After conducting research, I was unable to find any definitive information regarding a boat ramp named Franklin at the given latitude and longitude coordinates in Virginia. It is possible that the ramp has been recently constructed and information has not yet been made public or documented online.

Without specific information regarding the Franklin boat ramp, it is impossible to determine its characteristics, including its size, servicing body of water, and allowed watercraft. If more information becomes available, I would be happy to assist in providing a more detailed analysis of this boat ramp.
