A breakthrough marine technology being demonstrated at the current San Francisco Boat Show by the Bay Area’s own Velodyne Marine and inventor/entrepreneur David Hall promises freedom from sea sickness for boaters and is on display aboard the 'Martini 1.5' experimental vessel.


The latest version of Velodyne Marine’s series of experimental vessels, “Martini 1.5,“ is a 37-foot, powered catamaran, so dubbed for its ability to keep the contents of a martini in its glass – even at speeds of up to 50 miles per hour and in nearly five-foot swells.

The company explains that just as an automobile’s shocks stabilize its ride, Hall’s patented technology absorbs a vessel’s yaw, pitch and roll using two independent, stepped planing hulls attached to a deck by control arms. Four electro/pneumatic actuators – one acting on each corner – actively stabilize the deck. An onboard Velodyne-designed master control board receives inputs from onboard linear accelerometers, pressure transducers and a three-axis gyroscope and provides output to Velodyne-designed motor controllers and pneumatic solenoid valves – one pair of which controls each actuator.

Velodyne Marine add that “Martini 1.5” demonstrates a scalable, stable system that can be designed into any recreational, commercial or military vessel, thus paving the way to safer and more comfortable nautical travel in rough waters.
