2008-04-02 17:38:04 - Position changed after finishline?
In the ever going quest to find bugs (and possible ruin my own rating) I need to point out the following (and perhaps get an explanation).

In the Kallavesj race I finished as number 13. Number 11 was my father, BWHA. He was right a head of me the entire time, at least graphically and acording to the leaderboard.

Standing on the finish line looking at my 13 it suddenly became a 11. Perfect :) My dad was now 11 and I also think the one on 12th place was moved around.

Is there some kind of post processing of finish positions? Or penalties :)

Thanks.

Thanks for your great feedback.

The display of client and leaderboard are not updated in real time, I think the thing you ar describing is down to a slight difference in on the server side compared to the output.

But I think Kalle can give you a more complete picture, lets hear what he has to say about this.
I am a ex-admin of SOL who joins in from time to time.

During the course, the boats can actually have slightly different sailing times, up to 1 minute. An active boat is integrated at least every 15 seconds, but if you haven't entered a command in a while, we drop that interval slightly. Note that his has no effect on performance, we just "push" to boat a little more seldom.

Think of it as if each boat had ha transponder, reporting every 30 seconds. You can see all the boat positions on the screen, but the time the report was sent can differ, so the "real" position might be 30 second off.

BUT when you cross the finish line, the exact sailed time is calculated down to the microsecond. This can cause some confusion I agree when the boats are separated by less then 1 minute. Over 1 minute this cannot occur.

Thanks, that makes excellent sense. That could also explain why why I sometimes was ahead of him and sometimes behind.

Africa by Sea - Swakopmund to Maputo 2025


Time again to continue our exploration of Africa by Sea, which now takes us around the tip of the continent at Cape Agulhas and up the coast of South Africa to Mozambique’s marvellous Maputo, where we should find good anchorage in the bend of the Rio Espirito Santo (Umbuluzi) once we’ve cleared the 60m high Maputo - Katembe suspension bridge. It’s 1900nm and we’ll be glad to be sailing our comfortable and sturdy Xp-55, as we will certainly experience more headwinds!

TuziTekwini TIMED Race 2025

Sailonline is delighted to have been invited to partner with the King Shaka Yacht Club (KSYC) of South Africa to bring a virtual version of the Tuzi Tekwini Ocean Raceto our online community.
The Tuzi Tekwini Ocean Race is a near 90 nautical mile race down the east coast of South Africa from the port of Richards Bay to the port of Durban. Achievable in a single day and seen by some as an easy mile-builder, the course is more tactical than some think and should not be underestimated. This iconic race promises to be an unforgettable experience for yachting enthusiasts.
Our online version of the race will be a TIMEDrace so you may RE-REGISTER HEREto try again after finishing a run. You will have 13 days and 11 hours to test your skill and decision making after the race opens.
