GPS & Instruments – Real time and Simulated display of current LAT/LON (position), SOG (Speed over Ground), COG (Course over Ground), BTW (Bearing to Waypoint), DTW (Distance to Waypoint), VMG (Velocity Made Good), XTE (Cross Track Error), TTG (Time to Go) for waypoint and entire route, a satellite graph and a NMEA monitor. GPS data can be repeated to another device such as control of an Autopilot. Additional instrument data (Heading, Speed, Depth, Temperature, Wind Angle and Windspeed) is also displayed. Having all this information literally at your fingertips, assures that you remain informed of your position and course.
Charting & Plotting – Current position with velocity vector, waypoints, routes and track history are plotted. Seamless quilted vector or raster chart scrolls keeping current position centered. North up or course up orientation. Chart may be displayed with low light viewing intensity. Click on any object on the chart and see complete details. Search and scroll to any object on the chart. Chart can be “marked up” in any color. No more marking, erasing and remarking paper charts… know where you are, where you’ve been, and where you’re going!
Install any or all ENC S-57 chart catalogs from US NOAA. Value priced chart download service renewable in-app subscription.
Chart sets organized by the 9 US Coast Guard Districts.
Just select your region and HelmStation automatically downloads and installs.
Automated updates always keep you safe with the very latest official charts.
Zooming & Scrolling – Show chart at scales between 1:2,500 and 1:20,000,000 zoom with excellent clarity. Rectangle zoom select to display any part of the chart. Scroll with chart drag or arrow keys. Easy zooming on double click, touchpad scroll, pinch, & zoom gestures, mouse scroll wheel, or select direct zoom level.
Waypoints – Create, edit, drag and goto. Waypoints include a name, icon, and description. Waypoints can be saved, exported/imported and transferred to/from the GPS. Waypoint positions can be displayed in several user selectable formats. Flexible Waypoint usage makes it extremely easy to set a course for intermediate destinations, or to return to previous ones. Found a great fishing hole or anchorage? No problem… save it to a Waypoint for future reference.
Routes – Create, edit, drag and goto including auto advance. Routes include a name and total distance. For each waypoint in the route the bearing and distance from the previous waypoint is given. Routes can be saved and transferred to/from the GPS. Flexible routing features make it very easy to plan a trip or to repeat a previous trip.
Track Logging – Log and plot historical position automatically at user selectable intervals including course, speed and instrument data. Track can be exported/imported and transferred from the GPS. See how efficiently you sailed your course. Use this information to implement changes in future routing.
Measure – Position, distance and bearing (true or magnetic) anywhere on the chart including great circle routing. This quick, easy, and accurate method of measurement makes paper chart measurement an antiquated methodology.
Built-in Alarms – Available for Anchor drag, Waypoint arrival, Cross Track error, Shallow water, and AIS/Radar vessel proximity. Both visual and audible cues are provided. User selectable range. Have you ever tried to sleep on the hook during foul weather, while wondering if your anchor was truly fast? Don’t depend on luck and guesswork. The integrated alarms add an additional level of comfort in knowing what’s really going on.
AIS/Radar – Automatic Identification System receiver displays local vessel traffic including name, call sign, length, speed, course, distance, destination and closest point of approach. RADAR shows tracked targets if sent over NMEA (not high def overlays). Both AIS and RADAR are plotted on the chart. AIS transponder can be used.
Weather – Using readily available and free GRIB weather forecast files, wind speed, wind direction, wave height, wave direction, current, pressure, precipitation rate, air and sea temperature are plotted on the chart. Choose the date and time of the forecast you wish to see. Knowing the forecast helps make key routing decisions.
In App help provides quick answers to most questions regarding configuration and use. Easy access to assistance will ensure that you quickly become a master of even the most complex program functions.
On-line app help docs available from the app and our web site too.
Google Earth Export – Plot waypoints, routes, tracks and weather in Google Earth. Friends and family can easily see your plans and progress with Google Earth on a Mac or PC.
TCP/IP Interface – Send and receive (TCP or UDP) NMEA data over wifi.
Apple Maps Integration – Control click on any chart location and launch Apple Maps straight there. See satellite views. See street views. Find that perfect destination, send to your phone, then hop in the dinghy and you’re ready to go!
