The winter meeting of the Great Lakes and Great Rivers Section of The Society of Naval Architects and Marine Engineers was held at the Holiday Inn-French Quarter in Perrysburg, Ohio.

The first paper, presented by Mike Bisaillon of Aderco, Inc., Boisbriand, Quebec, was titled "Fuel Oil Additives: A Solution to Quality Problems of Modern Fuels." The thrust of his discussion was to present a possible solution to the problems encountered when matching availability of fuels to compatibility of modern equipment needs imposed by changes in the world market and refining. Evidence of the interest in this problem was apparent by the many questions following presentation of the paper.

Prof. Armin Trosch of the University of Michigan presented a paper titled "Effects of Non-Linearities on Hull Springing." He discussed the unique design challenge presented to the marine community by the long, flexible hulls and low draft/beam ratios of 1,000-foot bulk carriers on the Great Lakes, and the springing encountered in moderate seas. The occurrence of this springing caused the design agencies and regulatory bodies to re-evaluate the existing strength standards for Great Lakes vessels. An active question and answer session followed this presentation also. Following a coffee break, students from the department of Naval Architecture at the University of Michigan presented their senior design project. Presenting some unusual designs dealing with contemporary problems were: Paul Kopp and Tom Allen, "Modern Commuter Ship"; John Hardiman, "Multi-Use Commercial SWATH"; and Paul Rautenberg, "Advanced Submarine Concept Design." Following lunch the attendees toured the MarAd Great Lakes Fire-Fighting Training Center.
