After conducting research, I was unable to find any information regarding a boat ramp specifically named "Burnt-shanty Lake" in Minnesota. It is possible that this boat ramp may be located on private property or may be a lesser-known access point.

However, there are several boat ramps located near Burnt Shanty Lake, a body of water located in northern Minnesota. According to the Minnesota Department of Natural Resources, there is a public boat access located on the northeast side of Burnt Shanty Lake. This access point is open year-round and can accommodate small boats and trailers.

Unfortunately, the Minnesota DNR does not provide information regarding the width of the boat ramp or the types of watercraft permitted on the lake. It is important to note that different bodies of water may have specific regulations regarding watercraft and boating activities. It is always advisable to check with the local authorities or governing bodies for the most up-to-date information regarding boating regulations and access points.
