Yes, Bluetooth serial connect should be possible, i tried before with NMEA from an Bluetooth GPS Dongle.
its an little tricky to open the serial bluetooth connection before - but after this is solved you can connet to it like /dev/ttyUSB with Openplotter-serial to make the data available.
Look here for older Reports about "RFCOMM" or "rc.local" to set it up at boot time.

But i would prefer real cable connections on an boat, especial so near the waterline.
