520 ILCS 5/2.19
It shall be unlawful to use a floating blind for the taking of migratory waterfowl, as permitted by this Act, unless such blind is anchored in a stationary position when in use. This does not prohibit the use of a scull boat in taking migratory waterfowl except where use of a scull boat is prohibited by Administrative Rule. A scull boat is defined as a boat propelled by means of an oar fixed in a notch in the transom of a boat and worked in a turning or sculling motion.
A floating blind is defined as any watercraft or floating structure that is camouflaged, disguised, or altered in appearance to offer a place of concealment and is capable of carrying a person. Such floating blind may be mechanically powered as long as such power is used only for movement to and from the place of hunting and no attempt is made to hunt during such movement.
