Re: Fast X Boat
In reply to #3065 Fast X-Boat by Pauli
hi,
I designed this ship mostly to see how effectively such a thing could
be done. It would be a very popular thing to build and it probably
wouldn't be very cost effective due to the number of ships required.

Oops, I made a slight error here. However, it isn't that bad. The mean is
better than 10.5.
Not quite that easy....the mean of a product isn't the product
of the means. The result you want is:
for 1d6, average is 3.5
for 2d6, average is 7
for 3d6, average is 10.5
for 4d6, average is 14
for 5d6, average is 17.5
for 6d6, average is 21
Summing the averages and dividing by 6 gives: 12.25 hexes average mis-jump
distance. This is possible because each of the above is equally likely.

Most probably you need 2 jumps, you have an even chance (50%) of getting
somewhere in 1 jump and a 127 in 128 (= 99.2%) of getting somewhere in 2 jumps.
If you put a jump-2 drive in the ship you would have a really good chance of
getting somewhere in 2 jumps.
As seen above, this method is slightly better than two controlled jump-6s
(.25 hexes on average). The variance is much larger and since this method
of communication requires multiple ships to be launched, you have a pretty
good chance of sending the stuff further. You also have a nice chance of
sending is less far as well.

Maybe I'd better include a second engine in the next redesign.
