Just guessing here, but the geographical advantage probably requires a fiber link, which seems prohibitive in open ocean. Putting your ship in the right place probably doesn't improve your latency if you have to bounce signals off of satellites.

It doesn't help if you need to use satellites, but you cloud use microwave. Microwave is line of sight, which would usually limit you to 40miles, but if you were to have a big blimp tethered to a big barge, then you can increase the line-of-sight distance.
