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.

Current Races:

Christmas to Christmas Island 2025

Two waypoints, start and finish, and between them 5827 NM of two oceans. Not much time if we want to sit at the Christmas Eve table. You will need to maintain an average speed of over 10 knots, maybe quite possible with this Maxi Trimaran, but prepare your vessel well and choose the best of the many possible routes. Hands up everyone who knew there were TWO Christmas Islands?! OK, maybe you have sailed this Sailonline course before... but it's time to get ready for the 2025 challenge of racing between Christmas Island in the Pacific to Christmas Island in the Indian Ocean! It also marks the conclusion of our prestigious Ocean Race Championship 2025. Please have fun! Fair winds!

Andaman Islands PYOC 2025


The Andaman Islands are an archipelago, made up of 200 islands, in the northeastern Indian Ocean. Together with the Nicobar Islands to their south, the Andamans serve as a maritime boundary between the Bay of Bengal to the west and the Andaman Sea to the east. These waters will be the theater of our next 240nm race in the ARCH 2025 series. Which one you choose depends only on you, i.e. your Elan 410 sport will leave the Andaman Islands on the starboard or port side.

Isla San Lorenzo RTI 2025


SOL’s SRC (Sailonline Race Committee) has taken us to some unusual places in the past, and San Lorenzo Island off Lima’s Callao peninsula is definitely another one. Housing a naval base and a penal institution, no vessel is allowed within 300m of its shores. Also, with no sources of potable water, it is a matter of debate whether it is an island at all, and not just a large rock. So, whatever you do, don’t be tempted to BBQ; you’ll be arrested and go thirsty! We return for the first time since 2018 to race thirteen potentially unlucky miles in J-30s; have fun!!

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!
