R/V Gulf Surveyor

R/V Gulf Surveyor is a state-of-the-art platform for hydrographic research, and the newest addition to the Center’s fleet. She is a 48-foot, twin screw, geared diesel, propeller driven catamaran built by All American Marine (Bellingham, WA) in 2015, and commissioned in January 2016. Her aluminum hull utilizes an advanced design developed by Teknicraft, Ltd. (Auckland, New Zealand) which provides a balanced combination of stability and comfort in a variety of sea states.

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).
