Two chapters ago Neinhart knocked Kagura and Jellal all the way through the ship and out the bottom, leaving a more than man-sized hole in it.

With such a big hole a real-world sailing ship would have already been at the bottom of the ocean at the start of the chapter.

But appartently those Alvarez people have some serious know-how for building unsinkable ships. ^^
