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

Red Eye - Key Lime Pie-gatta 2025

Opposite the Bahamas at the tip of the Florida peninsula, we find the Florida Keys, a honky-tonk arpeggio of islands, where another SOL classic, the Key Lime Pie-gatta, so-called after the famous local condensed-milk-based tart speciality, awaits to be navigated once again. We’ll race its “Red Eye” 180nm in very-American Santa Cruz 52s, ignoring such artefacts as bridges, causeways and piers joining the keys one to the other and to the mainland!

Sail Around Turkey 2025


Welcome to the 11th running of one of Sailonline's most iconic races, where our fleet races the length of the Turkish coastline from Hopa (the easternmost harbour on Turkey’s Black Sea coast) to Iskenderun (the easternmost harbour on Turkey’s Mediterranean coast). It’s a 1,372nm race and aboard our classic, 1st decade of the 21st Century, version 2 IMOCA 60, you should be able to get around the course in less than a week. That is if, of course, once you get out of the Black Sea you don’t stop to enjoy the sights or a BBQ or two in the Golden Horn, or on the Marble Islands, now land-locked Troy or Gallipoli or any of the myriad Aegean islands, that you shall have to carefully navigate past.
