How far a horse travels in one day

[kortleggur]

You estimate it at 25%. How about saying more about why your figure is so seemingly generous.

Well, my system only has 3 penalty groups for travel -25%, -50% and -75%, but these penalties will add up on top of each other, As the adding of penalties adds complexity therefore the system has to be simple in the beginning. As a GM if I choose to have settlement nearby then I will reduce the penalty down to 50% because of all the paths. But then there is the addition of Hills or Mountains as lava is often on the mountains. that will give 93,75% or 95% penalty (if I keep it in the 5% breakages)

So AA lava on a mountain -93,75%
and AA lava on a mountain in a storm -98,44%

Great. The last two postings make clear why the 25% figure and, also, that it probably is a pretty good figure.

Next question: One assumes that the jötnar with their added weight might crush those fussy sharp spots as they cross them, so would you give a jötunn a bonus against the penalty?

(You're already excused if you don't take that question too seriously.)

Oh finally! The answers to my questions! My friend and I struggled with this problem years ago, while writing a story about Robin Hood. Now These will be more useful for my book!!! Thanks!!!

This whole thread has now saved me weeks of mental torture as I was about to start researching this very subject.

Oh good, then you can turn your attention to "How far a clipper ship travels in one day."

That's a problem again. Are you talking about a clipper with sails or are you taking a more historical perspective and are referring to a PanAm Clipper? I can assure you, the differences in travel time will be HUGE! Let us start calculating. Kortleggur, do we have to build in any modifiers (for one clipper, the other or both) if the local eldfjall happens to be blowing its top?

Forward, onward and upward!

Wikipedia states it could be 30 km/h in the best possible conditions. He can maintain that speed as long as he remains in the trade-winds. Apparently the record is 41 km/h but only for a short moment. Otherwise it depends on the winds. Apparently, the average speed of the Trade-winds is about 25-30 kmph. Navigation in the Doldrums and the Horses latitudes is usually very slow since the winds are weak.

Anyone knows the speed of the Westerlies and the Polar Easterlies ?

here is a link for trade winds

http://www.britannica.com/EBchecked/...703/trade-wind

Its average speed is about 5 to 6 metres per second (11 to 13 miles per hour)
but can increase to speeds of 13 metres per second (30 miles per hour) or more.

Also this map is a gem on where the trade winds and currents combined are useful for shipping

and for the horse latitudes these are fine.

It is also a worthy note for any game design that we also have seasons that change the layout of the routs. and several anomalies like el-nino, So if this was a game mechanism then I would roll 1d6 every year and on 6 there is el-nino, also if 1 is rolled then roll again but some variant effect are double.

have fun...

Here is also a good resource on sailing http://nabataea.net/sailing.html with a rout table where we can see what direction the wind is at what months.

from that page, for interest of our travel time theme is this passage:

The Monsoons
From an Arab perspective there are three basic monsoon winds. First of all, from April to June, the Kaws wind blows southwest. Later the Dammani SW monsoon blows from August to the middle of October. At this time, the monsoon changes direction, and the Azyab monsoon blows in a NE direction.

Most ships crossing the Indian Ocean planned to leave the east coast of Arabia during the second half of November and the first half of December. Ships leaving the Red Sea would start out the middle of October, so that they could catch the Ayab monsoon across the Indian Ocean, directly to the Malabar cost, reaching Kulam Mali during December. If they were moving on to China they would have to wait for the cyclones of the Azyab to die down in the Bay of Bengal before journeying on in January, crossing from Mulam Mali round the south of India to Kalah Bar in the Malay Peninsula. Arab ships usually did not venture farther than this, as Chinese junks brought their trade goods to the Malay Peninsula, and may to the island of Ceylon. (Sri Lanka) Once the Kaws winds started to blow, the Arab sailors would start for home, laden with their goods.

The chart below illustrates some of the sailing seasons that existed between India, Arabia and Africa. As local conditions such as land breezes would vary along the Arabian coast, the seasons were more complicated for the specific ports shown in the chart. Nevertheless the chart provides a broad outline.

From the table you will notice that the south-west monsoon strikes earlier further south, and lasts longer. As it moves northwards its duration shortens. Hence the Malabar coast of India is a dangerous place to be as early as May and remains so through September. This means that the sailing season in Malabar, India was only seven to eight months long. This affected the Indian vessels more than the Arab ones, for while the Indians must be all the way home before May, Arab vessels must only be clear of the Malabari waters before then. This allowed the Arabs more time to travel since they had a much longer sailing season when traveling from Arabia to India and back. This would help explain why the Arabs, who came from a land without abundant timber, dominated Indian Ocean trade routes for long periods.

Ágætur! Although in Óðinn's time, I think they left the u out.

I'm going to stick this thread. It's too much of a gem to lose over time.
