Great guys :-) but what about the port for brainaids NMEA proxy? It's automatically set to 5010, but I'm shure I cant use the same port if I have 2 or 3 races to run simultaniously, or what?

Viva all.

Installed the new qT version (5.3.9) and the only big difference I’ve noticed was the Polar display bug that was solved.

Still remaining the old problems of:

1 - Over decimating waypoints during the “Simplifying” process;
2 - Increased ETA after the “Simplifying” process;
3 - Idem, after “Optimizing”;
4 - Tacks/gybes times under the specified times in the “Boat settings” menu.

There’s no other way to say it.
Again frustrating, because it takes almost the same time as the routing calculation to correct all the bad “curves” generated after the “Simpl./Opt” processes.

I'm trying to understand what 'simplifying' means. If it's deleting poi's that are within a certain margin not leading to a different heading then indicated by the surrounding poi's then this simplifying would just cause less poi's. This is not the same as a decreased ETA. If you then optimize these simplified poi's series I can imagine that this optimization of 'errors' brought in by the simplification again can do unexpected things with ETA.

Why would you try to 'simplify' JB.
Could you not first 'optimize' and then 'simplify' the exported csv by yourself?
deleting same TWA's and or same headings?

I'm trying to get a better understanding of what a router does. Hence these questions.

Simplifying has 2 modes: optimum and maximum. Optimum keeps more points and is slower to run. Maximum will try hard to remove a maximum number of points. Maximum mode might even increase slightly ETA.

If "optimum" looses time (ETA) then it's a bug. Please provide necessary information to fix it since I didn't succeed to reproduce it.

Also explain and provide examples for the "time to tack" issue your are mentioning.

Beware a new qtVlm version is due in the coming days. To avoid frustration again better provide some more info on existing problems, or they will stay as they are once more ;)

Regata dell’Accademia Navale 2025

Welcome to Sailonline’s first partnership with the City of Livorno, in cooperation with the local yacht clubs and the Italian Navy, to offer you the online opportunity to race the Regata dell’Accademia Navale. 630nm in length, starting and finishing in Livorno, the race takes you the length and breadth of the Tyrrhenian Sea via Porto Cervo and Capri. Online, you will be sailing a Class 40, which should keep you well in with the top of the real-life fleet which we will be tracking on screen!

Transat à Deux 2025

Above you see a single-handed sailor semi-foiling his Beneteau Figaro III to the horizon. It is in fact Ireland’s Sailor of the Year and the overall winner of last year’s Solitaire du Figaro, Tom Dolan. Somehow, we got our hands on a polar for the Class, and rather than trying to surreptitiously track Tom and his mates in the 2025 edition of the Solitaire, sailing rather-short, single-handed legs across the Celtic Sea and Biscay, we thought we’d see how our virtual craft would fare on the Class’s double-handed 3900nm Trans-Atlantic, from somewhere in Brittanny to somewhere in the Caribbean via somewhere in the Canaries. Allez, mes braves!

Sinbad by Balloon 2025 - Toamasina to Baia de l'Oiseau


You may recall that when last we visited Madagascar in the company of Sinbad, the Sultan commanded our intrepid inspirator to seek out fabled islands where in Summer the sun barely set. We did and we returned but the Sultan wasn’t happy with Sinbad’s report, so here we go again, now by SOL Balloon instead of sailing vessel. Expect to be in the air for at least 2100nm and depending on how the wind brings us, anything between two weeks and two months before we shall descend at the Sultan’s given coordinates!

Melbourne Osaka Cup Double-Handed Yacht Race 2025

Welcome once again to what these days is Sailonline’s almost annual virtual Melbourne to Osaka Yacht Race. In real life, this double-handed 5500 nm race between these two sister cities, one deep in the southern hemisphere, the other high in the northern hemisphere, is run every four to five years, and this year is such a year. So, this year’s online version is in sync with the Melbourne Osaka Cup 2025 organised by the Ocean Racing Club of Victoria (ORCV), and the Sandringham (SYC) and Osaka Hokko (OHYC) yacht clubs. We’ll be racing the well-known First 40, a popular size of boat which should be a good match for many of the boats entered in the real race. With the doldrums unavoidably lying across our course, you can expect to be at virtual sea for at least a month!
