Of course try without the hub. Also try with different cable, if you have one. Preferably with FTDI chip which is generally better and not faked that often.
What I would do myself would be dumping the conversion to USB completely and using the UARTs on RPi (They are 3.3V TTL, of course you need something like MAX232 in front of them, or better a RS-422 equivalent if the Raimarine thing follows the NMEA specs)

The raymarine interface does have a nmea out thats going to my ICOM vhf (gps for DSC) and to the AIS data input. I'd like to use this RS232 for ease of use.

I've ordered new FTDI based chipset cables for now.

i just swapped serial/usb cables, and everything just works, no errors, no checksum clashes....all good. im ordering some higher quality ftdi chipset cables now.

thanks all for the assist!
