you want a giant separate display on your giant bridge. Do you even have space anywhere for one of the massive displays that go with black box systems? Furuno makes a nice 8" plotter which is only a little more expensive than the Ray or Navico offerings -- something like $2600 at Defender after the $200 rebate which is going on now.
Good luck and let us know what you finally choose. It sure is a great time to be buying marine electronics
-- so get so much more for so much less money than just a couple of years ago, it is amazing.
