Wisconsin is one of the strictest states when it comes to vessel documentation. Whether you’ve just purchased a boat or are selling a boat in Wisconsin, the Wisconsin DNR requires virtually all watercraft to be registered — including motorized boats, sailboats over 12 feet, and even some non-motorized vessels if used on public waters.
