NavShip is a free navigation assistance software for nautic usage in Europe, Canada and the United States. It uses an special overlay for google maps or open sea map to show shipping signs and contains by now more than 500 waterways.
No problem to get from A to B, even if there's an ocean between you and your target. London - Rome, Paris - Amsterdam, Copenhagen - Stockholm, Frankfurt - Istanbul, Chicago - Toronto, nearly every route can be calculated.
Offline maps still is in beta phase but works in parts with lower quality open street map.
NavShip needs access to device's storage to work properly. It never accesses your private data or contacts.
