There are at least two companies making kites to pull ships:

* skysails
* kiteship

With a two rope kite you can have it pull you to the left or right of downwind by maybe 75 degrees. So you can use it to pull you in the direction you want if you are mostly moving in the direction of the wind as you might with a migration. A computer can control the kite. By adjusting where it is in the sky and if it is moving back and forth the computer can control how much it pulls and what the average direction of pull is.

A fleet of seasteads with kites and sea anchors would need the computers to be able to communicate so the whole fleet could move in formation without bumping into each other.

A sea anchor can slow down a seastead.
