After researching, I could not find any specific information about a boat ramp named West US 74 Highway 1333 in Rockingham, North Carolina with the given latitude and longitude coordinates. There are multiple boat ramps located in the area, but none match the given information.

However, in general, boat ramps can vary in size and type. Some may be concrete, while others may be gravel or dirt. The width of a boat ramp can also vary, but typically ranges from 10-20 feet.

The body of water that a boat ramp services can also vary. In the case of Rockingham, there are several bodies of water in the area, including the Pee Dee River, Blewett Falls Lake, and Hitchcock Creek.

The type of craft that are permitted on the water can also vary depending on the specific body of water and its regulations. Some bodies of water may only allow boats with electric motors, while others may allow larger boats with gasoline engines. It's important to check the regulations for each specific body of water before launching a boat.
