Not to hijack the thread - but since Raymarine was mentioned in context with this...
My 25 year old CC cruiser doesn't have a wind transducer.
Maine - what I hear you saying is I can put a TickTack transducer on the mast, plug the T122 interface to the ActiSense NGW1, hook that to the RayMarine NG network which is interfaced via my e7d.
The benefit here of course is no wires up and down the mast.
Raymarine SeaTalk NG Networking
I won't have any seatalk1 devices so I don't need the e85001?
The only other things I'm adding in are going to be the autopilot (raymarine x10 with a st70 control head), sonar (airmar p79) and eventually radar (also raymarine).
