R/V Gulf Surveyor was designed specifically for coastal hydrography and was constructed by All American Marine, Inc. (AAM) in Bellingham, WA and delivered in 2016. The overall design is based on the success of the R/V Auk that AAM built for NOAA in 2006, and the 45-foot R/V David Folger built for Middlebury College in 2012. At an overall length of 48 feet and beam of 18 feet, the catamaran vessel follows the advanced Teknicraft Design, Ltd. (Auckland, New Zealand). This includes a signature hull shape with symmetrical bow, asymmetrical tunnel, and integrated wave piercer. Main propulsion is provided by twin Cummins QSB 6.7 Tier 3 engines rated 250 bhp at 2600 rpm. Auxiliary power is supplied via a Cummins Onan 21.5kW generator. The suite of deck gear includes a hydraulic A-frame, hydraulic winch, electric scientific winch, knuckle boom crane, side mount sonar strut, davit, and moon pool with deployable sonar strut.
Scientists, professors, students, and industry partners utilized the vessel for work ranging from ASV support to data collection, teaching, mooring and buoy deployment and recovery, SCUBA diving and more. She is Coast Guard certified to carry up to 18 passengers on a Coastwise Route in the Gulf of Maine (not more than 20 nautical miles offshore).
