Overview
SEA-KIT's composite-hulled ocean survey USV family in 12 m and 15 m sizes.
The H-Class is a family of uncrewed ocean survey vessels from SEA-KIT International, the Essex company whose X-class boats are used by Fugro and others. Offered in 12- and 15-metre sizes, it uses a lighter composite hull and active stabilisers to travel faster and further than earlier designs while staying steady for sonar work. A retractable gondola holds a multibeam sonar, and winches lower profilers and tow side-scan sonars for deep-water and coastal mapping.
Primary Roles
Notes
Announced in June 2022 in 12 m and 15 m versions, both davit-launchable; the 12 m version fits a standard shipping container. A composite hull gives higher transit speed and range than SEA-KIT's X-class, and active stabilisers reduce roll. Payloads include a multibeam on a retractable gondola plus winch-deployed sensors. Designed to MCA Category 0 for over-the-horizon work, with Lloyd's Register UMS certification planned. Speed and endurance were not published.
