OK,I'm a dummy. I can't figure out how to see the various polars before picking a boat! Not much time left. Can someone point me the right direction? Thanks.

If I understand the handicapping correctly, 'uprising' is performing best in these low winds. I do like max VMG at 180 to the wind!!!!
If it breaks, it's not strong enough--if it doesn't, it's too heavy.

Interesting boat, uprising, actually sails faster downwind at TWS 8kn than at TWS 11 kn. How they do that?

Here is my suggestion about the polar for "uprising", as shown in both the original presentation and in the SOL screen. This was requested by "WhyNot".
It does suggest an error may have been made in deriving the polars---and that the superior performance of 'uprising' may actually be due to a calculation error????

That makes sence! I noted the "strange behaviour approaching finish line. Saw a couple of uprisings on "long final" sailaing approx TWA 180. Thought maybe I could catch them - but No Way. Suddenly they went into OverDrive:) Saw this in Navmonpc (and I know Nnavmonpc may not be accurate) Also uprisings well behind caught up. I think the boats are performing according to the weird Polar.

Red Eye - Frisian Isles Trophy 2025

For our final “Red Eye” race, we invite you to cross the Noord Zee to the Wadden Zee, where a 160nm course around a few sandy islands raced on SOL only once before in 2010 awaits you. We don’t have a replica of Erskine Childers’ Dulcibella in our boathouse, and in any case if we took her out, we might well contract more than one “Red Eye”, so instead we’ll race our very own riddle of the sands in Farr 400s!

Mistli's Birthday BBQ Race 2025


Welcome to one of Sailonline's great traditions - the ofttimes slightly untimely celebration of SOLer Mistli's birthday on November 1, by way of a tricky race through the Stockholm Archipelago. To match the day that’s in it, this year correctly, we are providing you with a fleet of sleek 11 metre 1-designs (get it?) to slice through these (at least) 61.5nm of SLI-infested waters, and give you a fair chance that there will still be some beer left by the time you moor up by the jetty at Trosa!

Sinbad by Balloon 2025 - Carnarvon to Dondra


From here, our home in Bharatavarṣa is now north west of us – said Sinbad to his fellow balloonists. Perhaps we can ride the wind first further north, and then catch the winds that every year bring the rain, perhaps not. It’s 2600nm and we could be aloft awhile, so, Master el-Quarters, victuals only, no sandbags, provisioning the giant hamper. It will be not a picnic!
