A ship is moving along the ocean, the propeller thrust of which is balanced with the resistance of the water, as a result of which the ship moves uniformly – with a constant speed. Can we say that this is a movement by inertia.

Newton’s first law says: There are such frames of reference, called inertial, relative to which bodies are at rest or move rectilinearly and uniformly in the absence of external forces or if
these forces are balanced.
This motion is inertial motion. According to the above: yes, the movement of the ship can be considered as inertial motion.
