After conducting thorough research, I was unable to find any information regarding a boat ramp named North Princess Street 398 in Shepherdstown, West Virginia. It is possible that this boat ramp does not exist or has been recently built and not yet documented.

Without any information available, it is impossible to determine the kind of boat ramp it is, how wide it is, what body of water it services, and what kind of craft are permitted on the water.

Therefore, it is important to always verify the accuracy of any information before relying on it. This can be done through various sources, such as government websites, local boating associations, and official tourism websites.
