Vessel hull for forming waveforms for attraction of aquatic animals

Abstract

A vessel for operation on a water surface, having a hull that creates a waveform that attracts aquatic animals such as dolphins when traveling at a speed of 9 to 13 knots. The hull comprises a bow, a rounded stern and a midship section extending from the bow to the stern. The hull has a ratio of a waterline beam to a radius of the stern in a range between 2.0-2.5, and a speed-to-length ratio in a range between 1.5-1.7 to create a soft, curling wake in which dolphins can surf and jump. The hull further has a length-to-beam ratio between 2.5 to 3.0, a flat bottom aft, a high deadrise at the bow, and a full midsection with a longitudinal center of gravity located 52% to 56% aft of a beginning of a waterline to result in a low prismatic coefficient of the hull.

Description

CROSS-REFERENCE TO RELATED APPLICATION AND CLAIM TO PRIORITY[0001]This application is a non-provisional application that claims priority to Provisional Application Ser. No. 63 / 050,600 filed Jul. 10, 2020, the disclosure of which is incorporated herein by reference in its entirety and to which priority is claimed.FIELD OF THE INVENTION[0002]The invention relates generally to attracting aquatic animals, and more particularly, to a power boat with a hull designed to create waveforms that attract aquatic animals, and a method for operating such a power boat for attracting aquatic animals using long period waves.BACKGROUND OF THE INVENTION[0003]Globally, the exploitation of marine mammals, such as dolphins, has shifted from hunting to viewing over the last few decades. Across the diverse spheres of wildlife tourism, whale and dolphin watching has grown more rapidly and globally in popularity than most, and since the first decade of the 21st century, most coastal cetacean populations have...

AI Technical Summary

Benefits of technology

The invention is about a new type of vessel for operating on water surfaces that creates a big wave when it moves at a certain speed. The vessel has a specific shape that helps attract aquatic animals. The technical effect of this invention is that it provides a more effective and efficient way to attract and engage with aquatic animals, which can be useful in various applications such as fishing, research, and tourism.

Problems solved by technology

Such complex signals are not readily reproduced by simple buzzers or other devices that generate signals of fixed frequency, duration, and amplitude or that are varied in an arbitrary manner.

However, currently existing sound emitting devices used by dolphin watching tour operators are complex, difficult to operate, unreliable and may further fail to emit certain types of sound for the attraction of aquatic animals.

The current systems may also lack certain features that limit their usefulness to boat tour operators.
