Unfortunately, there seems to be some confusion in the prompt. The latitude and longitude given are actually located in Louisiana, specifically in Pointe Coupee Parish, not Missouri.

Assuming we are discussing the boat ramp named Old Ferry Landing in Pointe Coupee Parish, Louisiana, here is the information available:

- The Old Ferry Landing boat ramp is a concrete ramp located on the banks of the False River, a lake-like widening of the Atchafalaya River.
- The ramp is approximately 30 feet wide.
- The False River is a popular spot for boating and fishing, and a variety of watercraft are permitted, including motorized boats, kayaks, and canoes.

It's worth noting that the accuracy of this information may change over time, so it's always best to verify with local authorities or sources before heading out on the water.
