Catamaran Cruising

<font face="Arial, Verdana"><span style="font-size: 10pt;">I had tried OpenCPN out on a Rasberry PI, but had not persevered!.&nbsp;</span></font><div style=""><font face="Arial, Verdana"><span style="font-size: 10pt;">My preference is for Weather4d (</span></font><a href="https://www.weather4d.com/" style="font-family: Arial, Verdana; font-size: 10pt; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal;">https://www.weather4d.com/</a><font face="Arial, Verdana"><span style="font-size: 10pt;">) for getting and viewing GRIB files.&nbsp;</span></font><div style="font-family: Arial, Verdana; font-size: 10pt; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal;">Its a bit complicated, but worth exploring in these times when we cannot actually sail.&nbsp;</div><div style="font-family: Arial, Verdana; font-size: 10pt; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal;">You can choose different grib areas and sources. I have one very small data set that is suitable for downloads over 3G, and another - much larger file that included tidal data that I download when on WiFi.</div><div style="font-family: Arial, Verdana; font-size: 10pt; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal;">I use it at home regularly to see what the weather is going to be like.&nbsp;</div><div style="font-family: Arial, Verdana; font-size: 10pt; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal;">Today's view on the "wind" view below, but we tend to look at the "precipitation" more when we are at home.</div><div style="font-family: Arial, Verdana; font-size: 10pt; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal;">Weather 4D "plus" also does route planning and can take into account tides and the yacht polar characteristics.&nbsp;</div><div style=""><font face="Arial, Verdana"><span style="font-size: 10pt;">But for&nbsp;</span></font><span style="font-family: Arial, Verdana; font-size: 10pt; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal;">passage planning you cannot beat Neptune Navigation's passage planner.

I do not "Android" so have not tested the new android app in depth, but I would expect it to work well- but be aware that a recent Android "update" did cause problems (details all on their website).
