This bill applies only to the towns of North Topsail Beach, Surf City, and Topsail Beach. Enacts new GS 160A-205.6 to allow the towns to adopt ordinances prohibiting the abandonment of vessels in navigable waters within their jurisdictions. Applies the terms of GS 160A-303 to abandoned vessels in the same way that they apply to abandoned or junked motor vehicles. Defines an abandoned vessel as one that is (1) moored, anchored, or located for more than 30 days in a 180-day period without permission of the dock owner, or (2) in danger of sinking, has sunk, or is located in a way to be a hazard to navigation or danger to other vessels. Makes an exception to this definition for underwater archaeological remains such as shipwrecks that have been in place more than 10 years, unless removal is approved by the Department of Natural and Cultural Resources.
