    Here is the polar data for the not-the-V2 Trireme, that will work in QtVLm

    An argument between Poseidon and Aeolus has been resolved and your rowers will now be able to row at near as damn it 2kn, even if Aeolus ins't playing ball and the wind drops to zero. Use the revised polar below if you want to consult the god Qutyvelomis.

    If you want Qt to row you into the wind, use the attached.

    Some recent rhymes...

    On Bimmer's win.

    Oh, Bimski, Bimling, Bimmer,
    By Thor, you'll be our winner.
    Not east, you said, look'd best
    No, Odin, said you, said West
    And you'll be home for dinner.

    On FastFlo's return (and cheese and beer).

    Kediss Fastflo, wederziend aangenaam
    Dutch cheese is barely worth a damn
    Compared to the monastic Belgian brew
    That knocks you out, before the loo
    Is got to.

    On Dingo's driving.

    Wǒ bù zhīdào zěnme xǐ, John
    Hurry up, or El'll be gone
    At a tighter Tee Wee Hay
    As the Chinese just might say.
    Gone direction rising sun.

    My agenda is not so much a concern with ever more and better forecasts, but a concern with the rough-and-ready nature of global_gfs, our standard 'go to' weather. The question and the challenge I want to raise is 'Can we do better?'.
    For the long distance ocean races, this question is not so important, as, out in the middle of the ocean, modulation for whatever should change little to a forecast, and because guessing what is the best thing to do given the uncertainty about what the wind will really be a week ahead will continue to be a challenge for SOLers.
    It is the races of say 3 to 4 days maximum that I feel/find are or have become somewhat mathematically deterministic. You have to have the tools to do the math, but once you have such tools working for you, a race becomes primarily a "do" exercise.

    That is a very interesting article, Dan, but I suppose it all depends on what NOAA consider 'accurate' or 'correct', when it is quoted to state 'a seven-day forecast is accurate around 80% of the time' or 'a five-day forecast is correct approximately 90% of the time'. One can imagine that the assertion is correct about something like 'it will rain in The Peloponnese tomorrow', but, as we know from experience, it doesn't imply that the wind strength and direction forecast for 120 hours ahead at a specific lat/lon posn will be re-forecast as exactly the same 6 hours on, now 114 hours ahead.
    I would like to think that that sort of accuracy will remain impossible for very many years yet. So, that aspect of our game - forecast volatility and second-guessing the met service - is not much at risk, IMO.
    I do agree with you that once gribbed free-issue forecasts become available with a frequency of every 3 hours, it would reduce the attractiveness of our game if the game were to fetch these every 3 hours as well. I see little reason (though not none) for simply keeping our own fetch frequency at 6 hourly; especially if 'accuracy' has improved anyway.
    Indeed, I would suggest it could mean an opportunity to reduce our fetch frequency to every 9 hours, which would give everyone around the world a midnight WX every couple of days.

Round Round Robben Sprint 2020
Welcome to South Africa! It's the end of spring here, so let's get racing, in our brand new C2R74 sled, designed by renowned naval architect Mark Mills specifically for our 2021 virtual Cape Town to Rio Race in collaboration with the C2R Race 2023 committee, slated for early January. This 26nm sprint, conceived by stalwart SOL-ling Saffie Sebensa, takes us round or about Robben Island and then back along the teeming beaches to a finish just outside Cape Town Harbour. Eyes ahead!

The Odyssey 2020 - Leg 3
Leaving a blinded cyclops behind, Odysseus is immediately blown off course again, now to Pantelleria where Aeolus gifts him a bag of wind for later. Sailing on, he next reaches Telepylos, which could be back on the African coast or present-day Favignana off north west Sicily. Our Leg 3 opts for Favignana, which turns out to be inhabited by Laestryonians who start to eat the crew. To get away, the wind bag is opened too soon and they carene on north to the land of the sorceress Circe, who turns the remaining crew into pigs for a year. But once more they get away, finally in the right direction, passing the Sirens on the coast of present-day Amalfi, to end up in The Underworld, the island Vulcano. 550 exhausting miles of mayhem!
