After conducting research, I was unable to find specific information about the boat ramp named VT 17 Addison in Vermont. It is possible that the name has changed or that the ramp is no longer in use. Without more information, it is difficult to determine what kind of boat ramp it is, how wide it is, and what body of water it services.

However, I can provide general information about boat ramps in Vermont. According to the Vermont Fish & Wildlife Department, Vermont has over 150 developed boat access areas that provide access to lakes, rivers, and ponds throughout the state. These access areas vary in size and amenities, but most are designed to accommodate motorized watercraft such as powerboats, jet skis, and pontoon boats. Some access areas may also be suitable for non-motorized watercraft like kayaks and canoes.

It is important to note that each access area may have specific rules and regulations regarding the use of watercraft. These rules may include restrictions on the type of watercraft that are allowed, as well as requirements for permits, safety equipment, and other measures to protect the environment and wildlife. Boaters should always check the latest information and regulations before using a boat ramp in Vermont or any other location.
