Executive Summary

Introduction

After several years of R&D testing and development, William C. Schultz and Terrence L. Smith filed a patent application in July of 2005 for a new marine technology, the “Multi-Nozzle Venturi System”, which significantly reduces cavitation and improves the overall performance of virtually all propeller-driven vessels. In addition for all displacement hull vessels there is a significant reduction in fuel consumption.

Each Multiple Nozzle assembly consists of two or more hydro dynamically shaped nozzles (hydro-foiled rings) that surround the propeller. This system creates “Venturi” ports, openings between the nozzles, which draft additional water into the area of cavitation, thereby increasing thrust and reducing cavitation. The increase in rudder and hydro-lift action results in substantially improved hull performance and maneuverability, reduction of propeller and shaft vibration, producing stability on any vessel equipped with the system.

The Thrustor® creates dramatic effects on planing hulls for stability, absolute helm and rudder control. This is the most significant technological advancement for outboard and sterndrive vessels since their inception over 80 years ago.

The Schultz Nozzle System for ships extends the high-performance values of the Kort Nozzle from slow-moving tugs to high speed blue water ships. This equates to the greatest economical and performance benefits in 76 years.

In July 2006, Mr. Smith founded Marine Propulsion Technologies, Inc. (MPT) a Subchapter S Corporation. MPT has been assigned ownership of the pending patent and all trademarks with the responsibility to make improvements and defend them as required. In 2007-08 MPT completed filing for US and world wide patent applications for the countries covered under the international Patent Cooperation Treaty (PCT). In addition, MPT is responsible for designing, testing, manufacturing, shipping, marketing and selling to the marine industry all products covered by the patent.

Key Considerations

The new MPT high speed Nozzle technology includes the design for a Skeg Keel mounting system, which allows the new Nozzle structure to fit all outboard and stern drive vessels. This mounting system is engineered to strengthen the skeg and support the transom weight of most planning hull vessels.

Target Markets

The Multi-Nozzle Venturi System has two different target categories of vessel use. The first target group is for outboard motor and stern drive boats mounted to the anti-cavitation plate and to the skeg of the lower end. The second application, for hull mount and azimuth (Z drive) vessels, will be suitable for large commercial shipping vessels, as well as all other inboard vessels.

MPT Targeted Marine Vessel Categories:

SKEG MOUNTED Outboard & Stern Drive Vessels

1. Recreational outboard/stern drive boats

2. Boating manufacturers

3. Outboard motor manufacturers

4. Houseboats

5. Pontoon boats

6. Sail boats

7. Skeg Munted

Inboard & Azimuth Drive Vessels

8. Commercial fishing vessels

9. Government/Navy vessels

10. Tug boats, barges & work boats

11. Merchant marine vessels

12. Passenger cruise ships

13. Recreational inboard boats

14. Inboard Racing boats

MPT will market to the above categories utilizing two different brand names:

First, we are providing all vessels which utilize either a stern drive of outboard motor and have propellers ranging in size from 5.5 inches to 18.5inches in diameter. We are marketing the system under the Thrustor® brand name. This category will include the entire consumer manufacturer pleasure craft market, military, commercial and working boat fleets which utilize motors ranging in size form 3 horsepower to over 350 horsepower. To fit all water craft in this category, the Thrustor® will be available in eleven sizes ranging form 6.5" to 19.5" diameters. The Thrustor® features a unique patented mounting system that is designed to fit all outboard motors and stern drive boats. They can even be mounted on a broken or damaged skeg.

Second, for all commercial vessels that requires a hull mount or azimuth drive, the system will be marketed under the name “Schultz Nozzle ™”. This includes vessels larger than 30 foot with an inboard motor. Propellers in this category range in size from 19 inches up to 15 feet in diameter.

The Schultz Nozzle ™ is designed to improve the operational performance and significantly reduce fuel consumption for every kind of commercial vessel including barges, bulk, cargo, container, chemical, fishing, liquefied gas, passenger, refrigerated, roll on/roll off, tanker, tug and vehicle vessels.
