The O’Hara family and Eastern Shipbuilding are no strangers to each other. The F/T ARAHO is the sixth fishing vessel Eastern has built for the O’Hara family over the last 20 years.

Between the years 2002-2005 four additional fishing vessels were delivered.

The O'Hara family has been in the maritime industry for over a century. Starting in Massachusetts, Francis J. O'Hara began building his sailing fleet in 1903; after four generations, the process continues. The O’Hara fishing family has grown over the past century. In 1978, Eastern Fisheries was created through a partnership between Frank O’Hara Sr. and Roy Enoksen. Today, Eastern Fisheries is one of the world’s largest scallop fleets and processes over 20% of the scallops consumed in the U.S. Moving from generation to generation with fishing fleet operations on both the Atlantic and Pacific Oceans, in addition, O’Hara Corporation operates three catcher-processor vessels in the Bering Sea, Aleutian Islands and Gulf of Alaska. The O’Hara family also own and operate O’Hara Lobster Bait that has been supplying bait to lobsterman on the coast of Maine for over 65 years and Journey’s End Marina also located in Rockland Harbor, Maine which is the largest indoor boat storage facility in the state offering an array of services and vessel repairs.
