General


Can iSailor determine my position using external Bluetooth GPS receivers?

iSailor can determine position via the majority of external Bluetooth GPS receivers using the Apple iOS Location Service. Pair your iPad and a BT GPS device via the Bluetooth and select 'iOS' as the Primary Positioning Source in iSailor settings.

Subscriptions


What is iSailor's Internet AIS Service intended for?

The Internet AIS service provides you with online detailed information on surrounding AIS targets of the following types: AIS Class A, AIS Class B, AtoN (Aids-To-Navigation, virtual or real) and Shore Based Stations. The service displays targets within 30 mile range and is useful for boaters who do not have AIS Class B receivers on board. To use this service, you will need to be within the 3G/4G network coverage. Before subscribing to the Internet AIS service, please, make sure, that your area is covered at AIS coverage

To use this functionality you will need to have a WiFi, 3G or 4G/LTE Internet access on your Apple device.

Why is Marine Traffic or a similiar app (ShipFinder, VTExplorer etc) showing more ships in my area than iSailor?

Marine Traffic shows ship positions and courses that can be 1-12 hours out of date. iSailor only shows ship positions and courses that have been updated within the last 30 minutes, which makes it more suitable for navigation purposes.

Can I use the weather service without Internet?

Internet connection is required to view the weather forecast. However, the Weather Player makes it possible to view the upcoming weather forecast for selected parameters. You can download the weather forecast for a given chart window, that will be stored in the application's cache and that can later be played offline.

Can I have my purchases and subscriptions restored on Android if I used to run iSailor on iOS?

Unfortunately, at the moment this cannot be done due to the fact that AppStore and Google Play are two application markets completely independent of each other, which makes it technically impossible.
