Download and install

What are all these packages?

On Windows, the easiest way is to take the full "Full release for windows" (qtVlm_full.zip file), which contains all the elements needed to run the program. Other packages ("Binary for windows" and "General structure") only serve to limit the size of the download when you do not want to update a part of the program.

A == Where can I install QtVlm? ==

Anywhere on an internal or external drive, a USB key, on the desktop or elsewhere. The easiest way is to copy the file qtVlm_full.zip where you want to install the program and unzip it in the same place. This produces a file "qtVlm" in which the program is located qtVlm.exe launch. ( See here)

A == Where do we put the cards QtVlm? ==

The full version is already provided with a deck of cards (Grades 1-3) located in the directory "qtVlm \ maps \ GSHHS." But you can load maps more accurate and, after unzipping the file, add all the resulting files in the same directory. ( See here)

I == error message after launching an update (win_exe.zip) ==

Must unzip it and then retrieve the executable qtvlm.exe and copy it into the directory QtVlm. ( See here)

Before installing the new version, you must uninstall the old one?

  • Simply load the win_exe after decompression and place the new qtVlm.exe instead of the former ( See here)
  • You can also load a new version Full and placed twice on his record
  • To keep its old settings, you must recover files qtVlm.ini, and boatAcc.dat poi.dat and copy them to the new installation of QtVlm.

Troubleshooting and Problems

No server connection VLM

  • ' 'Case 1: The weather map is changing, but my boat is not moving more:

1. Change server:

- Options \ Settings VLM \ Advanced \ Url

- Select s10 s11 or

2. Reregister his boat:

- Setting boats \ Select the boat \ Delete \ OK

- Login \ Password \ Add \ OK

3. Recreate his route:

- Routes \ Creating a new route

- Recreate its roads (providing, for convenience, the same names as before the failure).

4. After changing server reinstated his boat and recreated his way, everything returns to normal: the boat moves forward again found its WPs.

It remains only to re-materialize the road to the WPs reraccordant!

  • ' 'Case # 2: I can no longer start QtVlm

Manually change the server:

- My Computer \ C: \ Program Files \ QtVLM \ qtVlm_full-2.1 \ qtVlm \ qtVlm.ini

- 'QtVlm.ini' contains configuration settings: change the value of 'vlm_url':

vlm_url = 0 for the server S10

vlm_url = 1 for the server S11

  • Warning! It is possible that the two servers VLM is available between 1:00 and 3:00 UTC. Therefore think take steps by programming the security pilototo VLM!

I wanted to transform == point-route-QtVlm in WP-A VLM for my boat and it became my VLM WP-B on another boat race: ==

Your map centered on your boat route A.

You have changed the way point following in WP-VLM by using the right-click function on a point-route, then 'Brand -> WP'.

The point road in question turned from black to red.

But you later found that it was your boat B, embarked on another run, heading towards the WP-VLM!

The most likely explanation is the following:

You selected, initially the boat B in the drop-down menu in the toolbar to work on the road to B.

Then you went to the boat's A by using the command right click on the map, then 'Center map here' to see your boat and work on A Road A.

Unfortunately, before sending your order 'Brand -> WP' VLM, you forgot to select the A boat from the dropdown menu and it is entirely logical that the WP is came to register the account of the boat B remained active!.

  • 'Tip: Before you place an order from QtVlm to VLM, be sure to check the drop down menu is selected the right boat!

I replaced the original polar fleece and forced my way materializes more

You will need:

1. click 'Routes'

2. 'Edit a road'

3. select your route

4. in the Settings window, click on 'Submit'

The road originally scheduled will reappear!

I can no longer download the file zyGrib 7 days via the Menu bar \ GRIB File \ Download

You certainly have version 2.1-2. The functions 'download' and 'Info file' menu 'File GRIB' do not work on this version.

You need to install the latest version, instead of or in addition to your current version.

How can I easily loose 73 places or more at the end of the VLM Vendee Globe Race?

Learn about Waypoints and Routes and Autopilot control.

What happened. I ran aground. I sent a good route to finish the race to the autopilot using VBVMG. I did not check that the last waypoint went between the gates and woke up the next morning with the boat hard against the French shore. I had to create a new route to finish and lost 75 places.

Why did this happen? The boat probably made it to the waypoint, but did not cross the finish, so what happened afterwards? Once the boat reached the waypoint, it appears it continued sailing, but in what direction? Was it still using VBMG? Why wouldn't it have gone towards the finish line (next waypoint) or perhaps just stopped at the end of the route and sent an alarm? Does the program have some of these choices? Answer from Maitai:

The VLM My Waypoint documentation states: "If no value has been filled, your Way Point (WP) is the next mark, provided lat,long are entered as '0'. When you complete (lat, lon) values in the 2 text boxes, the next race mark is forgotten until you reach your waypoint. "

  • First of all, a WP is considered as 'reached in VLM when the distance beween the boat and the WP is less or equal to the distance the boat sailed during the previous crank (vacation). So in fact the WP is always reached *before* the boat hits it.
  • After a WP is reached, what happens depends on how the WP has been set-up:
    • If there is a "Heading-to-follow-after-WP", then the boat will be set in heading mode with this value. Nice, but if the wind happens to come from that direction, you might not move a lot...
    • If there is no such value defined in the WP (i.e. it has been set to "-1"), then the boat will keep the same navigation mode (VBVMG, VMG or ORTHO) as the one it had before reaching the WP, using that mode toward the closest point of the next race gate. Nice again, but if there is land between the boat and the next gate that might create problems

Follow up:

There is no way to find out, but I unknowingly probably had pilot instructions set on a "Heading-to-follow-after-WP" because the boat went ashore, rather than -1 to continue to the closest side of the next race gate (the finish)!

There is an option in qtVlm for that and probably this is what happened to you. By default qtVlm will set "heading-to-follow" with the last direction that the boat was sailing when the WP was reached and deactivated.
