FYI on your boats..... this is from the ND G&F site.
"Motorboats are legal for going to and from shooting grounds. Ducks, coots, mergansers, geese and tundra swans may be taken from a floating craft, excluding a sinkbox, if such craft is beached, or fastened within or tied immediately alongside any type of fixed hunting blind, or from such craft resting at anchor. It is illegal to shoot from a sunken device or any floating vessel on open water or to use or cause to be used any floating battery, electric, steam, gasoline or other powered vessel in an attempt to take waterfowl. A motorboat, sailboat or other craft may be used to pick up dead or injured birds.
All watercraft must have aboard a U.S. Coast Guard approved life preserver for each occupant. Additionally, any watercraft powered by any motor (including electric motors) must be registered and numbered (licensed) through the North Dakota Game and Fish Department, or for nonresidents - through the state where principally used."
