After conducting some research, I was unable to find any specific information about a boat ramp named Hubbard County in Minnesota. It is possible that the name of the ramp is different or that it is a smaller, lesser-known location. Without more information, it is difficult to determine the kind of ramp or the body of water it services, let alone what kind of watercraft are permitted on the water.

It is important to note that Minnesota has many different bodies of water and boat ramps, each with their own unique rules and regulations. It is always a good idea to research specific locations before heading out to ensure that you have the necessary permits and are aware of any restrictions. Additionally, it is always important to follow proper boating safety procedures and guidelines to ensure a safe and enjoyable experience on the water.
