ALUMINUM CATAMARAN PLANNED FOR OCEAN STUDY 



The largest aluminium -hulled cata- 

 maran (a 106-foot long, twin-hulled vessel) 

 in the United States is being constru-cted 

 at a Baltimore shipyard. The construction 

 was made possible by a National Science 

 Foundation design-and-construction grant 

 of more than $1.5 .million. The experi- 

 mental craft will contain the most modern 

 navigational and oceanographic equipment. 

 The vessel's streamlined, twin-hull design 

 is expected to provide lateral stability and 

 speed never b efo r e possible on oceano- 

 graphic surveys. The 11 -foot wide well 

 between the two hulls will provide a shel- 

 tered area for ocean-probing instruments 

 suspended from the main deck. 



The catamaran will be used for ocean- 

 ographic research by the Johns Hopkins 

 University, Dr, Donald Pritchard, profes- 

 sor of oceanography and director of t he 

 Johns Hopkins Chesapeake Bay Institute 

 said, "Hydrographic research can be ex- 

 tended further on the Atlantic continental 

 shelf and operations within the Chesapeake Bay will be less dependent on the weather."
