Authorized under Public Law 17–7, the marina operational functions were transferred from the Department of Parks and recreation to PAG in the early 1980's. This gave the Port Authority responsibility of managing and maintaining the Agana Boat Basin, now known as Gregorio D. Perez Marina, and other future recreational boating marinas. Today the Port owns and operates four recreational boating marinas with over 150 dock slip leased to various tenants.
