Title: Innovations by Alberto Alvarez Calderon

Introduction

Alberto Alvarez Calderon is a notable inventor based in La Jolla, California. He has made significant contributions to the field of marine design, particularly in the development of innovative hull shapes and sailing yacht concepts. With a total of 2 patents, his work reflects a deep understanding of hydrodynamics and performance optimization.

Latest Patents

Alvarez Calderon's latest patents include the "Transonic Hydrofield" and "Transonic Hull." The transonic hydrofield defines the shape of a displacement transonic hull (TH), characterized by the absence of curvatures such as shoulders, midbody, or rear quarter. This design features a deep draft forward and a shallow draft aft, effectively eliminating surface wave-making sources typical of conventional displacement hulls. The corresponding transonic hull has a substantially triangular waterplane in dynamic displacement conditions, with maximum draft forward and minimum draft aft. Additionally, the planing lateral surfaces are inclined at a large angle, vertical to the waterplane.

His second patent focuses on a high-performance sailing yacht design based on a keelless concept. This design incorporates dynamic gravitational ballast that is laterally movable for heeling resistance, replacing the standard keel's function. The keelless yacht features an adjustable flap mounted on an elongated strut, from which the ballast is suspended below the hull. This configuration generates a variable heel hydrodynamic control force independently of the counter-heeling effect achieved by the ballast. The design enhances the effects of improvements and modifications to hull design, featuring a duplex form with upper and lower hull shapes.
