    Hi there,
    There is an option for that in general config, routes tab (Beep when routing/simp/etc)

    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.
  • Re: qtVlm thread

    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
    Board » Technical Support
    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

Sail Around Turkey 2025


Welcome to the 11th running of one of Sailonline's most iconic races, where our fleet races the length of the Turkish coastline from Hopa (the easternmost harbour on Turkey’s Black Sea coast) to Iskenderun (the easternmost harbour on Turkey’s Mediterranean coast). It’s a 1,372nm race and aboard our classic, 1st decade of the 21st Century, version 2 IMOCA 60, you should be able to get around the course in less than a week. That is if, of course, once you get out of the Black Sea you don’t stop to enjoy the sights or a BBQ or two in the Golden Horn, or on the Marble Islands, now land-locked Troy or Gallipoli or any of the myriad Aegean islands, that you shall have to carefully navigate past.

Brisbane to Keppel Tropical Yacht Race 2025


When the winter weather turns cool in southern Australia sailors head up to the warmer waters of The Great Barrier Reef and the big winter regattas at Hamilton Island, Airlie Beach and Magnetic Island. But the race isn’t ‘on’ this year; nevertheless, Sailonline is inviting all racers from RQYS and beyond to race the 343 nm for the fun, this time in our SOTO 40. It might be winter downunder but do put on your shorts and t-shirts before you sit down behind your devices to get into the spirit of it all!

Haugesund to Reykjavik 2025


In late April 2016 Draken Harald Hårfagre, the worlds largest viking ship built in modern times, left her home port in Haugesund, Norway and sailed off for a challenging voyage across the North Atlantic Ocean.
The aim was to explore and relive one of the most mythological sea voyages – the first transatlantic crossing, and the Viking discovery of the New World, more than a thousand years ago. History tells us about the Viking explorer, Leif Eriksson, who discovered America over 500 years before Christopher Columbus. The expedition was all about exploring the world, just like the Vikings did.
Sailonline is racing the 1000 nm first leg, from Haugesund, Norway, to Reykjavik, Iceland in our Farr 400. Let us sail in the wake of history on this epic adventure!

Africa by Sea - Swakopmund to Maputo 2025


Time again to continue our exploration of Africa by Sea, which now takes us around the tip of the continent at Cape Agulhas and up the coast of South Africa to Mozambique’s marvellous Maputo, where we should find good anchorage in the bend of the Rio Espirito Santo (Umbuluzi) once we’ve cleared the 60m high Maputo - Katembe suspension bridge. It’s 1900nm and we’ll be glad to be sailing our comfortable and sturdy Xp-55, as we will certainly experience more headwinds!
