qtVlm - A fully featured navigation and weather planning program

This is new.. this is GOOD.. and we're now making charts for it !

Introducing qtVlm

Cross platform: Windows, Mac, Linux and Rasbperry Pi (free) plus Android and iOS (paid versions)



In late 2017 we were approached by gifted French developer, Philippe Lelong of Meltemus.com to see if we could make our Unified Charts compatible with his program qtVlm.  We looked, we were amazed, and with lots of co-operation we are going to be making chartsets available not only on the Unified Charts platform (so users can give it a try without giving up their current favourite programs).  BUT also making charts available for qtVlm across all platforms.  First time VMH has ever done this.

So what is qtVlm ?

It's about the most fully featured navigation program we've ever seen !  But not only that, it's a weather routeing program for racing types.. AND a yacht racing simulator.

Most VMH members are cruising types, so we'll concentrate on the features of most use to you...

  • Fully NMEA compatible. Hard wired or WiFi
  • Full instrumentation (analogue of digital displays)
  • AIS display and alerts
  • Routes and Waypoints ETAs all the usual stuff.
  • Anchor Alarms
  • Ablity to download grib files..weather and tidal stream.. (and calculate courses using them for racing types with polar diagrams for their boats)
  • Import/Export data.

Finally... from mid April 2018 our Raster chartsets are available for this remarkable program on all platforms inc Raspberry Pi. At our usual low prices... available NOW.

Some extra detail:




Can use your onboard NMEA instruments..wind, depth, speed, etc


AIS targets by "real" on board AIS receiver  OR for shipwatchers via the internet in near real time.


For those with Windows machines (who may also want qtVlm on Android or iPad)   UNIFIED CHARTS from mid April 2018 also support qtVlm (as well as the already supported programs and apps.)

For those with Macs, Linux, RaspberryPi etc.. We now make CROSS PLATFORM charts that'll work on anything that qtVlm will run on.  These are the very cheapest way of getting "Desktop" licensed charts.. prices from £15.95 for all UK/Ireland ! CLICK HERE

Do not let the complexity of this program put you off when you read the manual:

Get the program HERE   Note the currently available version is compatible with VMH charts, and worth having a very good look at.

We will soon be working to provide some simple tutorials to get the average user started.  More in-depth features can be ignored till you get used to it all.  It's looking to us that qtVlm could be used for many purposes.. even ship routeing, race organising,  long distance support.. all sorts of things.
