Here for sale a Nomad buoy hull.  This unit came from a local university and we considered installing an engine and making it powered, however, do not have the time.  It is made from heavy aluminum. Ballast shown in the photo does not go with the buoy as we have used it on another vessel . A good hull for a boat project or a platform for instrumentation.  We will load on customers truck or put in the water at no charge to a successful buyer. Call Gary at 757-377-3535 during business hours for further info.
