    Probably NMEA does not like "ö" and similar strange characters

    Thanks Andrew for reporting this so precisely.
    It's fixed and will be in the next version, soon.

    There was an issue, so to say (Murphy's law)
    You can now safely update to 5.9.1-p1

    Very sad news. We had a lot of exchanges to improve qtVlm usage with sailonline.

    All my thoughts to his friends and family.

    Joao, you should also mention that you are using settings that I strongly say you should NOT use...

    Running a routing with 5mn isochrons can only lead to disappointment in most cases. If I allow for 1sec isos would you use it? 1ms even better? Even less?

    Using such a small amount of time between isos creates way too many points that are likely to look useless to the simp process, which can only do what it is aimed to do: simplifying (i.e. remove the point if the ETA is not worst). Since there is not enough room between points it will end up by over simplifying.

    Conclusion is that there is a good reason behind the default values, what else can I say? Modify them at your own risk, but do not complain if you don't like the result.

    I could add a few things:
    1) Routing with 5mn interval on a 3 days travel is just ridiculous knowing that the real wind is different from the grib's wind and that anyhow next grib update will just completely rebate the cards.
    2) qtVlm is not specifically designed for SOL and will never be. qtVlm is designed for real sailors or racers and does not try to give an exact answer to an infinite problem. It is just a toolbox that can help to decide where to go.
    3) qtVlm is also used in official scientific projects and is also used by very famous racing teams over the world. No one is using 5mn isochrons, there must be a reason.
    4) We are opened to suggestions and improvements and even complains. But it need to be reasonably compatible with the real world, and concerning bugs it needs to be reproducible with reasonable settings.

    Happy Xmas to all
    Philippe.

    Hi,
    Thanks for the detailed information. I was able to reproduce that and it's a race condition that can occur randomly if NMEA is on. I fixed that and it's in beta4: https://www.virtual-winds.org/maitai/qtvlm_setup_5.8.6-beta4

    Please test this and tell us if it's OK now. If you or someone else needs this beta for another platform than Windows just tell me.

    Philippe.

    No such problem here, what version are you using on which platform?

    @João/psail what other problems ?
  • Re: qtVlm thread
    Board » Technical Support
    It will, but that is gonna be Alt-B

    In the mean time clicking on the microboard upper label does the same.
  • Re: qtVlm thread

    No idea
    Next time it happens save somewhere boatAccReal.dat, poiReal.dat and qtVlm.ini, and send it to me.

    BTW last version is now 5.8.1

    No idea. I built a virtual machine with exactly the same version as you, no problem here.

Abu Dhabi to Dondra 2020
Almost exactly five years ago, SOL, shadowing a real live ocean race, set a mighty fleet of honed and updated OD65s off on a gruelling voyage from Abu Dhabi to Sanya on the southern tip of China's Hainan Island. A month later, the race closed with half the fleet still out at sea. This year, this January, we re-enact this race, but are putting in a stop halfway, after about 2000nm, at Sri Lanka's Dondra, with the second leg scheduled to start a month later; both to count towards 2020's OCCH series. Fair winds!
