Is it possible to hide oceaniac settlements from sattelites?

Doing some worldbuilding, and my setting is roughly modern equivelant (some countries have predominantly non-humans), and one of my nations is mostly seafaring. Using giant ships based on the Freedom Ship idea (one mile long nuclear powered cruise ship), and vaguely based on the quarians from mass effect, I was wondering if there was a way to disrupt sattelite imaging for the ships, or if I go with stationary ocean settlements (like giant oil rigs, but for permanent living). The idea would be to blend the images around the boat/rig together to make it look like there's nothing there.
