Need help with product compatibility

[sdemore]

I just picked up my first sailboat, a C&C 30, in project boat condition. It has no electronics aboard, but has what appears to be an ST50 wind sensor on top of the mast and a pipe through-hull transducer (metal pipe filled with epoxy and wires coming out). There may be more that I haven't dug out yet.

I assume that these connected to some kind of Raymarine instrument, but I don't know what they had in there. I need to install a chartplotter anyway, so would like to find one compatible with these sensors.

Any suggestions on how to verify the sensor types (attaching photo of the wind sensor) and determine what products would be compatible?
