PREFACE 



This report is published to provide coastal engineers recent field expe- 

 rience vd.th the design and construction of floating breakwaters on the west 

 coast of the United States. A similar report will be published on field expe- 

 rience with floating breakwaters on the east coast; both reports should pro- 

 vide practical guidance for coastal engineers. The work was carried out under 

 the U.S. Army Ckaastal Engineering Research Center's (CERC) Design of Floating 

 Breakwaters work unit, Coastal Structure Evaluation and Design Program, Coast- 

 al Engineering Area of Civil Works Research and Development. 



Tlie report was prepared by Professor Eugene P. Richey, Department of Civil 

 Engineering, University of Washington, Seattle, Washington, under contract 

 with the U.S. Army Engineer District, Seattle. J W. Heavner, Graduate Stu- 

 dent, Department of Civil Engineering, University of Washington, assisted with 

 field surveys and data collection. 



W.N. Seelig was the CERC monitor for this effort, under the general super- 

 vision of Dr. R.M. Sorensen, Chief, Coastal Processes and Structures Branch, 

 and Mr. R.P. Savage, Chief, Research Division.
