Experiments were performed with a three-bladed model pro- peller in a water tunnel at the David Taylor Naval Ship Re- search and Development Center. Commercial protective coatings were evaluated, as well as the effects of ships' wakes. The report makes a number of conclusions concerning the ef- fect of characteristics of wakes upon erosive impact intensity of cavitation. The report recom- mends that additional research be conducted to further deter- mine the critical wake character- istics affecting cavitation erosion, and that further research into protective coatings should be per- formed. The report is available from the National Technical Informa- tion Service, 5285 Port Royal Road, Springfield, Va. 22161, for $5.50 per copy. Its order number is PB268899/AS. Argentine Shipyards Get Boost From Spain The Argentine shipbuilding in- dustry has received a $250 mil- lion line of credit from the Banco Exterior of Spain. The president of the Banco Exterior, Jose Garcia Hernandez, met with officials of the Argen- tina National Development Bank in Buenos Aires recently to sign the agreement. The funds will pay for new ship construction. Argentina has added two ships to its rapidly expanding merchant fleet — the Almirante Storni, a cargo vessel, and the Ciudad de Ensenada, a grain and mineral carrier. The country's state-owned ship company, ELMA, also announced it expects to add six more vessels to the fleet in the near future to handle an expected increase in shipping. Line Fast's new Fastloc® has many timesaving features, such as the anti-jamming device for free lever operation which eliminates one of the major problems encountered in leverlock securing. Another time and money saving feature is the "Dog Bone", which enables side-by-side bridging of stacked containers. The Fastloc® can be installed safely and speedily to the bottom of a container before it is lifted aboard the ship. This bottom lock feature, together with a pole- activated handle, eliminates the need to have men climbing atop the containers. We promised for years to be ahead of our competition and we kept our promise again. For more information, write or call...
