More Range – more top speed – more thrust

The new efficiency standard
in the boating industry

We developed the Hydro Impulse, a maritime impeller, to transfer more power into the water. In order to increase fun and action as well as reduce costs and CO2 emissions.

The Hydro Impulse

Our hydrodynamical optimized impeller design provides:

Up to 20% increased efficiency compared to propellers
Constantly high efficiency over the entire speed range
Hardly any cavitation
Fully integrable into hulls and foils
Fully covered rotating parts

The Hydro Impulse works with combustion engines and electric motors and all common propulsion systems from 10 kW to over 400 kW.

Hydro Impulse speed

Looking for the new propulsion standard in the boating and marine industry?

Offers a lot of benefits

We enhance the strengths and characteristics of different boats.
As with innovation efforts, inefficient propellers dilute the intended characteristics.

More fun and action

The higher efficiency brings more range, more top speed and more thrust. These are the basics for more fun and action.

Less consumption

With the same driving profile, the higher efficiency reduces fuel or energy consumption as well as costs.

ExcelLent Stop & Go

Our consistently high efficiency offers a greater advantage especially for heterogeneous driving profiles with a lot of stop & go.

Pleasantly quiet & smooth

The Hydro Impulse has virtually no cavitation. No cavitation means hardly any noise and vibration. This benefits passengers and wildlife.

safety & environment

Rotating or sharp-edged parts are covered. The risk of injuries for passengers or for divers and the environment are significantly reduced.

Do you see other benefits for yourself? Contact us and we will create the perfect match!

For a wide range of customers and use cases

The different characteristics result from the individual needs of the different user groups.
For all of them, boating serves its own purpose. And we make our contribution!

FAMILIES

Families are seeking fun and relaxation. Fun driving should not be neglected, as well as safety. If the pleasure is still quiet and without vibrations, it is almost perfect.

ELECTRIC BOATERS

Due to limited battery capacity, electric boats have a range problem. 20% more efficiency brings 20% more range, with higher top speed and higher acceleration.

TOWED WATER SPORTS

Water ski boats need efficient speed and a lot of thrust at the bottom. Propellers can only do that with high engine powers. We can do the same with much less power.

COACHING BOATS

The coaches need to get quickly to their trainees, then slowly escort them or pull them back to marina when the wind is calm. A heterogeneous driving profile to our taste.

TAXIBOATS AND FERRIES

Passenger boats have a special requirement with their regular stop & go and operating cost sensitivity. We enable lower acquisition, operating and maintenance costs.

TENDER AND SERVICE BOATS

Above all, yacht tenders must combine the power of a working boat, the speed of a sports boat and the sophistication of a luxury boat. Exactly our strengths.

DIFFERENT KIND OF OPERATORS

Acquisition, operating and maintenance costs are in the focus of all operators. Because we do the same with 20% less power, acquisition costs are reduced due to smaller engines. Operating costs are reduced due to lower fuel consumption, and our protection from ropes, wood and stones reduces maintenance costs.

BLUE-LIGHT ORGANIZATIONS

Blue-light organizations have their focus on “saving and protecting while not endangering lives.” Rescue missions need higher top speed, better drivability and constant operational readiness. Furthermore, covered rotating parts are mandatory for diving operations. When erecting oil booms, high and well-dosed thrust is required.

There are so many more use cases that we could provide a great benefit to!

In all major applications

Whether for outboard or inboard sterndrive, shaft motors, internal combustion engines, electric motors, hybrid engines, single and multihulls or even for foils.
The Hydro Impulse strengthens the advantages of the respective concepts!

HYDRO IMPULSE AS AN E-OUTBOARD MOTOR
ALL TYPES OF PROPULSION SYSTEMS

The Hydro Impulse can be integrated into any system via interfaces. In the case of the shown electric outboard, the underwater part was exchanged via an interface.

COMBUSTION ENGINES AND ELECTRIC MOTORS

Different performance and consumption characteristics influence the efficiency of the entire system. The Hydro Impulse can be optimized for different needs.

(MULTI) HULLS AND HYDROFOILS

Further efficiency can be gained by deeper integration into the hull through interaction between the Hydro Impulse and the hull (foils).

About us

We develop what makes boats and ships efficient. We developed the Hydro Impulse. The Hydro Impulse brings a lot of benefits to a wide range of customers and use cases for all major applications. With the Hydro Impulse, we increase fun and action while massively reducing CO2 emissions and costs.

WHY WE DO THIS

A component with 40% to 60% efficiency like the marine propeller would not stand a chance in other industries. Especially since turbofans in aviation operate at over 80%. Build on our experience and knowledge we are closing this gap. And of course, we are technicians and entrepreneurs, and love the sun and the sea!

WHY WE CAN DO THIS

We have experience with this technology since 1999, initiated first projects in aeronautics in 2007 and introduced a current market leader for model flight in 2011. In 2019, we intensified our work on the Hydro Impulse, tested the first prototype in 2020 and established the Hydro Impulse Systems GmbH in 2021.

WHAT WE FOCUS ON

We focus on the integration of the Hydro Impulse into various propulsion systems. For full potential we consider the interaction between and also integrate the Hydro Impulse into the hull. For special cases, such as world record runs, we develop performance parts and thus constantly expand our portfolio.

We are always looking for special cases, integration opportunities and partnerships.
