Graphic design for a large vinyl wrap

Doing some design work for a wrap for my buddies boat. It's a 31ft boat, so the final images will be fairly large.

Is there anything I need to keep in mind given the large size? I was planning to have vector files of the images, as the background will be solid black. Just not sure what the shop will need file/image wise for something like this.

Anyone have experience with something along these lines?
