2008-03-29 22:04:19 - DTG and leaderboard
From Jakob I understood the distance (DTG) calculation as the following; The distance no next rounding is calculated as the shortest distance from where the boat is to the line (bisector) straight out from the WP. From that point the distance straight to the next actual WP (not to a point on the line from that WP) is added and then the distance from WP to WP to goal. This means that DTG can actually increase at a rounding because as for Cabo San Lucas in the "route for gold", when passing the Cabo San Lucas rounding line, the next rounding is moved from the Big Sur WP out in the ocean to the closest point on the line. And then the DTG increases because the distance from the rounding line point to goal has increased.

The "correct" way would probably be to keep calculating to the closest points on the rounding lines all the way to goal but that would consume too much computer power according to Jakob.

Rapallo to Nador 2026


Welcome to Liguria’s Rapallo, there where Zarathustra spoke - at length - to Nietzsche, for our first race of nine to celebrate all things Mediterranean - fickle winds, history and olive oil. A number of our races in this new Magical Mediterranean series will be partnership with famous real-life races, but this first race is pure fiction - 780nm in refurbed IMOCA 60s, past or through the Balearic Isles and on into the Alboran Sea, to a finish off Nador on the Maroc Mediterranean coast.

Red Eye - Melville Island PYOC 2026

Melville Island is the largest of the Tivi group opposite the port of Darwin in the Timor Sea. Tropically forested and thinly populated, not a lot goes on there, but let’s race around it anyway, lar- or starboard round, it’s a little more than 120nm, so, no matter where you are navigating from on the planet, you will be hard-pressed to complete the course aboard your J-80 in daylight hours!

Cross the Convergence 2026 - Guam to Ouvéa


The third race of our series of ocean voyages across the World’s convergence zones takes us southeastward now down the Pacific, from Guam’s Apra Harbour at 13.5 degrees North, back across the Equator to the glorious New Caledonian resort island of Ouvéa, on the edge of the Tropic of Capricorn at 20.5 degrees South. It’s 2400nm, and there’s more than a few other islands in the way, so mind where you go in your Ocean 50s. Race #1981
