If a marker says Pass NE you have to at least hit a certain latitude to the north and a certain lontitude to the east of it. Apparently, you didn't touch upon the lontitude. Do not turn back until the marker says "Rounded" to indicate you have indeed rounded it.

The marker in the web client will show when the marker is rounded.

See attached jpeg.

I did not know that Philip, thank you for the info. when I look at the figures my turning point is 118.524 E which is almost 0.5 m east of the mark.. do you know why system does not read it as it is crossed?

I don't really know if this is how it really works and I am not sure if can explain it properly, but in my mind I approach it like this: in this case, the mark is a 90° angle from a compass course of rougly 270° going to 180°. I think the trigger for passing the mark is an imaginary line at roughly 45°, so the further to the north you are, the further east you have to go to trigger it.

Like I said, I don't know if that is true, but that's the way I think of it. In the image I posted earlier I was on dc, so I made sure I had some margin.

Good luck,
Philip

Schakel is basically right.

Let's work with an example. You are about to pass the waypoint above in the attached picture.

The angle between that waypoint and the previous one (below left) is 240°. The angle between that waypoint and the next one (below right) is 170°.

To pass the current waypoint, you have to cross the imaginary line (shown in red) that bisects these two angles.

In our example, we could calculate the bisector as follows:

Total angle between the two routes:
(360°-240°)+(170°-0°) = 290°

Bisector:
240° + 290°/2 - 360° = 240° + 145° - 360° = 25° or
170° - 290°/2 = 170° - 145° = 25°

Francois

Mad Max by Balloon 2026 - Across the Outback


Mad Max Rockatansky doesn’t get to go in a balloon in any of the Legends of the Wasteland, and the Wasteland is not necessarily the Outback of Australia, but Mel Gibson and film director George Miller indubitably are… of Australia, and ballooning as reconnaissance is a main feature of the Mad Max spin-off video game, so here goes: 1500nm in a balloon from somewhere on the edge of the Outback, Goondiwindi, to cross a finish line at Fitzroy Crossing, somewhere on the edge of the Outback!

Roma Giraglia Regata 2026

Our eighth race of nine to celebrate all things Mediterranean - fickle winds, history and olive oil – is another buddy-up; this one with the Circolo Nautico Riva di Traiano . Founded in 1984, as the new Traiano yacht Harbour neared completion, the Circola since then has developed into one of the major yachting competition centres in Italy, and next to the 450nm Roma per Tutti (which SOL buddied earlier in the year), the Roma Giraglia Regata is its other headline offshore event. First raced in 2005, the 210nm course takes competitors from Traiano to a rock on the inside of the Ile de la Giraglia off the northern tip of Corsica and back to the Italian mainland for a finish in the bay of Santo Stefano. We’re racing this one in our Class 40!

Cross the Convergence 2026 - Masirah to Chagos


Having crossed, re-crossed and re-re-crossed the Convergence Zones of the Pacific and the Atlantic, we now face our second crossing of the Convergence Zone of the World’s third great equator-spanning sea, the Indian Ocean, taking us from the channel between Masirah Island and the Oman mainland to the Chagos Archipelago. It’s 1900nm and we’ll be sailing our very fine Archer 78, and won’t mention that both locations (of departure and arrival) are heavily militarized and the why’s and what next’s concerning that – mindful as always of SOL Netiquette.
