Comment on French aircraft carrier Charles de Gaulle tracked via Strava activity in OPSEC failure

You don’t need that assumption. Your assumption can just be “the person and vessel don’t diverge significantly over time”.
Then, if you treat velocity as a vector and compute the average velocity vector over time, you’ll have a pretty close estimation to the vessel’s velocity vector.
After all, if those two average vectors (vessel’s and person’s) were to differ much, they would end up in different locations.
