Benefits of technology

[0015] Yet a further aspect of the invention is characterized in that a maneuvering and dynamic stabilization system is provided which is capable of providing steering, braking, stabilization of roll / yaw oscillations, and obstacle / debris clearance functions, and which may be controlled by a human operator and / or microprocessor based control system. The maneuvering system exploits the ergonomic benefits and simplicity of a single control handle and single throttle control, facilitating human coordination between and sequencing of propulsion, maneuvering, retraction and throttle actions. The maneuvering system is hydrodynamically and statically balanced, and throttle position automatically maintained in set position, thereby enabling hands-free operation, if desired.

Problems solved by technology

However, Wang's mechanical assembly is complex and inconvenient in the manner in which it controls thrust magnitude and direction.
Further, the boat lacks efficient means for steering, dynamic stabilization and control and other practical requirements of watercraft handling.

Embodiment Construction

[0030] Referring to FIGS. 1 through 10, wherein like reference numerals refer to like components in the various views, there is illustrated therein a new and improved vessel propelled by oscillating fin with control mechanisms, generally denominated 100 herein.

[0031]FIG. 1 illustrates a preferred embodiment of the invention where boat hull 50 is propelled by a aftmounted marine propulsion system 200 driven by a person seated in operators seat 140 using pedal cranks 130 to drive the pivoting motion of the tail arm boom 220, and ultimately propulsion fin 210. The human operator, sitting in seat 140 steers with maneuvering mechanism 300, which is controlled by control handle 600, which is located ahead and to the right (starboard) of the operators seat. The pedal cranks 130 drive the reciprocal motion of drive cables 110 which are attached at the distal end to horizontal port and starboard crank arms 240 extending from the tail arm boom support pylon 230, causing the pivoting movement...

Abstract

A marine propulsion system emulates the fishes swimming motion yet is highly maneuverable as it permits changes from forward to reverse motion while underway. In other aspects, the propulsion system may be designed and optimized for efficient human powered propulsion.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claim priority to U.S. provisional patent application entitled “VESSEL PROPELLED BY OSCILLATING FIN WITH CONTROL MECHANISMS”, filed May 14, 2003 and having Ser. No. 60 / 470,954, which is incorporated herein by reference.BACKGROUND OF INVENTION [0002] The present invention relates to marine propulsion systems and methods, more specifically to a marine propulsion system that is highly efficient, in part, through emulation of a fishes swimming motion. [0003] U.S. Pat. No. 5,000,706 to Wang having issued on Mar. 19, 1991 teaches a rocker arm type propulsion mechanism for a personal water craft type boat which emulates some aspects of a fishes swimming motion. However, Wang's mechanical assembly is complex and inconvenient in the manner in which it controls thrust magnitude and direction. Further, the boat lacks efficient means for steering, dynamic stabilization and control and other practical requirements of watercraft hand...
