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 sea anchor can slow down a seastead. With no kite, the wind on a Tension Circle House might push it faster than a Pipe Spar with a kite. So for a group of different seasteads to travel together sea anchors would be good to have. Also, some seasteads would need sea anchors to go slow enough for an annual migration.

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