Title: Innovator Lewis D. Madden: Pioneering Ice-Breaking Vessel Technology

Introduction

Lewis D. Madden, a distinguished inventor based in Morgan Hill, California, holds four patents that showcase his commitment to advancing maritime technology. His innovative approaches to vessel design reflect a deep understanding of both engineering principles and practical applications in challenging environments.

Latest Patents

Among his notable contributions are two key patents that highlight his ingenuity. The first, titled "Multi-hull vessel adapted for ice-breaking," introduces a multi-hulled vessel designed for upward ice-breaking. This vessel features side hulls that remain partially submerged while operating, equipped with ridges on their upper surfaces. As the vessel navigates through icy waters, the side hulls are strategically positioned under the ice, allowing for an upward trim angle that helps lift and break the ice efficiently.

The second patent, "Apparatus for reconfiguration of a variable-draft vessel," reveals a sophisticated vertical translation mechanism that reconfigures the hull form of a vessel with independently movable side and center hulls. This innovation utilizes a hydraulic-force actuator and a nonmetallic bearing, enabling precise control over the vertical movement and rotational orientation of the center hull in relation to the side hulls.
