2010-07-02 15:23:37 - Great Circle Route
Forgive me if this subject is covered elsewhere, but does the game take into account that the shortest route over longer distances is a Great Circle? Or do the game maps not account for this?

If you notice on the Game display screen to the left, there are five icons for you to use, The bottom most yellow dividers will allow you to plot the shortest distance GC by clicking where you want to measure. It will look curved on the Mercator projection.

However when steering your boat you either choose a Constant compass heading or Constant angle to the wind, so following a GC route requires an active skipper on board.

Thanks for your help. Perhaps I should have worded my Q differently: Is the distance to go shown by the game calculated along the great circle, or does it assume a flat ocean? I infer from your answer however that it must be the great circle distance. Thanks again.

The Rhumb Line shown in the Game and the DTG are less reliable as to accuracy relative to your best route & actual distance needed to cover it. That takes some experience to gauge and should be considered a rough approximation but as the race evolves it does improve.

I would only Trust the DTG if you are the sort of person who waits for your fuel gauge to get to the 'E' before you look for a gas station.

Doesn't "E" mean "enough"?

Oh? I thought it meant something else! Like in "Oh f... - forgot to fill!"

BTW, I have tried uploading an avatar, how long does it take to appear by my posts?

The Avatar should appear as soon as you choose it, if done properly.

So try again.

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!

Camel or Balloon - Khartoum to N'Djamena


As there is a lull in the calendar, your PRO has decided to risk an experiment – a balloon race over land, using a workaround to eliminate the recognition of water/land transitions. If it fails, the server may crash, and we abandon PDQ, hopefully after leg 7 of the ABS race to Suez has been decided, and before the start of the 1st OCC of Q4. Camel or Balloon – c 1000 nm from a field on the north bank of the Blue Nile at Khartoum to a field on the north bank of the Chari River at N'Djamena!
