2 May 1967 LETTER OF PROMULGATION The widespread interest in the previous editions of "Boats of the United States Navy," by numerous agencies and individuals as well as branches of the Department of Defense, has prompted the publication of this revised edition. Catalogued herein are the principal characteristics of most of the boats and small craft presently in use by the Navy. ----ljvv.,~ EDWARD J. FA~ Rear Admiral, 1 DEPARTMENT OF THE NAVY, NAVAL SHIP SYSTEMS COMMAND, WASHINGTON, D.C Prepared by NAVSEC, Norfolk Division, SEC 6660, U.S. Nava l Station, Building API3, Norfolk, Vi rginia For sale by the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C Price $2.75

3 INTRODUCTION This book is arranged by length. A cross index by boat types follows this page. DEFINITIONS A Navy boat is defined as an uncommissioned waterborne unit of the Fleet, not designated as a service craft, and capable of limited independent operation. It may be assigned to and carried on a ship as a ship's boat or assigned to a shore station or a fleet operating unit. The term ''hoisting weight" as used herein is defined as the weight of the boat completely fitted out and ready for service with machinery and electrical installation in operating condition. All outfit, navigational, li.fesaving equipment and crew are on board. The fuel tanks are full, except in special bases as noted. The weight of personnel is estimated to be 165 pounds per man and 225 pounds per man for a combat equipped marine. The accompanying illustrations are to a scale of 1/8" = 1'-0". Inflatable boats are to a scale of 1/4" = 1'-0".
