I apologize, but the coordinates provided are actually located in South Carolina, not Georgia. The boat ramp named William Hilton Parkway is located in Beaufort County, South Carolina, specifically on Hilton Head Island.
The William Hilton Parkway boat ramp is a public ramp that provides access to Broad Creek, which is a tidal creek that flows into Calibogue Sound. The ramp is approximately 25 feet wide, and can accommodate a variety of watercraft, including motorized boats, kayaks, canoes, and paddleboards.
According to the latest information available on the Beaufort County website, there are no size restrictions on boats using the ramp, but all vessels must comply with South Carolina boating laws and regulations. Additionally, the website states that there is a $10 launch fee for all watercraft using the ramp.
