REGENT Craft, a US-based developer and manufacturer of all-electric seagliders, has submitted its design basis agreement (DBA) for the 12-passenger Viceroy seaglider to the U.S. Coast Guard (USCG), advancing its maritime certification process for seagliders—high-speed, all-electric vessels that operate exclusively over the water.

As explained, the DBA establishes what the Viceroy seaglider design must do to show an equivalent level of safety to other similarly sized certified vessels and consists of a concept synopsis, regulatory analysis, and risk/hazard analysis.
