About this app
The fastest current is in the river channel on the Missouri River, and the fastest way from Kansas City, Kansas to St. Charles, Missouri is to use an app that will help you stay in the channel. Virtual Buoys does that. In addition, Virtual Buoys keeps track of how close you are to the Reaper and how fast you must paddle to stay ahead of the Reaper. In short, Virtual Buoy helps you complete the MR340.
Latest release
What’s New
Version 5.4 improves the accuracy of location services. It also lists hazards on the navigation screen if they are designated as such in the event file. It improves the presentation of crossing buoys. Audio alerts have been shortened slightly to eliminate as much surplus speech as possible. Version 5.4 doesn't eliminate any known bugs, because there were no known bugs.
