R/V ARABELLA is a 48 ft. (14.6 meter) fiberglass research vessel built in 1996 by Duffy and Duffy Custom Yacht, Brookline, Maine. Designed for near shore operations i.e. coastal to 50 miles offshore, the vessel is capable of supporting a wide range of scientific needs such as trawling, grab sampling, diving, seismic profiling, coring, AUV operations, etc.
R/V ARABELLA is powered by a single Detroit 12V71TA diesel engine. The vessel is capable of slow trolling speeds of 1 to 2 knots or cruising at 14+ knots. R/V ARABELLA also has an extensive hydraulic system to supply power to a large A-Frame, a single drum deck winch, a vertical capstan, bow thruster, and anchor windlass. A-frame lifting capacity is approximately 2500 lbs. and can handle structures up to 10 feet height and with a foot print of approximately 8 feet. In addition, a mast and boom capable of over-the-side operations, (lifting capability of approximately 1000lbs) is available. AC electric is supplied by a single 12.5 Kw 3-phase, 208/110 v, 50 amp Northern Lights M4843 generator. Heating and air conditioning are provided by a Marine Air reverse cycle system..
