After conducting research, I was unable to find any concrete information on the Powhatan Point Boat Launch in Ohio. It is possible that this boat ramp is a small, local facility that has not been documented online.

However, based on the available information regarding boat launches in Ohio, here is some general information that may be helpful:

- Boat ramps in Ohio are typically categorized based on the size of the watercraft they can accommodate. Categories include "small craft," "medium craft," and "large craft."
- The width of a boat ramp can vary depending on the size of the watercraft it services. However, most ramps are at least 20-30 feet wide to accommodate trailers.
- Ohio has numerous bodies of water that are popular for boating, including Lake Erie, the Ohio River, and various inland lakes and reservoirs.
- The types of watercraft permitted on a particular body of water can vary based on regulations and restrictions. For example, some lakes may only allow boats with electric motors, while others may permit gas-powered boats up to a certain size.

Again, without specific information on the Powhatan Point Boat Launch, it is impossible to provide accurate details about this particular facility.
