I can't really answer the question as I'm not black nor am I American, but maybe you could create the type of character you have in mind for a different ship if you're worried? I think it's a good thing to be sensitive with considering the origins of the name of the ship. Hope you get a helpful answer :) 

I'm so sorry about your dog :( and about how hot your room gets! I would have metled into a puddle in that heat, you're stronger than I am haha.
