My present distance to the goal is 12211,1
The leader's distance to the goal is 11811,6, which means I am 399,5 behind
The measured distance between the two of us, using the measuring tool, is 278,3 nautical miles, which can't be true, especially as I am more beside than behind the leader. How is this possible?

It might be correct anyway :-) We measure distance to goal by measure shortest distance to next rounding first and then the distance from that point to goal. That usually works pretty well but in some cases are not 100% intuitive. Have faith :-)

But this time Jakob some more explanation is needed I think.
This morning, tuesdag 17/2 at 5.40 UTC, I got up and had 12040 nm to finish. The present leader had about 11580 nm to finish, and he/she was only some 20 nm to starboard. This boat was not even sideways in front but sideways behind me.
That needs some more explanation I believe.

First I cal the dist to rounding, then dist from that to finish. When we are soooo darn far from rounding and the pole is involved, the point of rounding is moving around. Take a globe and play around with it and you will see what I mean. :-) The calcs are ok, but the concept of dtg is ambigous at the moment. Be cool and things will start to make sense as we come closer to cape.

Tall Ships Races 2025 - Le Havre to Dunkirk

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.
