ABSTRACT:
A marine speed nozzle assembly to be disposed in surrounding relation about a vessels propeller. The speed nozzle assembly includes an interior shell portion and an exterior shell portion, with the interior shell portion being structured in a circular configuration, so as to define an interior ring, and being disposed in concentrically surrounding relation about the propeller such that fluid propelled by the propeller flows from the interior shell portion's bow end towards its aft end and its generally hydrofoil-like interior longitudinal profile substantially increases a thrust produced by the propeller at low speeds. The exterior shell portion is similarly structured in a circular configuration, thereby defining an outer ring, and is secured to the interior shell portion substantially along corresponding bow and aft edges thereof. The exterior shell portion further includes a generally hydrofoil-like exterior longitudinal profile oriented such that a maximum spacing between the exterior shell portion and the interior shell portion is exhibited generally at the corresponding bow ends thereof, and such that a free running speed provided by the propeller that is surrounded by the interior shell portion is substantially maximized.
