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-

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.

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.

fairs in light of what he viewed
was a time of growth.
