Naruto might be in awe of the battleship Yamato at first. He could use his chakra to enhance the ship's speed or power in some way. For example, he could transfer some of his chakra to the engines to make it move faster.
In this fanfiction, it could also be that Naruto is on a mission related to the battleship Yamato. There could be an evil force that wants to use the power of the Yamato for its own malicious purposes. Naruto has to team up with the ship's crew, which includes some characters with unique abilities of their own. They all work together, with Naruto leading the charge against the enemy using his Nine - Tails chakra and his vast array of ninja skills.
Weiss, with her more refined upbringing, could initially be a bit shocked by the differences in the Yamato's world but would soon start to find ways to use her skills. She might help with strategic planning, using her knowledge from Beacon Academy.
One interesting storyline could be a crossover where the RWBY characters find themselves on the Battleship Yamato. Maybe they have to work together to face a common enemy that threatens both their worlds. For example, a Grimm invasion on the Yamato's world.
Well, if the Battleship Yamato time - travels, it might end up in a modern naval battle. With its huge guns, it could initially cause a lot of chaos. But modern ships have advanced radar and missiles. So it would probably be quickly outmatched.
I really liked a fanfic where they explored the backstories of the secondary characters on the Yamato. It gave a whole new depth to the story we know. By focusing on these often - overlooked characters, it showed a different side of the battleship's world and how everyone on board contributes to the overall mission.
The crew of the Battleship Yamato in a time - travel scenario would have mixed reactions. Some might be excited to explore this new world. Others would be fearful of the unknown. They would have to adapt to the new technologies or lack thereof in the new time they are in. For example, if they land in a primitive era, they would have to figure out how to survive without modern supplies. And if they land in a more advanced era, they would have to deal with the culture shock of seeing things far beyond their understanding.
