    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

    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.

    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.

Carib Rum Run 2026


Ahoy, ye landlubbers and seasoned salts! Welcome back to Sailonline’s legendary Carib Rum Run, perfectly timed to kick off on International Talk Like a Pirate Day, 19 September!

This year, we command the magnificent Falkun—the ultimate high-tech superyacht modeled after the iconic Maltese Falcon. This 1759nm slalom takes us through the Caribbean’s rum islands to plunder barrels from local distilleries and deliver them to the rum-parched sands of Cancun.

Join SYC before the finish to disguise yer boat with a pirate name for this race only. Hoist the sails, sharpen yer cutlasses, and plot your winning course!

Silverrudder 2026


Ahoy, SOLers! Welcome to the 2026 edition of the Silver Rudder – Challenge of the Sea! This epic 125nm single-handed race around Denmark’s island of Funen is back!

Shallow waters and shifting winds await in the world’s largest solo regatta. This year, we return to the popular First 27 solo. This superlight, water-ballasted planing machine features twin rudders and weighs a full tonne lighter than her older stepsisters. Will you master her power where precision counts most?!

It is imperative that you read AND understand these special Starting Conditions for SILVERRUDDER 2026:

Isle of Mull TIMED Race 2026

Welcome to the west coast of Scotland for an 80 nm race around the Isle of Mull. Mull is home to castles, distilleries, and the Highland Games. The race begins just north of Oban in the shadow of Dunstaffnage Castle and after rounding the island finishes down the coast at Crinan. The Twister 28 with its classic long keel is the boat for this race.
This is a TIMEDrace so you may RE-REGISTER HEREto try again after finishing a run. You will have two weeks to test your skill and decision making after the race opens.

Cross the Convergence 2026 - Cocos to Sagar Island


Kapil Muni, incarnation of Lord Vishnu, founder of the Samkhya school of philosophy, disturbed from his meditation, in his wrath reduced the 60,000 sons of Sagar to ashes, as they dug the earth to retrieve the sacrificial horse that Lord Indra, the king of the Gods, stole off Sagar, thus creating the Sagara (ocean). Aeons later, Bhagiratha, a descendant of Sagara, asked Ganga to cleanse the ashes of the 60,000 princes, and her resultant torrential fall from heaven created the great river and where it met the ocean, the princes’ souls were washed and raised to heaven and Gangasagar (Sagar Island) was formed. So, let us join the pilgrimages to Kapi Muni’s Temple (see above) and race 2400nm from Cocos Island deep in the Sagara thence, in rather rapid Rapido 60s.

Shearwater - Rio de la Plata to Irish Sea 2026

Welcome to the fourth leg of our MIG series. This time we're racing the Sooty Shearwater on their migration from the breeding grounds in South America to the northern Atlantic. This is also part of our Ocean Championship, and as such the third race of OCQ3 2026. This race will be sailed in our Gunboat 90. Race #2055
