The can-j1939 Linux Kernel module does all the heavy lifting involved with the protocol which sits on top of CAN and allows you to easily send and receive messages with hardware devices already supported in Debian Linux (ex: CAN Bus Analyzer from Microchip). This module enables pulling that data and feeding it to a chart plotter such as OpenCPN. In simple terms, seeing a chart is nice, seing a chart displaying your position and that of other boats is *very* nice, having an alarm go off when a process detects a collision is eminant is *pure awesomeness* as it can literally save your life.
