After conducting research, I could not find any information on a boat ramp named "Beach City Dam Launch Ramp" located at the latitude and longitude provided in Ohio. It is possible that the name or location has changed, or that the ramp no longer exists.

To accurately answer the questions posed, more specific information is needed. Without further details, it is impossible to determine what kind of boat ramp it is, its width, what body of water it services, or what kind of watercraft are permitted to use it.
