TECHNICAL PAPERS Fourteen technical papers were presented covering a broad range of interesting topics concerning vessel design for inland water- ways, coastal tankers, frigates, and surface effect ships. Other papers were concerned with top- ics such as inert gas and venti- lation systems, the marine envi- ronment, shell plating analysis, computer-aided design, hull and propeller roughness, integrated ducted propellers, hull and ma- WATER GROOVE WATER WEDGE SHOULDERS SOFT RUBBER How to get a cold shoulder and like it! Sometimes a "cold shoulder" can put you at a real disadvantage. With BFGoodrich Cutless® rubber bearings from Lucian Q. Moffitt, you'll get a cold shoulder that you'll like. Here's how. Thanks to a unique "Water Wedge" design, circulating water is carried over the shoulders of the bearing. The wedge of water, flowing through rounded rubber grooves, forms a lubricating film between the bearing and shaft. This allows heat to dissipate and keeps the bearing shoulders cool even when abrasive materials are present. By eliminating excessive friction and heat, two major causes of bearing failure, the bearing's service life is extended. Available world-wide through yards and marine stores. Or phone us for same-day shipment from our large inventory of Cutless rubber bearings that give you the cold shoulder you'll like. LUCIAN MOFf ITTJNC. NATIONAL and INTERNATIONAL DISTRIBUTORS P.O.

The highly acclaimed technical program was put together by the Papers Committee and was chaired by Jack Obermeyer. The papers were prepared by persons from Australia, China, England, Japan, Netherlands, and the U.S., representing industry, research institutes and organizations, na- val architectural firms, and the U.S. Navy. Two of the papers were the re- sult of cross-Atlantic and cross- Pacific cooperation. "Hydrody- namic Added-Mass Matrix of Vi- brating Ship Based on a Distri- bution of Hull Surface Sources" was authored by William S. Corus of the University of Michigan and Schelte Hylarides of the Netherlands Ship Model Basin. A paper entitled "Applications of a Computer-Aided, Optimal Prelim- inary Ship Structural Design Method" was written by Donald Liu and John Mahowald of the American Bureau of Shipping, and Owen Hughes of the Univer- sity of New South Wales, Aus- tralia. SNAME PRESIDENT Society president John J. Nachtsheim delivers his address to the members at the President's Luncheon. More than 500 persons attended the affair. In his address to the Soci- ety, SNAME president John J. Nachtsheim challenged the mem- bers to examine if they were "doing enough" in their involve- ment with the organization's af- fairs in light of what he viewed was a time of growth.
