1992 Systematic experiments in free-surface cavitation tunnel, followed by over a decade of theoretical and practical experience in understanding and utilising the flow past interceptors.

1994 Full-scale demonstration of the “hump-free” ability of interceptors. A full beam interceptor was devised for a 30 m monohull ferry (Chuan Chan) built by Austal Ships. The event that sparked this yard’s development of interceptors.

1995 A 7 mm full beam interceptor released the speed potential of Visotta, a 24 m motor yacht built
by Codecasa Due.

1997 Between 1994 and 1997 various interceptor arrangements were successfully devised for over
20 fast vessels around the world.

1998 US patent application filed in 1998 for the controllable interceptor unit today known as Humphree Interceptor. US patent granted in 1999 and European patent in 2003.

1999 Three Rodriquez Aquastrada monohulls retrofitted with Humphree Interceptors (in cooperation with Milan-based LA.ME Srl). On May 15 1999 Corsica Express III became the world’s first vessel to control its heading with interceptors. The event that sparked Rodriquez development of interceptors.

2001 The world’s largest high-speed ferry catamaran Stena Discovery retrofitted with Humphree interceptor steering system (in cooperation with LA.ME). Stena Voyager, Explorer and Carisma all later retrofitted with Humphree Interceptors.

Termination of cooperation with LA.ME.

2002 The first deliveries of a new sophisticated series
of Humphree Interceptor Systems featuring Humphree Interceptors in composite materials, electric servo actuators, self-configuring control network and a dedicated control panel that enables simple and intuitive operation.

2003 The world’s fastest yacht Fortuna retrofitted with a new steering system, featuring base-ventilated fins with electric actuated integral interceptors. Impressive improvements of course keeping, general handling and economy recorded.

2004 Performance boosting of superyacht 118 WallyPower by retrofitted base-ventilated stabilising fins and cavitation-free sea chest inlets.

2005 Volvo Penta worldwide release of a new boat trim system with interceptor units licensed through Humphree. Rating 5 out of 5, Motor Boat Monthly (09/04).

2006 Delivery of steering and ride control system, including Humphree Large Series interceptors (HLS) and dual interceptor T-foils.

2007 Delivery of interceptor systems for low wake and wash and automatic heeling control of the first high speed monohull ferries on Lake Geneva.

2008 Installation of the first fuel saving and low wash interceptor system for Vaxholmsbolaget’s fleet of ferries operating in the Stockholm Archipelago.
