Good stuff if you don't want to buy a Garmin

I bought this app instead of buying a cheap nav system for my jet ski. I have a full waterproof case/enclosure for my iPhone. I keep it in the front glove box. It works great, saved me around $250 but some of the features/settings and readability of the maps/charts can be irritating when you just want to quickly check your direction and location, especially in smaller connecting inlets around the inter coastal water way system. If the App creators are listening, perhaps you can make a quick reference button and leave the full fledged charts on this app to the sailers and bigger boats. I don't regularly read satellites, so something like google maps but for smaller boaters would be great.

Almost all you need

This has been my favorite app for sailing. I use it for trip planning and navigation. I have used it to navigate through narrow, unmarked channels using the earth view to help guide my boat. My only issue is that the weather radar overlays the chart, making it hard to read when there is heavy weather in the area.
I have this app installed on my ipad and now use it for everything but depth and autopilot. I can see the future of blue tooth networking and no need for fix-mounted nav equipment .
PS. For ipad users, a one gallon zip lock bag is a perfectly fitting, cheap way for moisture protection.

Amazing app

Used this app with my" Bad Elf " Bluetooth GPS system . We had a Raymarine chart plotter on the 45 foot sailboat we chartered out of St Petersburg,FL. Our setup ( Bad Elf and marine charts app ) worked way better than the boats Chartplotter, which was 5 years old and not updated. With this app and the " Bad Elf " we had complete control of our navigation durning our trip off shore and through the narrow channels like Pass A Grill sailing to Gulfport. Plus it was fun and easy to use. It worked flawlessly , blue tooth connection instantly to app, and no jumping or crashing of the app
