About RAD

The founders of RAD Propulsion have a background in developing ground-breaking marine robotic ASVs for the Oil & Gas, defence and oceanographic sectors. It was here that they discovered that existing, on-the-market electric propulsion systems were lacking in smart, connected technologies, quality and durability.

RAD was formed in 2018 to develop high quality bespoke propulsion systems for all types of marine applications, from kayaks to zero emission vessels, using the expertise of a team of naval architects, systems engineers and automotive experts.
