Performance & Ecological Benifits

Performance & Ecological Benefits

For over 50 years, a wide variety of propeller guard designs have been developed with the idea of protecting water sport enthusiasts from injury and deaths caused by propeller strikes. During this period there has been a wide variety of designs that were exposed to the market. To date 100% of every safety design that has been offered to the public, also resulted in a significant decrease in vessel performance.

Although the MPT prime objectives are to deliver ecological and safety benefits, when Mr. Schultz and Mr. Smith developed the Thrustor® and Schultz Nozzle™ technology, their design objective was to create a system that would also address vessel performance. Their premise was that a safety or ecological goal that created a decrease in vessel performance would dramatically limit purchase response from the targeted sales categories. As a result of this dual approach to the patent design, MPT has created the following benefits for the Thrustor® and the Schultz Nozzle™ technology that include performance, safety & ecological benefits.

Performance Benefits:

It is anticipated that the patented technology will provide the following performance benefits.

Patented Multiple-Nozzle Venturi System reduces cavitation, increasing stability, control and responsiveness of the vessel.
Hydro-Lift action (stern lift) increases directional thrust and maneuverability.
Hydro-Lift action dramatically improves boating stability in all three hull axes (directions). This enhanced stability reduces the possibility of injury to passengers.
Hydro-Lift action dramatically increases bow visibility upon initial acceleration
Hydro-Lift action eliminates vessel Porpoising
Hydro-Lift action also dramatically reduces wake
Hydro-Lift action reduces the wake.
Multiple Nozzles shroud propeller reduces possibility of propeller strike damage.
Multiple Nozzle System expands rudder control to reduce possibility of broaching in a following sea
Extended skeg mount creates extra keel strength supporting transom weight of most boats
Adds safer, high speed maneuverability to all planing hulls.

Ecological & Safety Benefits:

It is anticipated that the patented technology will provide the following ecological and safety benefits.

Reduction of Fuel consumption at cruising speeds due to lower required RPM.

o On small craft at a 3500 Cruising RPM, preliminary Thrustor® testing resulted in speed increase of 5% or a reduction of up to 300 RPM to maintain the same speed, which will result in additional fuel savings of 5%.

o Since the 1930’s the Kort Nozzle at low speeds up to 9 knots, has a proven track record of delivering a 30% increase in Bollard pulling power, or a 30% fuel savings for displacement hull vessels under 10 knots

o Since the Schultz Nozzle™ speed threshold will exceed the hull speed of all commercial vessels; it is the only nozzle system that will work on vessels above 10 knots. We anticipate a minimum 10% to 20% fuel savings for all higher speed commercial vessels.

Reduces Hydro Carbon emissions by decreasing fuel consumption.

A reduction in cavitation reduces potentially dangerous frequencies to sea life.

Cavitation and vibration on sea life are currently under serious study.

Narrows the normally disruptive 360 degree propeller wash into a tight directional thrust towards the rear which:

Protects fish/egg habitat

Protects shallow-water plant habitat

Reduces beach erosion caused by normal prop wash

Reduce chances of a propeller strike to persons engaged in diving or water sports activates.

Reduces possibility of injury to marine mammals (Manatees, Whales, act…) from propeller strikes.
