CAPTIVA, Fleet Supervisor Bureau of Commercial Fisheries Exploratory Fishing and Gear Research Base Pascagoula, Mississippi 39567 ABSTRACT This paper describes the United States Fish and Wildlife Service, Bureau of Commercial Fisheries research vessel Oregon II. The vessel has been designed for exploratory fishing and gear development studies in the tropical and subtropical portions of the western Atlantic, Gulf of Mexico, and Caribbean Sea. It will be 170 feet long, will have a mean draft of 12-1/2 feet, and a beam of 34 feet. Two 800- horsepower engines will propel it through a single propeller. The vessel incorporates many innovations for ease, safety, and flexibility in gear handling. INTRODUCTION Commercial fishery research and fishing gear studies of the United States Government are done by the Bureau of Commercial Fish eries of the United States Department of the Interior. This Bureau, which operates fishery research vessels in the Atlantic and Pacific Oceans, the Great Lakes, the Gulf of Mexico, and the Caribbean Sea, is now modernizing ., its fleet with new vessels. .' This paper describes the features of a modern fishery research vessel designed pri marily for exploratory fishing surveys, commercial- scale fishing operations, fishing gear development studies, and oceanographic research in the Gulf of Mexico, Caribbean Sea, and the tropical and subtropical Atlantic Ocean. This vessel, which is to be named Oregon g, is the seventh research vessel contracted for by the Bureau of Commercial Fisheries in the past 3 years. It replaces the fishery research vessel Oregon (figure 1) a converted 1 OO-foot tuna clipper that has carried out most of the fishery research work for the past 15 years in the Gulf and southwest Atlantic. Oregon !! will have much greater capabilities than her predecessor, for she has been designed expressly to: (1) meet the needs that have become apparent during the Figure l.--R. V.

GENERAL DESCRIPTION The hull forrrt is that of the North Atlantic distant water trawler, a vessel type con sidered to have superior seakeeping qualities. The conventional trawler deck arrangerrtent has been rrtodified to enable the vessel, with out further rigging or alteration, to function as a side trawler, stern trawler, double rigged shrirrtp trawler, purse seiner, longliner, gill netter, or shellfish dredger (fig. 4).
