And of course the guns have shock absorbers that take out most of the recoil, because it would break the ship otherwise.
I don't place much faith in that guy's calculations. He has had to amend the result several times because of incompleteness etc. Also, this whole section, "This means that if the ship actually moved 30 feet, then it would have do this in the half a second that the guns are recoiling as all force pushing the ship ends when the guns reach their recoil limits", fails to take into account motion might continue longer because of momentum.
Anyway, that explanation "just the water being broiled up by the muzzle blasts" certainly is most of the visible effect.
When the Lamb broke the fourth seal, I heard the voice of the fourth living creature saying, "Come." I looked, and behold, an ashen horse; and he who sat on it had the name Death; and Hades was following with him. Authority was given to them over a fourth of the earth, to kill with sword and with famine and with pestilence and by the wild beasts of the earth.
— Revelation 6:7–8 NASB
12 And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood;
13 And the stars of the heavens fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind.
14 And the heavens departed as a scroll when it is rolled together; and every mountain and island were moved out of their places.
15 And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains;
16 And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb:
17 For the great day of his wrath is come; and who shall be able to stand?
1 And when he had opened the seventh seal, there was silence in heaven about the space of half an hour.
2 And I saw the seven angels which stood before God; and to them were given seven trumpets.
3 And another angel came and stood at the altar, having a golden censer; and there was given unto him much incense, that he should offer [it] with the prayers of all saints upon the golden altar which was before the throne.
4 And the smoke of the incense, [which came] with the prayers of the saints, ascended up before God out of the angel's hand.
5 And the angel took the censer, and filled it with fire of the altar, and cast [it] into the earth: and there were voices, and thunderings, and lightnings, and an earthquake.
6 And the seven angels which had the seven trumpets prepared themselves to sound.

Each time he's just adding more moving mass to the calculation, making it less favorable for his point.
>fails to take into account motion might continue longer because of momentum.
The acceleration has to take place while the force/impulse is acting. It's possible that the ship -eventually- moves 30 feet, but the impulse will only impart a maximum recoil speed around 0.5 feet per second assuming no friction or resistance, just pure transfer of momentum, so it would have to do so over a full minute. With the entire ship pushing broadside against millions of tons of water, it's not going anywhere.
