"Preserve Maine Waters" Stickers
Maine Department of Environmental Protection.
In 2008, the purchase of a new sticker for owners of Maine-registered watercraft was automatically combined with the watercraft registration fee. The sticker, which now reads "Stop Aquatic Hitchhikers -- Preserve Maine Waters" and is physically attached to the Maine watercraft registration, has been required since 2002 for all motorized watercraft on inland waters. Owners of non-Maine registered boats will continue to be required to purchase and affix a separate nonresident sticker.
