Argo is a boat navigation app you can actually use for free. Not a trial. You get NOAA charts and U.S. Army Corps of Engineers depth surveys for US waters, 500,000+ marinas, anchorages and fuel docks, hazards reported by other boaters, and routes you plot yourself, with ETA and fuel use. On your first trip, open the map to see how deep it is and read what other boaters say about the anchorage before you drop the hook. A hundred trips in, you're checking how old the Army Corps survey is before you run a shoaling inlet, or laying out a few route options and picking one underway. Think of Argo as the boating buddy who knows every good dock bar and never asks for gas money.
