And never forgets his chart either. - Why Argo Navigation? - Let’s be honest: most marine chartplotters and other GPS software are either clunky, confusing, or so expensive you feel like you’re buying the boat all over again.

Not Argo Navigation. - Effortless Marine Navigation, Charts and GPS - Plot nautical routes directly on Argo Navigation’s map and enable GPS tracking with just a few taps. We include up-to-date NOAA charts and Army Corps of Engineers data covering the US, Canada, and the Caribbean, including coastal areas and many inland lakes. - Plan Boat Trips with Confidence - Hidden anchorages, waterfront restaurants, or the nearest fuel dock? Argo Navigation’s boating map has it all, plus reviews and tips from other boaters. - See Marine Weather, Tides, Currents, and More - Overlay NOAA weather and wind on your boating map, and analyze marine forecasts well into the future. See tides, currents, temperature, wave height, and wave period across the US, Canada, and the Caribbean. - Stay Connected to Your Boat Club or Community - Share voyages, swap boating tips, and see where fellow boaters are cruising. With Argo, the sea feels a little smaller and a lot more fun. - What’s Included with Argo Navigation: - • Unlimited Charts: Access charts for the US, Canada, and the Caribbean, including coastal areas, the ICW, inland lakes, and rivers. • Interactive Nautical Map: Find marinas, anchorages, boat ramps, restaurants, dock bars, and more. • Voyage Logbook: Plan, save, and relive your voyages with detailed logs and trip memories. • Real-Time Local Knowledge: Crowdsourced hazard reports, depth updates, reviews, and insider nautical tips from boaters like you. • Community: See where fellow boaters are cruising and plan trips together.

Routes are tailored to your boat’s draft and height. • Offline Charts: Download offline charts and routes before leaving the dock so you can navigate confidently when cell service disappears. • 7-Day Weather Forecasts: Tides, currents, wind, rain, lightning, temperature, wave height, and period. • Custom Depth Contours: Adjust contour depths and colors to visualize safer waters and identify ideal fishing areas. • Sync with Your Chartplotter: Import and export GPX files for easy navigation. • Multi-Vessel Support: Manage routes and logs for all your vessels. - What Boaters Are Saying - “This app is a game-changer.
