    I pledge to sail the prolog by the SOTP. It was much more fun anyway, when this was the norm.

    RIP Aaron.

    This poem, which is written into the Memorial at Cape Horn, which you rounded at least virtually many times, is for you and your family.

    I, the albatross that awaits for you at the end of the world...

    I, the forgotten soul of the sailors lost that crossed Cape Horn from all the seas of the world.

    But die they did not
    in the fierce waves,
    for today towards eternity
    in my wings they soar
    in the last crevice
    of the Antarctic winds

    Sara Vial
    Dec - 1992

    The divider/measure tool works a bit funky as it lays down a route but when clicking on the tool again the route disappears. This is not conducive to planning ones strategy easily. It would be better if the route you just placed down would stay there until you double clicked the tool or single clicked to add to the existing route set down or being able to set a second route to compare with the first.


    I support this feature request very much.

    If the courses are all "COMPASS" courses, then the predictor is very accurate and the margin of error is indeed small.

    I doubt that. Of course, you know your boat will be somewhere on that line, but the speed of the boat within the next 6 hours is uncertain and therefore the location on that line. Using TWA the speed might be more predictable since then it only depends on the wind speed and not the direction, but of course you are not necessarily on that line but the difference on average is similar to when sailing via CC.

    Before developing any VMC, I would prefer development of the predicted course indicator to include any DELAYED COMMANDS.
    Oh yes, I second that. I also would wish for the course predictor to extend to e.g. 12 hrs rather than six. But I would give the inclusion of delayed commands higher priority. Then an extension of the course predictor and last but not least I would rather have VMC than VMG.

    That's for sure. Looking at the weather is essential. And that's why SOL would not be mechanical with VMC as a previous poster claimed. But showing the VMC would help to judge losses and gains on detours due to weather.

    VMG to waypoint
    Board » Technical Support
    I don't quite agree. Of course one need a bearing. The bearing is quite easy to get. To the next way point. The argument with the finish line is rather weak. If you are far away, the exact point on the line does not matter. Just default to the midpoint as it is on the red line which connects all the way points. Then the VMG get useful. Currently, I fing the VMG not useful at all. When is the course really upwind? And then the VMG upwind is easily estimated. Just add horizontal lines to the polar and you have it.

    Thanks for the quick answer. And sorry that I missed the answer earlier.

    May I turn that into a feature request, then. I see that VMG to way points is of limited usability, if you have to navigate around weather systems, but it would still be nice to have and very useful in shorter in-shore races.

    wrong VMG
    Board » Technical Support
    I think that has been mentioned before: the VMG is still showing wrong. At least for me (firefox 3.0.8 on linux). I think it is wrong since I rounded the mark at Fernando de Noronha. Before that I had the impression it was show the VMG directly to Boston (also not quite appropriate), but now the VMG is calculated as if the next mark would be directly upwind rather than towards Boston. See the attached screen shot. I am sailing with a TWA of 90° and the VMG is 0.00knts though I am pointing roughly to Boston (and the boat speed is not 0knts).

Raja Muda Selangor 2025 - Port Klang to Pangkor

Sailonline is delighted to be able to offer online sailors an opportunity to once again compete in all three of the offshore races of the Raja Muda Selangor International race week, organised by the Royal Selangor Yacht Club in association with the RORC, and commencing with a 75nm trip from Port Klang to Pangkor. This year we will be racing this race, and the other two, which together will count towards our Sailonline Raja Muda Series (RMS), in J-109s.

Africa by Sea 2025 - Suez to Port Said


When Napoleon (briefly) occupied Egypt at the turn to the 19th C, he ordered his expedition’s Directeur des Ponts et Chaussées, Jacques-Marie Le Père, to evaluate the ancient, derelict, infilled course of a Ptolemaic canal connecting the Red Sea to the Nile via the Great Bitter Lake, versus a new canal to the Mediterranean directly. Neither were considered feasible – locks to climb a pauvre-surveyed 10m sea-level difference, or continuous dredging of the Nile, would both be equally financially prohibitive. Fifty years passed before the unlikeliness of Le Père’s survey finding was challenged and a French Compagnie Universelle du Canal Maritime de Suez obtained a 99-year concession from the Khedive of Egypt, Said Pasha, to construct and operate a canal from the Red Sea to the Mediterranean, much against the will of the Ottoman Sultan, Abdulmecid I (the Pasha’s nominal overlord), and the wishes of the (Irish) British prime minister, Lord Palmerston. The year was 1859, the very number of this race (planning, dear boy, planning!), which, despite the canal’s double-super-tanker gauge and lack of locks, is strictly prohibited IRL. 85nm in Fareast 28Rs to complete your circumnavigation of Africa!

Fernando de Noronha to Faroe 2025

The RWW Series concludes with a spectacular journey from Fernando de Noronha to the Faroe Islands, a legendary destination in the wild North Atlantic. Panning 4,100 nautical miles, this leg will be a true test of endurance, strategy, and sheer determination. Also the penultimate leg of the 2025 Ocean Championship, it’s your chance to prove your mettle against the sea, the wind, and yourself. We’ll be racing aboard the Ragamuffin 100, a vessel built for speed and challenge — demanding planning, precision and grit from every sailor on deck. Do you have what it takes to master the Northern Atlantic?.

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!
