I wanted to build from the AP up and have a single
source supplier to avoid tech rep finger pointing. My research
has made me confident that Simrad
builds the best APs and all other system components are top notch.
I then selected the Simrad
NSS MFD over the B&G (both are Navico
units - same hardware
just different software) because I fish offshore
more than race
and the NSS comes "fish finder ready" with Sonarhub that costs a few hundred $$$ to add to the B&G.
I decided on one IS40 multifunction repeater mounted next to companionway
to complement the 9" NSS MFD (plenty big enough mounted in Navpod at helm). Repeater will show wind angle info primarily when sailing and depth
info when motoring into a shallow anchorage. All info also available on MFD.
The AP is not integrated into the MFD so as to avoid a single
source MFD failure leaving me with no ability to connect autopilot. The AP computer and controller are wired into all sensors/GPS for full steering
capability - just not thru the MFD.
Simrad 4G radar
selected for close range resolution and ability to set target warning rings. AIS
info will show on MFD and all MFD info will repeat at nav station in cabin
via Simrad GoFree wifi
to a RAM mounted IPad
Now just need to install and test!
