I once experienced a moored ship whose satellite Internet was extremely unreliable. It worked for 2 seconds and then it stopped working for two seconds, over and over. Only time it worked reliably was when there were no wind at all. After checking satellite images and corresponding to antennas pointing angle and ships position we eventually figured out that the antenna was pointing directly towards a wind mill. So when the rotor was turning it was intermittently blocking the signal between the satellite and the antenna. Luckily they were able to move the ship 50 meters forward and magically the Internet started working again.
