No, I didn't.
I don't understand how he could know that the ship would "lurch" so violently that it threw everything (including people) around, cause interior damage even though he was a watch officer, and that he could maintain enough balance to realize that the ship was moving and it was not simply the pressure differences on his middle ear that would cause him to
think that he was moving.
Want a demonstration? Go to a big open space, hold out your arms (for the dramatic effect), and spin around really fast for twenty full revolutions. Now stop suddenly. Look! The ground is moving!
The huge blast from 9 sixteen-inch cannon firing at once (fast enough that you cannot tell the time between shots) causes UNBELIVEABLE air pressure forces in and around the ship, hatches closed or not. This major increase in pressure causes wonders on the ear structures, especially the middle ear (that controls balance). As such, he would have thought he was moving simply when he was only being thrown around by the immense air pressure wave from the salvo. When he got to his feet, he still would have thought he was moving, yet he is only being tricked by his own brain.
Jesus, I feel like such a medical-nerd. Maby I am...
