You can give OpenCPN a look: https://opencpn.org. It's a nice chartplotter with lots of plugins.

Posts created in portrait mode automatically rotate to landscape mode. This is something across Lemmy that seems to be known. To address, the image must have the correct metadata, not just rotated in your camera roll before uploading.
This looks pretty compreshensive. Have you used Navionics before? If so, how do you think it compares?
I've used Navionics too. I feel like OpenCPN is less intuitive but more configurable. In general I prefer free software so it was my first choice.
Windy for weather.
In Finland, Sailmate for the official sea charts.
We sailed with Navionics for several years, but now switched to Orca. Better AIS, weather routing, clearer charts.
Thank you! I’ll have to look into Orca!
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.
Yep, Navionics and windy are where I tend to start, but the two that I tend to spend the most time in while route planning are Qtvlm and OpenCPN.
Qtvlm's route planning capability is pretty good once you get into it a bit.
I use windfinder for wind. But honestly I like windy more but I think it cost something(Or I don't know). Than I also use WarnWetter(for Germany) It has wather reports and warnings as text but you have to pay once for the weather reports but only one or two euros. And for denmark I use DMI (oficial danish weather app) as from what I heard a few years ago Denmark uses a more pricise weather model than some other apps at least for the danish region. Navigation I do only on paper but maybe I will try some aps in the feature.
