20 Meter Hydrographic Survey Vessel

Swiftships’ 65 foot Hydrographic Survey Vessel (Conventional Propulsion) is a twin-screw diesel powered single chine vessel that provides a fast stable platform for hydrographic survey operations. Construction of the hull and superstructure is welded aluminum alloy, built in accordance to approved codes and regulatory standards.

The vessel features on the lower level a walk-in engine room, full galley and mess, and a berthing area. On the main deck a large survey data collection is located aft of the raised pilothouse. The provided working deck area connects directly to the survey data collection space. Ride, comfort, and maneuverability, are all characteristics of this deep ‘V’ hull design. In addition, the lifting strakes and stern wedge help the vessel maintain an even trim throughout a wide speed range. Outfitting is to the highest commercial standard with heavy emphasis on noise suppression.
