The contribution of the field supervisors. Professors David J. 

 Ashton, Robert lA. Campbell, I«1yles S. Delano, Francis S. Doody, and 

 Albert Thompson is by no means less appreciated. A list of names 

 of the research staff and field workers appears in the supplement. 

 Our thanlis are extended to all of them and to Mr. Lloyd C. Peterson 

 and the staff of the IM Laboratory at Boston University. T\70 per- 

 sons, however, deserve special mention: I'Ir. Gerard C, St. Laurent, 

 for supeirvising the sampling aind for editing of the inteinriew 

 schedules and Mr. Clarence L. Sackett for his typing. Finally, it 

 is admitted that without the cooperation of the interviewed vessel 

 owners, insurance agents, and insurance companies, the project 

 could not have been conducted at all. 



Although help came from many directions, the reliability of 

 the data, the errors or omissions, in this report, as well as the 

 opinions expressed and the conclusions reached, are our ovm full 

 responsibility.
