According to the Florida Fish and Wildlife Conservation Commission, the Peacock Bridge Road boat ramp in Marianna, Florida is a concrete double-lane ramp that provides access to the Chipola River. The ramp is reportedly 20 feet wide and can accommodate small to medium-sized boats.

The Chipola River is a freshwater river that flows for approximately 90 miles through Florida and Alabama. The river is known for its clear waters and abundant wildlife, including bass, bream, and catfish. The river is also popular for canoeing and kayaking.

As for what kind of craft are permitted on the water, the Florida Fish and Wildlife Conservation Commission states that all types of boats are allowed on the Chipola River, as long as they comply with state regulations for safety and environmental protection.

It's important to note that this information is accurate as of the time of writing, but it's always a good idea to double-check with local authorities or the Florida Fish and Wildlife Conservation Commission for the latest information and any changes or restrictions that may be in place.
