Five technology families
Buoyancy engine
Changes the vessel’s buoyancy to dive, surface and hold a set depth.
Mapping underwater currents
Maps underwater currents from how the vehicles drift.
Multi-hull self-righting
Rights and recovers a vessel at sea, and reduces heeling moment.
Passive, automatic wingsail control
Sets the wing to the wind with no lines or pulleys, including a wingsail that doubles as a solar array.
Submerged sailing vessel
A sailing hull that rides below the waterline and submerges on command.
Counts cover the 11 issued U.S. patents listed below. Mapping underwater currents has 1 patent pending.
