Might seem like an odd question, but... I was wondering how the prices of charts sold in Shipyards are determined? Is the length of courses or something of the sort?  Cecidrake Senior Officer of The Lost Lot Sage Ocean

By how many leages the chart reveals. 2 league chart (it exists, on midnight anyway) are cheap, the longer 56 league charts are a good bit more, comparatively.  Yamorg, Captain and Navigator Founder, Privately Funded Pirates Association© Midnight Ocean

There's no know mathematical formula for determining the price of a chart. If you happen to figure out, please let everyone know. :)  Barrister  YPPedia Administrator  Looterati

Know i think there is a Mathmatical formula and here it is E=MC2 :p no i think it is [Distance][1617]=price of chart this was a vary brief test i did it only involved 5 charts. but their is somehting to start with.  HIIIIII

I investigated the matter for a while (all on Midnight ocean), here's what I found: 1) the price of straight line charts increase linearly with the number of leagues e.g. CranberryMidsummer: 2 diagonal leagues, 42 poe CranberryEta: 3 diagonal leagues, 63 poe EtaLuthien: 4 diagonal leagues, 84 poe EtaJorvik: 5 diagonal leagues, 106 (ok, tiny anomaly here, but still close enough) 2) Longer charts (by number of leagues) are sometimes cheaper than shorter ones e.g. TurtleAlpha: 7 diagonal leagues, 129 poe TurtleCnossos: 8 diagonal leagues, 120 poe 3) Squiggly charts are always cheaper than straight lines e.g. WrasseGaea: 5 diagonal leagues (2 / and 3 \), 76 poe, much cheaper than the straight line EtaJorvik Then, by looking at the triangle CnossosTurtleAlpha, it occured to me that, even though the chart CnossosTurtle had more leagues than TurtleAlpha, the Euclidian distance (measured with a ruler) from Turtle to Cnossos was actually shorter than the distance from Turtle to Alpha. So I proceeded to get the following measures (measures taken on my computer screen using the median zoom display, so possibly a little imprecise and measures may vary depending on your computer screen and display settings, but still, it's pretty convincing) AlphaByrne: 4 diagonal leagues, 4.7 cm, 84 poe  17.8723404 poe/cm AlphaTurtle: 7 diagonal leagues, 7.1 cm, 129 poe  18.16901 poe/cm CnossosTurtle: 8 diagonal leagues, 6.6 cm, 120 poe  18.181818 poe/cm PapayaByrne: 2 diagonal leagues, 1 horizontal league, 3.7 cm, 67 poe  18.1081081 poe/cm So there you have it, the price of charts is proportional to the Euclidian distance between the nav points of the islands. And for the yet unconvinced, here's the measurements that convinced me I nailed it: CnossosAlpha: 1 diagonal league, 2 horizontal leagues, 4.2 cm, 76 poe WrasseGaea: 5 diagonal leagues, 4.2 cm, 76 poe  Hatchetback Senior Officer of Fifth Fist of th'Misfits

hehe, perhaps... but this kind of thing is wayyyyy more fun than playing poker for an hour (which is about the time it took me to figure this out)  Hatchetback Senior Officer of Fifth Fist of th'Misfits

Wow... what do ye say... simple question and incredible result! Me likes the forums and specially when something new comes out of it :) Cheers to Calorifere for the great investigation :)  Cecidrake Senior Officer of The Lost Lot Sage Ocean

what about route difficulty? does that have any effect at all on chart price. I would have though so?

It doesn't, on Midnight at least. Routes that have the same shape and length, but are believed to be of different difficulty all have the same price (e.g. EtaLuthien, ByrneAlpha and CleoZeta).  Hatchetback Senior Officer of Fifth Fist of th'Misfits
