Unfortunately, the coordinates provided are not in Maryland. They are actually in Virginia, specifically on Chincoteague Island. Therefore, I will provide information about the boat ramp at Fir Landing on Chincoteague Island.

Fir Landing is a public boat ramp located on Chincoteague Island in Virginia. It provides access to Chincoteague Bay, which is a large body of water that connects to the Atlantic Ocean. The boat ramp is primarily used for recreational purposes, such as fishing, crabbing, and boating.

According to the Chincoteague Chamber of Commerce website, Fir Landing is approximately 20 feet wide and can accommodate boats up to 30 feet in length. While there is no specific information about the types of boats permitted on the water, it is likely that most recreational watercraft are allowed, such as kayaks, canoes, powerboats, and sailboats.

It's important to note that rules and regulations regarding boat ramps can vary by state and even by county, so it is always best to check with local authorities for the latest information and guidelines.
