A98 ST50 ST60 Quantum Raystar 130 "suite"

[kevkal]

Hello Charles,

Very much appreciate the service you provide on this forum!

I'm trying to set up a new "suite" of electronics for my boat.

The boat presently has:
- ST60 SmartPilot autopilot and fluxgate compass
- ST60 depth instrument with the lexan transducer

They work well and I plan to keep them.

I have purchased some new equipment:
- A98 display
- Quantum Q24C radar
- CPT 110 bottom sounding transducer
- Raystar 130 antenna
- Seatalk ST1-STNG converter
- Standard Horizon GX2100 VHF radio with AIS

I also have some older ST50 instruments that I'd like to install with the new gear. They include
- ST50 wind speed and direction
- ST50 depth (for use as a repeater)
- ST50/ST60 compass heading (have both)
- ST50 boat speed (no transducer)
- ST50 NavData

Goals:

1. Be able to sail with the A98 and autopilot off and still be able to use the ST50 and ST60 depth, compass, wind and speed instruments, as well as get latitude and longitude from the ST50 NavData instrument.

2. Be able to sail with the A98 and autopilot off and still be able to use the navigation and AIS functions on the Standard Horizon VHF, which requires a latitude and longitude input from a NMEA interface.

3. Install the CPT110 transducer inside the hull (perhaps in an oil bath) but keep the present ST60 lexan transducer thru-hull so that I have both.

4. Use the ST50 Speed instrument as a repeater that displays only calculated SOG (presumably from the Raystar 130 antenna...I don't want to have a thru-hull speed transducer / paddlewheel.)

FWIW, I'm not too concerned about displaying AIS data on the A98 if that is going to be difficult.

I've attached a block diagram of the sensors and display components to aid in thinking about the system. Essentially it lays things out geographically from bow to stern:
- vicinity of the mast
- nav station
- companionway
- helm
- stern

Your thoughts on the "reasonableness" of my four goals above and any related thoughts would be much appreciated!
