[QUOTE="Yora, post: 8355672, member: 6670763"] I thought it would be interesting if players try to take overland shortcuts between two arms and up in a completely different place than they thought because the map was wrong. Maybe there's ways to have characters make a navigation check to get to places if there are no reliable markers left behind by other explorers. "Take the west arm where we tied a blue cloth to a tree branch hanging over the water." is easy. "Take the fifth of the major branches on the north bank after having passed the dead tree." might be too vague to be reliable. I did some work trying to find out the cargo capacities of various river sailing ships. I got one very detailed fact sheet for a huge modern dhow, but I think the numbers would not have been that different for older dhows, and I think the capacities are probably similar to a junk of comparable size. Assuming ship weight and cargo capacity for these ships scales proportionally as you make them smaller or bigger, I got these numbers: 40 meter deck length: 480,000 pounds 30 meter deck length: 200,000 pounds 20 meter deck length: 60,000 pounds 15 meter deck length: 25,000 pounds 10 meter deck length: 7,500 pounds 5 meter deck length: 940 pounds That last number happens to be the number you get for a typical 15 foot canoe, so that seems to hold up.
