They actually have much better station keeping than this. The submerged part is not a sea anchor so much as horizontal sail that as it goes up and down pulls the float along, it uses this motion to drive in little circles around its station. They can only move about a knot and a half but have such a low profile as to be unaffected by the wind. I know this because I am sitting next to one in our lab.
