I can't figure this out! I have 1907 miles to Cape Horn. NZL 2389 has 2101 miles to Cape Horn. The mileage shows that I am behind them by 1200 miles. It still shows that I have 5300 miles to go. Sorry I only have around 4000 miles to go. What is going on here? Please advise. This kind problems have happend before when crossing the dateline. Please check before the race starts in 18 hours.
Does your DTG value shown in race message 'racing with ## nm to go.' differ from the one shown in the leaderboard ??

We are looking into this

Aaron, both are the same!
This highlights some peculiarities in the way SOL computes your DTG.
In the manual there is an image of rounding a mark, with a line extending from the mark (based on the rhumblines into and out-of the mark). The bearing from your boat to the mark along this line (when your rounding is scored) is also shown on the NOR for that mark.

Now, to compute distance to finish line, the server computes the shortest distance between your boat and this line - computing the point on the line which is closest to your boat at the same time - and then also uses this point to calculate how for to the next waypoint after that. A point further away form the mark thus gets a 'double distance penalty'. It then just adds the rhumbline distance of any remaining legs in the race to get your final DTG value.

So, the server is not computing the exact same thing for the 2 boats, because their point on the 'scoring line' is different, depending what the XTE is.

In fact, if I measure this up now - the South Pole is the closest point on the 'scoring line' for many boats - hence the funky rankings (next leg dist is same for all, but current distance to SP can be less for boats that are more to the W)
Bobbert pointed this out as I was writing the above...

This is the way SOL roundings always work. They'll start to make a bit more sense as we get close to the cape, but will likely go haywire again after we round. They'll be more and more "correct" as we approach the turn into Itajai, and will be perfect at the finish...

76 Trombones. I will agree with your theory that we are using the south pole for distances. Then, I am presently 200 miles closer to the south pole than the leader and I am still listed as 1400 miles behind them? I am sorry but your theory doesn't add up with the rankings.

Don't worry about it! You'll pop out the other side soon.

Each boat uses a different point to calculate DTG, based on what is the shortest path to the next rounding (when it says "rounded", *not* the mark).

Mrnil is currently calculating through the Horn, as that is the closest point on the rounding line from his position. Small distances N/S make a huge difference due to the very shallow angle the Cape Horn mark makes in the GC route.

Bottom line is that all the rankings are consistent (consistently "wrong" according to where we will actually sail) and will sort themselves out by the end.
That was me... And you'll notice that you've made the transistion to #1! I admit that it's not intuitive.
A different perspective on the race:

Isla San Lorenzo RTI 2025


SOL’s SRC (Sailonline Race Committee) has taken us to some unusual places in the past, and San Lorenzo Island off Lima’s Callao peninsula is definitely another one. Housing a naval base and a penal institution, no vessel is allowed within 300m of its shores. Also, with no sources of potable water, it is a matter of debate whether it is an island at all, and not just a large rock. So, whatever you do, don’t be tempted to BBQ; you’ll be arrested and go thirsty! We return for the first time since 2018 to race thirteen potentially unlucky miles in J-30s; have fun!!

Joanne's Test Race Zone

In 1947, Hugh McLean & Sons of Gourock, Scotland built a radical racing yacht for John Illingworth, soon-to-be Commodore of the RORC, to a design by Laurent Giles. With a masthead rig, giving her ‘free’ sail area per the rules of the time, and short overhangs reducing pitching, Myth of Malham went on to win The Fastnet that year and again in 1949, and to compete in numerous Admiral's Cups. In 1958, in honour of the yacht, the Myth of Malham race was conceived - a mini-Fastnet to the first lighthouse on a rock west of Cowes, Eddystone, rather than the second, to be held in non-Fastnet years. IRL this year it has been raced already, but this stops us not from “Red Eye” racing its online 230nm in Fareast 31Rs, leaving how to deal with the Isle of Wight open to your own discretion.

Marstrand to Cowes 2025


We invite you to another race, which will kick off the third quarter of our ARCH series. We'll set off from Marstrand, Sweden, which, along with Skagen, Denmark, marks the line commonly recognised as the border separating the Baltic Sea from the North Sea. The 650nm route will take our Ripitide 50 across the North Sea and the English Channel to Cowes, England. Watch out for the fast ferries crossing the Channel from Calais to Dover 😊.

Welcome to the Shorthanded Sailing Association of New Zealand's 2022 Evolution Sails Northern Triangle series, which, unfortunately, to comply with latest NZ government COVID restrictions, has been reduced to a duo, commencing with this short prologue of approximately 35nm on the waters of Auckland's Hauraki Gulf. As so often with SSANZ events in the past, online we will be racing the event in ever-young Young 88 one-designs. Have fun!
Please note the displayed course is provisional; the actual course will be set after the IRL course is announced at the skipper's briefing 48 hours before the start, and no later than 24 hours before the start.

Aland Sea TIMED Race
Norrtalje Segelsallskap, 70km NE of Stockholm was founded in 1920, and time was when the society’s season opened with a challenging offshore race from the club line off Flaten island at the mouth of the long and narrow Norrtaljeviken, out onto a triangular course around the Aland Sea, to finish at Simpnas slightly to the north on Bjorko island - some 78nm in total. A fine race that SOL, being from these parts, ran annually up until 2013. Last run in autumn 2018, we return here to race the course again in the form a TIMED RUN in spanking new Club Swan 50s.
