2009-01-11 08:34:43 - 1st Marker on the prediction line
There are 7 marks on the prediction line, 6 of them are at 1 hour prediction points, what is the first point? This point is close to the boat. Is this a point at which when it is past a mark or headland you can safely send a command without rounding too early or hitting the headland.
Thanks

It's a little bug that will be fixed very soon! The first dot is approx 1 minute from the boat.

Is there any way of knowing when to execute a turn around a headland or mark without cutting short or hitting the land?
Maybe the extra mark could be kept and placed at the point at which the command will be executed if entered immediately after the last update. In other words if this mark is beyond the mark/headland you can safely enter your turn command.

First, we are working on implementing a "smart" predictor that will actually take the currect forecast in account. However, since there is no way for us to tell what data a NEW will have, we can never make anything more that a "prediction", so we can never make a guarantee that a boat will arrive at a certain point at a certain time.

Woa, things got a little complicated...please ask if you need a clarification.

What you are talking about is great it is a lot better than having nothing. What I am talking about is is more in the real time scenario. ....coming up to the mark .....ready steady ....hit send... aaah sheeees .....too early!@#&%!
Now if that mark I talked about is placed (like the 1hr ones)ahead of your boat at one interval of update increment, it would be relatively safe to send a command if it has reached the target

I think when approaching the mark it is always the compromise between being safe and cutting it tight. We also have an update to the server side planned (ETA not known) that will increase the update times, that will also help.

Mistli's Birthday BBQ Race 2025


Welcome to one of Sailonline's great traditions - the ofttimes slightly untimely celebration of SOLer Mistli's birthday on November 1, by way of a tricky race through the Stockholm Archipelago. To match the day that’s in it, this year correctly, we are providing you with a fleet of sleek 11 metre 1-designs (get it?) to slice through these (at least) 61.5nm of SLI-infested waters, and give you a fair chance that there will still be some beer left by the time you moor up by the jetty at Trosa!

Sinbad by Balloon 2025 - Carnarvon to Dondra


From here, our home in Bharatavarṣa is now north west of us – said Sinbad to his fellow balloonists. Perhaps we can ride the wind first further north, and then catch the winds that every year bring the rain, perhaps not. It’s 2600nm and we could be aloft awhile, so, Master el-Quarters, victuals only, no sandbags, provisioning the giant hamper. It will be not a picnic!
