Dear Sirs,
How come boats can sail right through the land at 107.75 and 3.00 at one end and 107.28 and 2.99 at the other end.

I altered course to avoid what looks like land,i.e. an island, as I had seen it to late.

Others and lots of them just kept going.
Carnaby Street and Juju_GB are two boats that did that.

Is there an explanation and is okay to do?
Cheers,

As I understand it, it has to do with the interval between updates. Apparently, the boats sort of jump ahead each update. As a result, if the circumstances are just right boats may appear to jump over narrow bits of land.

Philip
Yes Schakel is correct there.

Boats jump ahead between updates and each time a boat has jumped a land hit check is done. If you are lucky and clear the land in the mean time, real small stretches of land may be cleared without stopping. You take a risk by doing this, if you do jump at land your boat will stop.

This is done to reduce server loads and most of the time the boats that are jumping are not very active in the race.

I hope this helps, Jeroen

Jeroen, is server load or boat activity also the reason that some boats are shown as dots?
If im correct we did that to reduce the clutter of the number of boats we are running now. And might reduce a bit of overhead too.

Thessaloniki to Port Said 2026

Welcome back to the Eastern Mediterranean for the fifth race of our Magical Mediterranean Series.

TuziTekwini TIMED Race 2026

Sailonline is delighted to have been invited again to partner with the King Shaka Yacht Club (KSYC) of South Africa to bring a virtual version of the Tuzi Tekwini Ocean Raceto our online community.
The Tuzi Tekwini Ocean Race is a near 90 nautical mile race down the east coast of South Africa from the port of Richards Bay to the port of Durban. Achievable in a single day and seen by some as an easy mile-builder, the course is more tactical than some think and should not be underestimated. This iconic race promises to be an unforgettable experience for yachting enthusiasts.
Our online version of the race will be a TIMEDrace so you may RE-REGISTER HEREto try again after finishing a run. You will have two weeks to test your skill and decision making after the race opens.
