Ken Hoffman(United States):
Other observers in different Inertial Reference Frames relative to the moving boat, depending on their position relative to the boat, whether stationary or a constant velocity vector, could each find a unique “preinertia” velocity vector or none to account for what is seen. So, the observer cannot be removed from the question as regards what role he may play. How he observes what he sees comes into play.
In the early days of film innovation, it was scientifically determined that a frame rate of less than 16 frames per second caused the mind to see flashing images. Audiences still interpret motion at rates as low as ten frames per second or slower (as in a flip-book) …If the book is flipped at a fast enough speed, the illusion of smooth motion is created.…” Although scientists do not yet agree as to the precise mind/body mechanism of this phenomenon, its existence is real. It has been called Persistence of Vision.
The eye is not a camera, and the data must be processed through the brain which takes time.
The mind settles for some perception to make sense of the event.
There is a delay and holding effect of the photon data (about 0.1 sec) to the brain to give the impression of an action or a path that makes sense to the observer receiving that information.
Physics still does not see that the observer is also another object subject to relativity and what he observes may also be an illusion to make sense of it.
This is shown in examples from easy flip books of fixed picture drawings to complicated electronic displays.
