  • Re: Weather - Brain Storm
    Board » General Discussion
    VIbex: The key to my idea is to use an underlying weather model for the simulation which powers our virtual boats that is different from the predictions available to SOL competitors.

    I agree when you say "we're not actually living on the boats so you need some measure of predictability" but I don't think that means we need to be able to 100% predict the weather.

    When the weather is very stable and highly predictable then the models will likely be very closely aligned. In those cases it might be safe to sail very close to a mark or an island, but when the weather is less stable you might choose a wider safety margin over absolute performance.

    As for the question of using 'rules' to control which models can or can't be used, there is always going to be someone who wants to cheat.

    Ideally, I like the idea of using something like a pre-release beta version of the ECMWF model not generally available except to researchers, if such a thing exists. Another alternative might be a psuedo-random merge of multiple model GRIBs ... This could be a fun project :-)

    Also, they explicitly mention not-for-profits in their license selection guidance so you're just dreaming and there's little point in trying to ask anything from them.

    i.

    Is it possible to get access to the ECMWF model for internal use only on the server while using the GFS model in the gribs provided to users?

    It seems to me that this would fit the licencing requirements for the not-for-profit use of the real-time ECMWF data.

    It would also be closer to reality in that the underlying model used on the server would be different to the forecasts available to users.

    There may also be a need for a new SOL rule that makes it illegal to use commercial paid-for products not available to all users for free.

    I think this would make for some more interesting racing.

    14.2.3 doesn't seem to automatically download GRIBs anymore :-(


    Looks like this only affected the Mel-to-Osaka race. Seems to work perfectly in other races. How bizarre!
  • Merge of steering and DC tabs
    Board » General Discussion
    I really like @Zorba's idea of merging the 'steering' and 'DC' tabs. Maybe allow for 8-10 lines of DCs bacause if anyone is using more then they are probably using other tools to generate them.

    It would also help to be able to set an actual time rather than just a delay period.
  • Extended predictors - Suggestion re the hourly indicators
    Board » General Discussion
    Love the new extended predictors. Thanks @ij.

    One small suggestion: Hourly indicators are open circles. Perhaps fill every 6-hourly circle to make a large dot. This would help in interpreting the longer predictors.

    The longer predictors will be really helpful when training up those new to SOL. The curly-whirly patterns can be very instructive.

    This might help explain it:

    Version 4.0.0 looks really good.

    I had all sorts of problems initially but finally got it all sorted. 1st problem was I was using a 32bit instance of Java. Tried the latest 64 bit SDK but no joy. Updated the JRE (runtime environment) and it worked beautifully.

    Thanks Kipper. Everyone will enjoy the updated version.
  • Suggestion re: broader logging options
    Board » Technical Discussion
    Kipper: It would be really useful to be able to log data for all boats or perhaps just those selected for AIS display. Last year psail and I used hmmm's logs to do some post-race analysis on the 2016 Mel-2-Osaka race but unfortunately hmmm's site is no longer available.
  • Re: Performance loss
    Board » Technical Discussion
    There are some really interesting ideas in the pipeline and there is a great team of people working on it. Physical (kinetic) performance loss certainly exists but it's probably not a significant issue in an ocean race. Crew fatigue, on the other hand, is probably much more important. Lots of manoevres (tacks/gybes) will take a big toll on the crew. And doing these in high winds or at night is going to have an even greater impact. So, perhaps double at night; a sliding scale from x1 to x5 from 20 to 50 kts; and a no-go-zone from 50kts+ where you can't tack or gybe at all because the crew is simply refusing to get up on deck.

Abel T Appreciation 2020
In December 1642 after a particularly difficult and rough voyage, the Dutch seafarer and explorer, Abel Tasman, made landfall at a spot he named Staten Landt, believing he had arrived on the coast of Argentina. In fact, he had arrived in modern-day New Zealand. Once again out of love and respect for this brilliant seaman, Sailonline is retracing his route from Tasmania to New Zealand.

Uruguay to Cascais - 2020 RTW - Leg 4
The last leg of Sailonline's Round the World Race 2020 takes racers from Punta del Este, deep in the South Atlantic, to Portugal's Cascais on the North Atlantic seaboard. More than 5000nm of almost only open water, bar three easily avoidable, well-known island groups and Fernando de Noronha and Madeira, in our much-loved Orange 125ft catamaran for your leisurely enjoyment of only wind, wind and wind and maybe some wine, chat and cheese!

The Odyssey 2020 - Leg 1
According to Homer, after the Greeks sacked Troy, one of their heroes, Odysseus, had a particularly fateful journey home. Sailonline now invites you to relive his epic tale, journeying in a virtual ancient trireme, modelled on the Hellenic Navy's real live replica Olympia. The legend tells Odysseus was immediately blown off course, north to the land of the Cicones, perhaps making landfall near Cape Maroneais. When the winds abated and after pillaging the people, he made good progress south, undoubtedly rowing some of the way, to exit the Aegean at Cape Maleas, where this virtual first leg ends. Take your seats for 360nm of tragedy!

San Francisco Bay 2020
Many a Sailonline race has started or finished at San Francisco's Golden Gate, but never have we raced inside The Bridge on The Bay. This 27nm sprint corrects that oversight with a fine sight-seeing tour past Alcatraz, Yerba Buena, Brooks and East Marin Island. Our rarely raced Fox 9.50 is your boat of choice. She's a nippy little thing. Enjoy!

A3 2020 Leg 8 - Darwin to Perth
In 2012 Sailonline lost one of its more remarkable racers, Aaron Gage, the creator of the Flash client and all-round awesome human being. In his memory, Tyger created a superb series of races around the island of Australia - the A3 (Agage's Around Australia) Series. This race is Leg 8 of the series - a race of 1860nm in Orange 125ft Catamarans from the laid back north to the booming mining capital and yachting centre of Perth in the south of the state of Western Australia.
