    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

    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.

    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).


Next Race: 00d 00h 00m

Current Races:

Galveston to Galway 2022
For the second time, we will be able to test our navigational skills in this massive ocean race across the Gulf of Mexico and the Atlantic Ocean! You can navigate the 4980 NM to Galway, Ireland in any direction, of course within the designated race boundary area. Your only task is to reach the finish line in the best place, preferably at the highest podium. Prepare your C2R 74 well for the race and take advantage of all its opportunities. Good luck!

Sines to Bermuda 2022
Another race with the finish line in Bermuda. This time we will start from Sines in Portugal. There is 3213nm ahead of us across the Atlantic Ocean. Previously, this race was one of the stages of the Rendez-Vous 2017 Tall Ships Regatta. This time we will use this route in the race played as part of the SOL All Round Championships and we will use our Orange 125 fast catamarans to cover it. We invite you to participate.

Geraldton to Cape Town 2022
A race in the Southern Indian Ocean is always entertaining, especially in a Riptide 50. Traditionally the course would be West to East, to take advantage of the prevailing winds, but this time the SRC is challenging us to an E-W course, from Geraldton in Western Australia to Cape Town in South Africa. A brief 4800nm!
