Full description
For all types of boats. Beautiful marine weather animations: • Crowdsourced wind maps for the most accuracy and highest resolution. • Marine weather forecasts from Weathernews Inc. (WNI) with maps of precipitation, visibility, air & sea temperature, wind, waves/swell & ocean currents. • AI models of ocean currents and marine weather from Amphitrite. There are lots of weather services and apps, but they all use the same GRIB satellite weather forecasts. Low resolution, low accuracy, and only updated 4 times per day. Weather satellites are 500 to 22,000 miles up in space. Crowdsourcing is changing marine weather. In coastal areas, we archive these to map wind flow for more accuracy. Crowdsourced weather maps like these have never been possible before. A wind sensor measures local wind around your boat, but now you can also know the wind and sea state up ahead or around the next point. Discount Bundle: Get our Ultrasonic wind sensor with a free Air Link™. Amazing value! https://wi-rb.com/product/discount-bundle/ FEATURES FOR ALL TYPES OF BOATS: ● View your route with free aerial photos and land maps worldwide. Import worldwide Navionics charts with a yearly subscription. All maps and charts can be used offline. ● Hourly weather tables for crowdsourced wind and WeatherNews Inc. (WNI) weather maps. Tap on a certain hour to move the whole weather animation to that time. ● The weather animations have a low-cost monthly subscription with a free 7-day trial. ● Create waypoints by tapping or importing a list. ● Crosshair icon in the top left is the “Follow-Me” button. If tapped, it turns blue and keeps your location in the center of the screen. Unselect to look around the map. ● GPS track can be displayed under options. Save a screenshot to view or share your trip later. FOR SAILBOATS: Whether cruising or racing, it is important to be able to determine the best heading on all points of sail. GPS chartplotters and mapping apps do not account for sailboat tacking distances. But if they do not know the distance you will travel, how can they calculate your correct ETA? This is the only product that calculates your optimal tacks using your tacking distance and polar plots. Details at SailTimerApp.com. SailTimer gives you a quick and easy display of your optimal tacks and TTD® (Tacking Time to Destination). ● If you have the wireless SailTimer Wind Instrument™ (SailTimerWind.com) connected to your phone/tablet, your optimal tacks will update automatically in this app as the wind changes. Or you can manually enter wind direction and speed to see your optimal tacks for the route you are planning. ● Just select a route to see the optimal tacks to each waypoint. ● When you pass a waypoint, press the > on the right side of the screen to go to the next waypoint. (Press < on the left side to see optimal tacks to the previous waypoint). ● The optimal tacks are the same headings whether you do the port or starboard tack first. See the FAQs at http://sailtimerapp.com/FAQ.html for hints about avoiding obstructions by switching to the other tack. ● Polar plots: The app comes with a default polar plot for calculating optimal tacks (which you can edit). Plus, it can learn the custom profile for your boat's speed on different wind angles (polar plot). ● Wind gauge button in upper right when using wireless Wind Instrument shows True and Apparent Wind Angle and Direction (TWD, TWA, AWD, AWA) in True-North and Magnetic-North reference. ● Audio feedback is available by tapping screen to hear wind conditions. (More audio features are available in the SailTimer Wind Gauge app).

What's new

• Weather routes: You can now display your waypoints/route with a weather map animation overlaid on Navionics charts. • Wind maps: tap a location on the animation to see the GRIB satellite forecast (white), and/or crowdsourced wind measurements (purple). It is fun -- look for the green dotted line and target.
