The boat ramp named Southeast Dixie Highway 4901 in Port Salerno is a public boat ramp managed by Martin County. It is a concrete ramp that is 25 feet wide and has a gradual slope, making it suitable for a wide range of boats. The ramp provides direct access to the Manatee Pocket, which is a protected harbor on the eastern shore of Florida, located between Stuart and Port Salerno.

The Manatee Pocket is a tidal body of water that connects with the St. Lucie River, which flows into the Atlantic Ocean. The water is calm and shallow, making it ideal for small to medium-sized boats, such as flats boats, center consoles, and kayaks. Fishermen also frequent this area, as it is known for its excellent fishing opportunities, with many species of fish found in the waters, including snook, tarpon, trout, and redfish.

According to the latest information available, the Southeast Dixie Highway 4901 boat ramp is open 24 hours a day, seven days a week, and is free to use.
