You might not want to hear this but I think you are going the wrong way completely.
Your first choice should be to put in a NMEA 2000
network and demand that each piece of equipment
you buy, regardless of brand, is fully compatible with that network and the other equipment connected to it.
This means you need the new generation gear
. We're talking sensors and displays separately.
There is a lot of choice but some choices are no-brainers:
0. Maretron cabling system, using their free design software
1. Wind instrument: Maretron WSO-100 ultrasonic
2. GPS: Maretron GPS-200
: Maretron SSC-200
4. Depth/speed/temp triducer: Maretron DST-110
The triducer is made by Airmar actually and you could buy it direct from them as well. Almost every brand gets their transducers from Airmar.
0. There will be other brands that are good for cabling components but Maretron is as good as it gets. They have the 4-port hubs, T's and pre-made cables
in about any length, plus the parts
to make them yourself. The free software
is another big reason to go with Maretron; it assures you trouble free operation, documents your system and simplifies getting the needed parts
1. Wind: The WSO-100 has no moving parts, is affordable compared to old tech, has air temperature, relative humidity, barometric pressure, wind speed and direction. No more damage from birds!
2. GPS: high speed updates, plenty channels, very quick to aquire lock, always keeps lock, cheap
3. Expensive like any good compass
. But you don't need to buy the Simrad
compass for the autopilot
anymore. This compass also has sensors for roll (heel) and pitch
4. Three sensors in one thru-hull fitting. Just hook up to the network cable and done, perfect.
This doesn't give you a single
display yet. But that choice is easy as all the new ones will work. You need the multi-function LCD with N2K connection. Many disguise the name of that connection by calling it CANbus, SeaTalkNG, SimNet etc. but it is all just NMEA-2000 and work fine. Some popular brands: Garmin
, Furuno, B&G, Raymarine, Maretron. Some, like the Raymarine, can even display AIS targets.
If you want to connect a computer: the Actisense adapter is best choice for that.
I think all modern chartplotters support the NMEA-2000 network. Basically, you make a choice for which radar you get later, if at all. I think all the new plotters are good so just check which charts
are good for your area and which plotters support those charts. I would prefer Furuno, B&G or Garmin
