Both the Kapten Boat Collars and the Waverider boats have 'inbuilt' hydrofoils, offering hydrodynamic performance for small boats - all based on the principle that you can't compress a liquid. Pat Jones - inventor, designer and owner of the Kapten Boat Collars & Waverider Boats - explains how his intensive research and development with Hydrofoils influenced his boat building mindset and how they've led to the designs of; first the Kapten Boat Collars and then the Waveriders boats, solving many problems associated with small boats.
