RV SHEARWATER
The 110’ RV Shearwater combines a shallow draft, with excellent maneuverability and a wide range of capabilities for a vessel its size, making it a unique multi-purpose, cost effective platform, for marine surveying. The Shearwater was designed to fill a key need for our clients between small coastal, and large offshore, research vessels.
Despite its size and shallow draft, the Shearwater can operate on a 24hr basis, sleeps 22 people, and has a dedicated data acquisition lab.
Its Azimuth Drive propulsion system make it an ideal platform for both slow speed survey line navigation and station keeping for sampling activities.
Rounding out its capabilities, the Shearwater features two equipment moon-pools, a hull mounted multi-beam, a crane, hydraulic stern A-frame capable of splitting into 2 independent T-frames, fixed starboard A-frame, and dedicated equipment winches.
