After conducting research, I was unable to find any information about a boat ramp named Thistle Creek in Oregon with the given latitude and longitude coordinates. It is possible that the name or coordinates are incorrect or that the boat ramp is not widely known or documented.

Therefore, I am unable to provide accurate information about the type of boat ramp, its width, or the body of water it services. Additionally, I cannot confirm what types of watercraft are permitted on the water as it is unclear which specific body of water the Thistle Creek boat ramp would be servicing.

If more information becomes available, I will be happy to provide an update.
