  In this article I discuss Zermelo's navigation problem in spacetime as a
geometrization of the frame dragging effect, and recast various examples
involving the latter into Zermelo form. I start by describing a stationary
spacetime in Zermelo's form and show that the Zermelo wind is the drift
velocity under frame dragging effect. Then we discuss various problems in this
context, such as Hubble expansion of the universe and accelerated frames in
special relativity. Another example I will discuss is the self-gravitating disk
around a black hole in post-Newtonian (PN1) approximation to describe the
anti-dragging effect in terms of a Zermelo wind.
