Hi
.. first of all:
great site ! So a big "Hurray" for the brains+fingers behind the game: Tack sa mycket.

Finally decided to read the manual and kind of got a simple question, yet tricky to express:

"In front of your boat is a "predictor" showing where your boat would be in 6 hours if the conditions where frozen as they are right now"

Suppose wind would be frozen and the weather shows e.g. 10knts at t=0-2h and 20knts at t=2-6h along the cours.

Is the length of the "predictor" calculated on( v=10 for 6h) or (v=10 for 2h + v=20 for 4h) ?

Guess it is option (1) but just wanted to be sure.
Hi there

Yes your first explanation is the right one. The predictor doesn't take in account any forecast change.
Its just your current compass heading with the time in hours with current wind speed.

Im bussy with a new manual and will try too put a better explanation of this feature in place.

I am a ex-admin of SOL who joins in from time to time.
Yeah - it is somewhat tricky to get this one a hundred percent clear.
Should I get an "inspiration" (lol) about it, I'll let you know.
We are about to introduce some news on this subject very soon :-) Hold on and wait a few days. Come back here if things still are unclear.

Guess you missunderstood my answer, Jakob - I was refering to "how to put it in a new manual"
sorry - wasn't too clear myself.
language is full of obstacles. *stumble*

YEAH IT IS!!!!

WOW... Thats a great feature Jakob & Kalle et al...
I think it should make for some closer racing!

Sozi: It is already quite clear about the indicator in my opinion, and also, as the marks for each hour (and now sub marks) are equally spaced, this also implies constant speed, hence constant TWS.

This already fantastic site just keeps getting better...

Now, could you just include wind strength and tidal effects and the possibility to let it know the helmsman is drunk and might not sail a straight course! LOL ;-)

I help develop the client interface for the best online ocean racing sim there is... __/)/)_/)__
Great work it looks really cool and a great addition with the quarter hour submarks.

Just one question though, atleast my line isn't straight, it actually feels like it has a slight S shape to it, very subtile but still. Is this just my eyes playing a trick on me or if not what does it predict? great circle?

Having looked at it some more, it seems that when you set the boart to sail under twa the predictor isn't straight as it used to be, is it taking into account weather forecast or something?

Thanks!

@Aaron - The question was refering to the old predictor..

@Pergite: I'm sure it does!!! weather, windshift ect..

Those guys are somewhat crazy :)

And this is not simply cool: it is amazing!
Almost too good!

Wonderful work Jakob et al!

It is simply that the arrows behind are describing a curve - a common optical illusion. Love the work you guys keep doing and the quality that we are offered.

Transat à Deux 2025

Above you see a single-handed sailor semi-foiling his Beneteau Figaro III to the horizon. It is in fact Ireland’s Sailor of the Year and the overall winner of last year’s Solitaire du Figaro, Tom Dolan. Somehow, we got our hands on a polar for the Class, and rather than trying to surreptitiously track Tom and his mates in the 2025 edition of the Solitaire, sailing rather-short, single-handed legs across the Celtic Sea and Biscay, we thought we’d see how our virtual craft would fare on the Class’s double-handed 3900nm Trans-Atlantic, from somewhere in Brittanny to somewhere in the Caribbean via somewhere in the Canaries. Allez, mes braves!

Sinbad by Balloon 2025 - Toamasina to Baia de l'Oiseau


You may recall that when last we visited Madagascar in the company of Sinbad, the Sultan commanded our intrepid inspirator to seek out fabled islands where in Summer the sun barely set. We did and we returned but the Sultan wasn’t happy with Sinbad’s report, so here we go again, now by SOL Balloon instead of sailing vessel. Expect to be in the air for at least 2100nm and depending on how the wind brings us, anything between two weeks and two months before we shall descend at the Sultan’s given coordinates!
