We cannot tell how fast we are moving (for example, do not feel that Earth is moving very fast). This is related to how the objects move at constant speed in a straight line if no force is acting on them.
This is not the case in spherical or hyperbolic geometry, though (assuming a naive model of time*). In this visualization, every point in the yellowish "ghost" moves in a straight line at constant speed. The captain could tell how fast they are moving by measuring these distortions.
* not the case in (anti-)de Sitter spacetime, as in Relative Hell. https://zenorogue.itch.io/relative-hell
