Only for Netherlands
Response from developer
Thank you for trying our app! This app is for viewing and sailing with any charts our users have in their account. We do offer charts for all coastal regions of the UK, both Stentec and Imray charts: https://www.stentec.com/nl/kaarten/kaartoverzicht. If you have any questions or problems, feel free to contact us at stentec@stentec.com
Limited Charts
Response from developer
Thank you for the feedback. We developed another app, WinGPS Marine Plus, which gives you the option to directly download the NOAA charts in the app. This way you can use these free charts of the US waterways. You can find this app in the AppStore.
