    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.

Roma Giraglia Regata 2026

Our eighth race of nine to celebrate all things Mediterranean - fickle winds, history and olive oil – is another buddy-up; this one with the Circolo Nautico Riva di Traiano . Founded in 1984, as the new Traiano yacht Harbour neared completion, the Circola since then has developed into one of the major yachting competition centres in Italy, and next to the 450nm Roma per Tutti (which SOL buddied earlier in the year), the Roma Giraglia Regata is its other headline offshore event. First raced in 2005, the 210nm course takes competitors from Traiano to a rock on the inside of the Ile de la Giraglia off the northern tip of Corsica and back to the Italian mainland for a finish in the bay of Santo Stefano. We’re racing this one in our Class 40!

Arctic Tern - Greenland to Antarctica 2025

Welcome to the fifth leg of our MIG series. Now it's time to race the Arctic Terns, on their migration from Greenland to Antarctica, 8300 NM. This is also part of our monthly Ocean Championship, and as such the first race of OCQ4 2026. This race will be sailed in our Maxi Trimaran. Race #2061

Bornholm PYOC


Welcome to the Baltic Sea, where we are about to hold another sprint race. The course runs from the north to the south of the beautiful Bornholm island. There are only two waypoints, the start and the finish so the choice of which side of the island to sail along is up to you. Our Albin 79s will cover a distance of approximately 23 nautical miles.

Cross the Convergence 2026 - Masirah to Chagos


Having crossed, re-crossed and re-re-crossed the Convergence Zones of the Pacific and the Atlantic, we now face our second crossing of the Convergence Zone of the World’s third great equator-spanning sea, the Indian Ocean, taking us from the channel between Masirah Island and the Oman mainland to the Chagos Archipelago. It’s 1900nm and we’ll be sailing our very fine Archer 78, and won’t mention that both locations (of departure and arrival) are heavily militarized and the why’s and what next’s concerning that – mindful as always of SOL Netiquette.

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!
