With the huge network I have on Grace, capturing everything that is going on in a useful form is sometimes difficult. For individual trips, I usually grab the track points off of my Raymarine or take a screen shot to remember things by. While at anchor or at the dock, it’s harder to gather info to do analysis or just show what was going on. In the past I’ve used Kees Verruijt’s great canboat system to dump raw NMEA 2000 via a linux machine to analyze later, but converting them to something useful has always been a challenge.
After installing a Yacht Devices Text Display last year, I noticed they had a product that might help me with my constant quest for getting data off the boat – the Yacht Devices Voyage Recorder. The product records all data off of your NMEA 2000 or SeaTalk network to an SD card. The resulting files can be copied to a computer and analyzed in various different ways – generate maps of your travels, look at performance of your boat, create a polar analysis, and more.
