    R.I.P. J24Opla
    Board » General Discussion
    Yesterday we received the sad news that Claudio (aka J24Opla) sadly passed away.
    Claudio was a great sailor, mostly appreciated in the lakes Maggiore and Garda and also a very active member of SOL community. Unfortunately he became very ill and COVID was not nice to him.

    May he rest in peace and sail away in smooth sea.

    Still shocked by the terrible news! Had quite a few professional chat with Joao and I will remember him for is clear and concise way of thinking. Like to remember him sailing, IRL or virtually, with the same spirit!

    will you?

    Well Done! It was the right decision to make. One of the reason SWR is the main event of SOL year is that we really get to test ourselves against the top navigators. And with 18 hours of headstart (and a totally different wx configuration) it would have been a pity to race this one on our own.

    Thanks to the SRC and management for the reaction in such a short time!

    It appears that we are starting despite the new postponement of the IRL race. I am in total disagreement with this decision as it makes incomprehensible the first postponement. Hope that the SRC can reconsider and delay the start accordingly.

    Re: The Weather Research & Forecasting Model (WRF)
    Board » Technical Discussion
    In synoptic conditions, i.e. wind given by large pressure systems, forecast are simpler and more reliable (see the Bos-New race with the heavy storm). In fluky conditions, with basically no pressure gradient, wind is given by "local"effect such as cloud coverage etc. So yes, on mesoscale, weather is less "consistent".

    As a comparison, GFS is "averaged" over a much bigger gridsize, so all the small scale variation are zeroed and you ave a more stable but less interesting windfield. On the other hand NAM model, on a 0.1deg scale, has the same behaviour.

    JB,
    at present time we have to allow for some WX data outside the race course (the purple line). This to allow predictor to work properly in the client. In this race we have used 0.5deg from each side. In the end we had more than 30% of datapoints "useless" for the race. In an optimal condition (no points outside race area), wxfile should have been around 4MB, which travels compressed now, so perfectly usable for the "desktop" client.
    Regarding mobile, probably it has some problems (depending on hardware) regarding memory and cache. Probably Zappe can look into that.
    Finally, the WRF is defined every hour, so dataset is 3X for the same resolution compared to GFS. As outlaw commented, we should push for even higher time resolution (1 frame every 15min). In this case probably we'll have denser frames for the first 6hrs and sparser afterwards.
    Ciao

    so, you are referring to the grid discretization.
    In SOL this changes from race to race. Usually we start from 0.5x0.5 deg GRIB file from NOAA which is then interpolated to the grid of our interest. In Leg4, for the first time, we are running the ocean on a 1x1 deg grid. The "pointy" edges are caused by the interpolation algorithm (bilinear), which is the same we use to get wind in between grid points.
    The WRF model we are using in the BOS-NEW race is evaluated on a much denser grid. This is not an interpolation process but a complete physical evaluation. The 0.5degx0.5deg GRIBS from NOAA are taken as boundary and starting conditions then the calculations are done on a powerful computer. The result is a 0.05X0.05 deg GRIB.

Lake Ontario 300 Challenge 2025

Lake Ontario Offshore Racing (LOOR) welcomes Sailonline sailors (SOLers for short) to a second virtual version of a race in their annual series, the LO300. As the name implies, the LO300 is a 300nm offshore race across the length and breadth of Lake Ontario, from and back to Port Credit YC. Once again, as is our wont on Lake Ontario, a fleet of Beneteau First 36.7s is being made available to virtual racers. There is an overall prize for the SOLer who best bosses Lake Ontario over the two races hosted by Sailonline, this 300 and the Susan Hood raced back in May; so, let the competition be fierce!

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.
