thruster and a Northern Lights 12kW generator. Unlike the 42-foot WESMAC vessels CR had previously chartered, the Jamie Hanna does not have the typical split- pilothouse lobster boat design. Instead this vessel has a large full-width pilothouse with the lobster station, davit, block, and pot hauler aft of the pilothouse on the starboard side. The pi- lothouse has a large semi-enclosed helm area, with an array of electronics, including a Furuno NavNet 3D suite consisting of a black box, radar, echo sounder, and multiple ß atscreen monitors; an AIS, multiple VHF/loud hailers, and Sirius Satel- lite/Weather Radio. To assist with navigation, is a PC plotter with NOAA charts and HYPACK survey software. Behind the helm on the star- board side, is a 4-person dinette, and on the port side a sci-ence station with a large 10-foot built-in bench with rack stor- age. Down below, there are 4 berths with DC power and LED lights, a galley with full sized stove, refrigerator, and micro- wave, and a full head with heated shower. On deck, the Jamie Hanna has (2) 5000-lb capacity Pullmas-ter winches and can accommodate (2) oceanographic winch-es. The vessel has a rugged over-the-side transducer boom with fairing, a 5000-lb capacity 15-foot hydraulic A-frame, and nearly 500 square feet of open deck space. The hydraulic controls are located inside the pilothouse, rather than on deck. The Jamie Hanna underwent a pre-launch topographic survey per NOAA/NOS speciÞ cations to aid in the proper installation and calibration of multibeam systems and ancillary sensors. The transducer boom has a universal coupling with adaptors for RESON and Teledyne Odom multibeam systems to sup- port CRÕs survey contracts. A busy fall schedule is planned for the Jamie Hanna with demonstrations of OdomÕs new MB-1 multibeam system in Boston Harbor, a series of offshore RESON multibeam bathy- metric and Sediment ProÞ le Imaging camera surveys with Germano and Associates for the Army Corps of EngineersÕ Disposal Area Monitoring System (DAMOS) at sites in Mas- sachusetts and Maine, and an essential Þ sh habitat survey us- ing side scan sonar, underwater video, and benthic sampling along a submarine cable route in northern Maine for the U.S. Navy. CR and our clients are looking forward to the expand- ed capabilities of the 55-foot Jamie Hanna. This larger vessel will provide better sea keeping abilities for offshore work, and the improved accommodations will allow for 24 hour opera- tions and longer duration projects. On that launching day in August, more than twenty of JoshÕs friends and family took the half hour shakedown cruise from the Outward Bound dock to Thomaston, Maine. The vessel surpassed 21 knots and still allowed for quiet conversations in the spacious pilothouse. We quickly realized that this boat was well worth the wait. Dr. John ?Chip?
