For years, we used Maxsea v126.96.36.199 interfaced with our Furuno NavNet 2 chartplotter as our main tool for all our navigation requirements. This amazing software allowed us to do route planning, optimize our route based on weather patterns, show AIS targets, overlay Furuno radar onto the charts, etc. Although working perfectly, the software is now quite old and MaxSea stopped all support for this software back in 2014. It was time to upgrade our navigation software and we bought the latest TZ Navigator v3 from Chris Metcalf, Bluewater Books and Charts. Chris has been most helpful and after calling him on WhatsApp, he sorted me out in no time. I've been testing the software for the past couple of days and I must say it is so much better than the older MaxSea v188.8.131.52. Here is a short introduction video of TZ Navigator v3.
