NaWi Sail Navi America

Simply select your destination point on the sea map, enter wind direction and wind speed and NaWi will calculate for you how to get there as fast as possible using your sails. It will propose you optimal route (straight or zig-zag) and give you exact time and distance to your destination.

Now with ANCHOR ALARM - alarm watching safe distance from anchor location

The challenge when sailing to windward is to know how high to point into the wind.

When pointing higher, the boat goes slower, but there is less distance to travel. On the other side, when pointing lower (from the wind), the boat goes faster, but the distance is longer. The trick is to find the optimum angle, that balances speed with distance. And that is what NaWi does for you.

Once the optimal route is calculated it is displayed on the map. With simple dragging of tacking point you can adjust the route (e.g. to avoid collision with dangerous navigation points or visit interesting places). Once you are ok with route, NaWi will navigate you to follow your optimal route.

Navigation screen is designed to provide all essential information in readable form even in hard sailing conditions. The rotating compass over the map shows the optimal course, speed, course value, time to destination and time to tack are also displayed. Everything in one place, but easily visible.

Your optimal route is projected on the Open Sea Maps. These can be downloaded to your device in time when you have Wi-Fi connectivity and then used offline during the sailing.

There are no additional purchases in NaWi and you have full functionality available after download. If you want to try it first, there is 14 days free fully functional version available for download here: https://play.google.com/store/apps/details?id=sk.moj.nawi.trial.app
