After conducting research, I was unable to find any information on a boat ramp named Canal Lock at the given latitude and longitude coordinates in Pennsylvania. It is possible that the information provided may be incorrect or outdated.

However, there are several boat ramps in Pennsylvania that service various bodies of water. The type of boat ramp and the size can vary depending on the location and the watercraft it is designed to accommodate. Some ramps may be concrete and paved, while others may be gravel or dirt.

In terms of the types of watercraft permitted on the water, this can also vary depending on the location and the regulations set forth by the governing authority. Some bodies of water may permit only motorized boats, while others may allow non-motorized watercraft such as kayaks and canoes.

It is important to always verify the latest information and regulations regarding boat ramps and watercraft access before planning a trip to ensure a safe and enjoyable experience.
