INavx navigation software with Navionics charts - some problems, but because we were set on having Navionics for the South Pacific, it was the best option. Livia and her co-captain Carol Dupuis cruise aboard their 35-foot Wauquiez Pretorien Estrellita 5.10b. Windyty is a very useful weather-planning tool. This is handy and hard to see on normal GRIB files, or without IR sat imagery. Among other things, like wind, gust, rainfall, clouds, etc., by looking at the “rainfall accumulation over 10 days option” you can visualize the Intertropical Convergence Zone (ITCZ) and South Pacific Convergence Zone (SPCZ) and extra-SPCZ zones near the equator. Windyty is a web-based application and is a great tool for looking at the big weather picture and seeing the flow and patterns on a more global scale before zooming in on the more localized level. Not as good for plotting and editing routes as a traditional charting program, but for a convenient real-time tool it is rather appealing. We have used it reliably from South America through the South Pacific islands.
