I'm sorry, but I could not find any specific information on a marina named "KB DERR & SON" in the United States. It's possible that this marina is either a small, privately owned location or perhaps not widely known or documented in major databases or publications.

If you have any additional information or context that could help narrow down the search, such as the state or city where it is located, I would be glad to help further. Alternatively, you might find more detailed and specific information by reaching out to local boating communities, visiting regional marina directories, or contacting local chambers of commerce.
