We use navionics for navigation and the windy.com app for wind and weather. Interested to see if there are any other good ones out there that we should be looking into. I’ve seen some people using the predictwind app for route planning but it’s kind of expensive.
I have a SignalK server running on a raspberry pi that I finally got hooked up to my instruments via a nifty hat (sailor hat). I’m excited to try out the anchor alarm feature. Hopefully it’ll be less prone to false alarms about my anchor dragging than my phone.
I’ve been using the Signal K anchor alarm for a couple of years now. Very reliable so far. But of course only as good as the GPS source of your system.
