What sonar are you thinking of using? I’ve had impressive results with the ping2 mounted to blue boat in initial testing…
If windows is a must, you could install a small pc in one of the hulls, but the solutions @Elliot mentioned are definitely simpler and easier. I’ve had good results with a generic sensor, rs485 to usb adapter, and windows topside windows interface software (running on a m1 mac in parallels no less!)
