OpenSeaMap is a worldwide Opensource-project for creating a free nautical chart. Founded in 2009 the project gained a lot of attention lately adding more and more nautical information for free. Not even lights and other nautical infos are provided, but also more and more info layers like weather data, information about harbours and so on.

Ratings and Reviews
Great if pack more features
This is the best I can find for an app that's free and usable. But unfortunately for what I need, it just need a little more. All I hope for is that i can bookmark an location and be able to remove them individually. This app can't even do that. I wish there is that feature, then would at least be a 4 star.
Open sea map
iOS 16.1.2. It’s not usable. Crashes when I do anything.
wheres the chart data?
had high hopes for open crowd sourced charting, this isnt it. for marine navigation, even google streetmaps on sat view has more detail. willing to be told im wrong, but i deleted it after 15 minutes.
