    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!

    ciao

    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)

    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.

Susan Hood Trophy Race 2026

Lake Ontario Offshore Racing (LOOR) welcomes racers to Sailonline’s virtual version of their annual Susan Hood Trophy Race. This year, this pleasant weekender on western Lake Ontario will be of about 60nm in length, and online for convenience will start and finish at the Port Credit Yacht Club (PCYC). At or before the real-life Skipper’s Briefing a decision will be made to race the course clockwise (course Delta) or anti-clockwise (Echo). If there is time we will match this online. As before, the race is the first of two that will count towards a special Sailonline's LOOR Series medals, but this year we sail in Jeanneau Sun Fast 3300s. Bon voyage!

Vasco da Gama Ocean Race 2026

Welcome to Sailonline’s virtual Vasco da Gama Ocean Race, in partnership with the Royal Natal Yacht Club’s real-life event. Some 260 nautical miles in length from Durban to East London, the Vasco da Gama is South Africa’s oldest coastal ocean race, and is renowned for the rough seas and strong currents that competitors have to contend with. Online this year we will be racing in slick Salona 39’s. History, endurance, camaraderie – It’s time to honour Vasco’s legacy; see you on the start line!

Cross the Convergence 2026 - St Helena to Cape Verde


The fourth race of our series of ocean voyages across the World’s convergence zones takes us out of the Pacific into the Atlantic for a 2200nm race in Judel Vrolijk 62’s, from the desolation of St Helena, there where Napolean Bonaparte saw out the end of his life, to the even greater desolation of Fogo in the Cape Verde’s. You’ll have to cross the equator, with the coasts of Africa and South America your only navigational restrictions.

Tasmania to Kamchatka 2026

Welcome to yet another all-new route. Tasmania to Kamchatka, part of our Ocean Championship and also the third leg of the ROW (Round the Old World) series. Be aware of the obstacles on the way, likely to split the fleet. It's like X:mas to X:mas, crossing the same waters, navigating the same archipelagos. This second race of OCQ2 2026 will be sailed in our revised 'version 2' Imoca 60 Foil. Race #2031
