I have been using the Maxsea Time Zero for the last 2-3 years. This software has many advantages.
-It integrates with Furuno Navnet 3D. If you have a license for the Explorer version and use a Navnet 3D system onboard with charts that you already have paid for, you automatically get a license for two PC when buying the software. No need to buy additional charts! Great to have the PC as backup if your plotter would stop working. As a bonus you can also control your radar from the PC.
-The software works with, Navionics, Jeppesen, S57 or raster charts from Mapmedia. Same as with the Furuno Navnet 3D plotter. If you thought raster charts is something from the past, you should take a closer look at Time Zero. You will be surprised how nice a raster chart can be presented. Vectorized charts are nice but it is nice to have a raster chart to check against when in doubt.
-There is also a great Grib file service included. Grib files will be sent to you as an email attachment.
-One of the best features is the integration with ActiveCaptain database. Just create a membership on Activecaptain. Then enter the username/password in the Maxsea software and sync the database when you are online. After syncing you have thousands of anchorages and marinas all over the world with reviews on your PC, displayed on your electronic chart. It is like having an extra Pilot Book onboard. No need to be online as the information is stored in the PC. Do not forget to share your anchorages.
-You need a PC with Windows OS. Unfortunately no support for MAC. But it is working if you run parallels and Windows on your MAC. If you are not a computer geek it is better stay with a PC as you then have full support. The irony is that Maxsea started as a MAC software many years ago. The support from Maxsea is excellent.
Make sure that your computer meets the technical requirements listed on Maxsea web page. You need a decent graphic card.
