I am doing a multi-season upgrade to more modern sailboat nav electronics.
--Garmin 741xs Chartplotter with Radar, nothing else talking to it, installed a couple of years ago.
--Raymarine ST60+ Tridata Depth/Speed/temp with transducers directly connected.
--Autohelm ST6000+ head with Type 300 computer and below decks actuator
Right now none of the above are interfaced. Now, my Raymarine speed impeller has bit the dust. I want to replace it with a speed impeller transducer that will talk directly to the Garmin 741xs, and while I am at it, put in an depth transducer to talk directly to the Garmin 741xs.
But...I'd like to keep the ST60+ to repeat the Depth/Speed/Temp rather than spend over $500 for a new display that will do the same thing. I'd also like to have the Autohelm interface with the Garmin.
I'd like the flexibility to add wind and AIS in the next year or so as well. Is this all doable, or am I asking for a problematic and messy jumble of wires?? I'd like guidance on the least expensive and most effective way to do all this.
I would like to have the ST60+ repeat the
