There are three main modern tools you can use, versus the old days: You have a radar system, you have a speed log, and you have GPS.
All of those tools have serial outputs on them, good ol' RS-232.
So here was the concept: take a PC and make a custom "ice breaking" UI, taking input from the three devices, and rendering it in such a fashion that the icebreaker skipper could get all the info in one place.
