Marine Navigation Lite

Marine Navigation Lite is an offline GPS chartplotter that puts you in command of your maritime journeys. Unlike subscription-based apps that charge yearly fees, this navigation tool is yours to own and use indefinitely—no hidden costs, no forced renewals. Since 2009, sailors, fishermen, and coastal explorers have relied on this independent platform for trustworthy offshore navigation that prioritizes your privacy.

Start with Marine Navigation Lite to learn the essentials of digital navigation. The free version gives you a genuine feel for the interface and core features. When you're ready to unlock the full suite of tools, you can purchase the complete offline chartplotter once, or upgrade to the PRO subscription for advanced capabilities and continuous feature updates.

The full version delivers everything serious navigators need. Download official charts from NOAA (both Raster and ENC formats), ESRI satellite imagery, OpenSeaMap data, and bathymetric maps to navigate with confidence far from any cellular signal. Set unlimited waypoints, plan routes, track your position, activate anchor alarms, and switch between true and magnetic compass modes. Basic weather information and moon phase data help you plan around conditions, while GPX import and export let you integrate charts and routes from other sources.

For professional-grade navigation, the PRO subscription unlocks a custom S57 renderer—a proprietary engine built from the ground up to display official Electronic Navigational Charts with the speed and detail that once required expensive marine systems. Upload and georeference any image—scanned paper charts, satellite photos of wrecks, even historical maps—and transform it into a fully navigable, offline chart in minutes. Overlay multiple maps with adjustable transparency for the level of control that competitors cannot match. Global offline tides calculated on your device provide accurate predictions anywhere on Earth, powered by the FES2022b high-precision model. Fish Forecast, a new feature, helps plan fishing trips using Solunar data combined with real-time fishing weather and ocean conditions.

Your data belongs to you alone. This app does not track your location, analyze your movements, or sell any information to third parties. Everything you save—your waypoints, routes, custom maps, and fishing spots—remains encrypted and private on your device. You maintain complete control over your maritime knowledge and secrets.

Marine Navigation Lite respects good seamanship practices. While this tool provides reliable offline navigation, official charts must always be consulted alongside this app for safe passage. Download Marine Navigation Lite today and take command of your voyage.
